Urentius echinus D. and Urentius sentis D. Brinjal Diseases or Egg Plant Diseases : Brinjal Filed. Aphids are found in large colonies on underside o leaves and tender shoots. It is estimated that the combined infestation of pest and diseases in crop plants could take a heavy toll up to 50% losses in attainable yield in many crops especially major food crops like rice, wheat and maize. Major pests 1. The correlation analysis showed highly significant positive correlationship between predator and aphid species. In Pakistan, the cul-tivated area under brinjal crop is 8575ha with annual production of 87,587 tonnes (FAO, 2018). Lucinodes orbonalis Guen Spraying of insecticides like Dichlorvos (0.02%) or Chlorpyriphos (0.05%) with fish oil rosin soap was found to control the insect population. Crop should be maintained weed free for 4 to 6 weeks after by resorting to timely hand hoeing and hand weeding; III. Aleurodicus dispersus (Hemiptera : Aleurodidae) is polyphagous pest of many agricultural, horticultural, floricultural and nonagricultural plants. How many to use: 6 Traps / acre or 12-15 traps / hectare. There is extreme need for pesticidal alterations in integrated pest management. A successful plant disease management mainly depends on accurate, efficient and quick detection of plant pathogens from a symptomatic plant. The damage caused by insect change from season to season since direct temperature and high moisture support the populace develop of brinjal shoot and fruit borer [43,44]. 2001) that helps to reduce the risk of heart disease, stroke, certain types of cancer, gastrointestinal issues, high blood pressure, eye disease and many more. Second dominant family was Ichneumonidae with 36 species followed by Eulophidae, Trichogrammatidae, Chalcidae and Aphelinidae by the numbers 7, 7, 6 and 1 respectively. The full grown larva comes out and pupation takes place in boat shaped cocoons on the plant itself. The nymphs are completed in 7 to 9 days and several generations are completed in a season. This paper . It is minor pest of brinjal in the State of Maharashtra. Note: For commercial high yielding Brinjal Varieties in your local region, contact horticulture department. They live like a colony on the bottom of the leaves, on the flowers or inflorescences and young sprouts. Removal and destruction of affected shoot and fruits alongwith larvae. The primary damage caused by aphids to eggplants is the production of sticky honeydew and subsequent growth of black sooty mold on the honeydew. Hymenpterous parasitoids are biopesticides scattered in the environment which develop on pest insects and kill them. Plants exhibiting aphid damage can have a variety of symptoms, such as decreased growth rates, mottled leaves, yellowing, stunted growth, curled leaves, browning, wilting, low yields, and death. It also create sooty moulds on leaves which affect photosynthesis, growth and yield of the crops. T.V. Spraying with 0.05% endosulfan, 0.03% Dimethoate or thiometon and 0.02% phosphamidon control the pest effectively. Low relative humidity favours mite multiplication. Family: – Noctuidae They grow on the spontaneous flora, and then migrate on cultivated species. Family: -Aphididae Published November 8, 2012 at × in Photographs. The book contain Lepidopterous, Orthopterous, Hemipterous, Coleopterous pests and fungi, bacterial and viral diseases of mulberry. Ecological control of insect pests is very sound and ecofriendly alternative for chemical control in pest management strategies. The holes later plugged with excreta leaving no visible sign of infestation. Brinjal (Solanum melongena L.), also called aubergine or egg plant, is one of the top ten vegetables grown in the world. Family: – Pyralidae The major insect pests were found in brinjal field viz. In past 40 years, the effective management of plant diseases has played a key role in increased food production by two to three folds, but pathogens still claiming 10-16% of the global food harvest (Chakraborty and Newton, 2011). jassids, white flies, fruit borers and mites. vigintioctopunctata (Fab. A single female lays about 35-45 eggs, which hatch within 4-12 days. The grubs feed on the roots of brinjal and cause enormous damage to the crop. Lower whitefly populations were observed on whitefly pre-infested brinjal plants compared to aphid pre-infested and control plants. Their abundance, damage, life cycle and control were reported on teak from the fields of western Maharashtra. Seasonal abundance of different species on brinjal from Kolhapur region. Damage symptoms Larva bores into tender shoots and causes withering of terminal shoots / dead hearts - also bores petioles of leaves, flower buds and developing buds, causes withering of leaves, shedding of … Control: Unlike the adults, the crawlers are free from waxy coating and therefore the crawler stage is the most effective for spraying pesticides. Damping Off: The disease causes acute damage in the nursery. Apanteles creatonoti Viereck (Hymenoptera : Braconidae) is potential bicontrol agent of insect pests such as Spilosoma obliqua (Walker), Amsacta moorei Butler, Amsacta albistriga Walker and Thiocidas postica Wlk. The total worldwide food and preharvest losses due to insect pests, plant pathogens and weeds were estimated to be about 45% (of total food production) and 30%, respectively (Pimentel and Levitan 1986). It is attacked by 30 species of insect pests belonging to genera Myllocerus, Astycus, Trachypholis, Xyloborus, Cryphalus, Silvanus, Eugonius, Plateros, Psiloptera, Adelocera, Mesomorpha, Aspidomorpha, Aegosoma, Gelonaetha etc. The collected insects were identified, in table-1. the paper. 4. Therefore, [12] mentioned that the population of whitefly (2.80/leaf) was increased in the first week of November. These Brinjal Varieties and yield may vary from region to region. 37 Full PDFs related to this paper. The most common sucking insect pests’ attacks on brinjal are aphid (Aphis gossypii), jassid (Amrasca biguttula) and whitefly (Bemisia tabaci) [6]. 32. The summer crop suffers comparatively more. The use of pesticides leads tremendous pressure on various ecosystems causing pest resistance, secondary pest outbreak, pest resurgence, pollution, health hazards and destruction to ecocycles. moisture & input regimes, brinjal is more prone to pest attack and at a conservative estimate cause about 35-40% losses. Spraying with 0.05% endosulfan, 0.02% phosphamidon, 0.03% dimethoate, methyl demeton or thiometon control the pest effectively. The mite is a pest of brinjal. of Zoology, Krishna Mahavidhyalaya, Ret. Jassids (A. biguttula biguttula Ishida), aphid (A. gossypii Glov.) The summer crop suffers comparatively more. The results revealed that the peak incidence of aphids, jassids and whitefly was in the 34 th, 35 and 36th standard meterological week (SMW), respectively. As a result, the leaves are completely skeletonized leaving only a network of veins. L. orbonalis, A. bigutulla bigutulla. Vegetable cultivation is an important and alternative source of income, especially in urban and suburban areas. shoot and fruit damage by Leucinodes orbonalis Guen. It is one of the most serious pests of brinjal fruits and plants. It also provides details of rearing technology of pests and parasitoids. and Monophlebus and Aleurodicus of order Hemiptera. Aphids are small, pear-shaped, gregarious insects. Nymphs are oval, greenish yellow with few black dots. Among the larval stages of C. septempunctata, the fourth instar larvae consumed more number of L erysimi and in the adult stages female consumed more then male beetle. Use organic … 1. In all there are 14 chapters. The order of preference for parasitism was A. moorei > A. albistriga > T. postica > S. obliqua > S. litura. The short pinkish larva will be induced into terminal shoots which results in withering and drying of the shoot. They measure about 3mm long. Plant diseases alone can cause almost 20% reductions in yield in major food and cash crops worldwide. In case of severe infestation, this black coating is so Bilasini and Singh (2012) noted the larvae as. Brinjal Disease. Urentius echinus D. and Urentius sentis D. We use cookies to ensure that we give you the best experience on our website. Agrochemicals play an important role in protecting the crops from pests and diseases and thus, increase the yield.

Several workers recorded various groups of natural enemies on L. orbonalis viz., The ichneumonids Peristomerus testaceus, Eriborus argentiopilosus (Tewari, and Singh 1987), Bracon chinensis Nair, R.K., 1967, Apanteles spp., Chelonus spp, (Gokulpur, R.S., 1970;Navasero, and Calilung,1990 and the chalcids Brachymeria obscurata (Walker). In case of heavy root damage, the whole plant is affected, while partial damage leads to poor growth of plants. Myzus persicae Sulz Affected leaves become mottled, turn brown and fall. When the fruits are infested, they can be entirely covered with the mealy bug. /ha effectively reduces the nematode population in the field. Custard apple Annona reticulate, Mango Mangifera indica L., Sunflower Heliantus annuus L., Cowpea Vigna unguiculata L., Tomato Solanum lycopersicum L., China Rose Hibiscus rosasinensis L. and several grasses have also been attacked by A. disparsus in Kolhapur region, India. Trap re-usability: Can be used up to 5 seasons if trap is stored in good condition after each season's harvest. All rights reserved. Application of Aldicarb or Carbofuran @1-2 kg a.i. T. chilonis 1 to 1.5 lakh/ha was found effective for the management of BSFB as ecofriendly control. The infestation on brinjal can be as high as 70 per cent. 81. Aphids are small, soft-bodied insects that vary in color from pale yellow to red to green to black, depending on the species (with one species capable of having several colors), the host plant, and time of season. Specially biotic and abiotic factors and their role in pest control. The sucking insect pests were more common on crop plant of yellow flowers. transmission of little leaf disease in brinjal. Spraying the crop with Malathion (2ml/litre of water) or Carbaryl (2-4 g/litre of water) effectively controls the pest. Oviposition, incubation, larval and pupal periods of E. perticella ranged from 4-11, 3-9, 29-47 and 7-14 days, respectively, whereas adult longevity were 4-8 days for male and 5-13 days for females. If the flower blooms are attacked, the fruit set is affected. They pierce plant tissue with needlelike mouthparts, which may result in blossom shed or curling or stunting of new growth. This pest is widely distributed all over India and is found associated with a number of host plants. Prevention: Implement crop rotation. Control: Collection and destruction of infested leaves along with the grubs, adult and eggs reduces the pest incidence. ecology and control of insect pests have been studied from Kolhapur region of India. Which may turn yellowish and show burnt patches. A heavy black sooty mould may develop on the honeydew like droplets secreted by mealy bugs. In another study it was confirmed that infestation of stem borer was seen usually in the later stage of crop (Anonymous 2008). Besides the feeding damage, aphids and whitefly also exude honeydew which favours the development of sooty mould. Brinjal Borer; Pod Borer; Rice Stem Borer; Litchi Mite; Rice Leaf Folder; Fruit Fly; Moth and Butterfly. of Zoology, Shivaji University, Kolhapur - 416 004. A short summary of this paper. Among them, the egg parasitoid Trichogramma chilonis Ishii have been demonstrated to be most effective (Krishnamoorthy, 2012) and it was slightly more efficient than Trichogramma evanescens Westwood in parasitizing the egg in test tube and in caged conditions. The book begins with a detail descriptions of insecticides and other chapters related to pest control such as chemosterilants, radiational control, pheromonal control, attractants, repellents, antifedants, neuropeptides, etc. A special emphasis is given on Biological control of pest and classification and applications of pesticides used in sericultural crop protections. interests regarding the publication of this paper. Nymphs and adults suck the cell sap from leaves, affected leaves become yellowish and lower surface are found covered with black insect excreta. A female lays on an average 250 eggs on leaves, shoots or sometimes on fruits. A generation is completed in a period of one month. Spraying with 0.05% monocrotophos 36 WSC or 0.2% carbaryl or dusting with 10% carbaryl 3-4 weeks after transplantation subsequent application 15 days thereafter controls the pest effectively. Different stages of mites are found in colonies covered by white-silky webs on lower surface of leaves. Direct-feeding damage by aphids is rarely severe enough to kill plants. The damaged leaves curl upwards along the margins. Brinjal Solanum melongela L. is an important vegetable crop of subtropics and tropic with fuel, They always found in the leaf folds. Nymphs and adults suck cell sap and white patches appear on leaves. 3. Regular destruction of damage fruits at each harvest in brinjal to reduce the population. vigintioctopunctata (Fab. Pre-infested plants were suspected to induce productions of sec-ondary metabolites as a chemical defense system thus lowering the number of whiteflies on them. The data further reveals that the extreme population of jassid was showed (12.51/leaf) on 24th December. Vegetables are good sources of proteins (peas, beans and garlic), vitamins (tomato, carrot, peas, tomato, garlic, green chillies and cole crops), minerals (drumstick pods) and carbohydrates (leguminous vegetables, methi, potato and sweet potato). Similarly, the least population of A. biguttula biguttula was recorded (0.14/leaf) on 4th March. The maximum predator prey ratio of aphid was recorded (1:56.43) on 19th November and the minimum ratio was showed (1:2.71) on 25th March. The removal of sap creates a lack of vigor in the plant, and aphid saliva is toxic to plants. week of November with 1.45 aphids/sample. When to Use: Use from flowering stage till harvesting stage.

Brinjal Solanum melongena L., Okra Abelmoschus esculentus L., mulberry Morus alba L. and Guava Psidium guajava have been attacked throughout the year. The family Braconidae was dominant over others by the number of individuals (39) parasitizing pest insects. At the initiation of fruiting stage in October, with the shifting of borer infestation from shoots to, Table - 1 : Ecology and control of Brinjal insect pests, best suitable insecticides for control of brinjal fruit, …Table - 1 : Ecology and control of Brinjal insect pests, Table - 2 : Seasonal abundance of insect pests on Brinjal, pest control (Sathe & Oulkar, 2011). The affected plants show the development of galls on the roots. The damage of different insect pests varies from year to year depending upon intensity of insect pest attack [8]. The infestation may lead to fruit drop or the fruits remain on the shoots in a dried and shriveled condition. Sex ratio studies in the parasitoids revealed that the males outnumbered females during the initial period of emergence, whereas at later period the females were more in number. Fruit and shoot borer, Jassids, Whitefly, Aphids, Thrips, Mealybug, are most serious pests from quarantine point of view as these pests may find a place in the pathway of brinjal … throughout the year. ), Urentius sentis Diast., Amrasca bigutulla biguttula Dist., Bemisia tabaci Spraying 0.15% carbaryl/ 0.1 % malathion/Azadirachtin was also found effective against teak pests. nutritional and ayurvedic medicinal value. help in the reduction of nematode population.

The area under cultivation of vegetables stood at 9.542 million hectares. Adults are oval in shape, straw coloured dorsaly and black on the ventral side. Single female produces 8-22 nymphs/day. The jassid inject the toxic substances and suck the cell sap of the leaves and causes 24.45% yield loss [7]. Many of the vegetable crops, such as onion and garlic, possesses high medical value (Harris et al. Aphids Aphids suck cell sap from tender leaf, shoot, flower buds and developing fruits. capitata were evaluated under field during 2003-05. Studies were undertaken to find the natural parasitisation efficiency and population dynamics of Trathala flavoorbitalis Cameron a nonspecific parasitoid of brinjal shoot and fruit borer, Leucinodes orbonalis Guenée. They can also travel for miles … Therefore, the aphid infested the brinjal and increased their population (27.92/leaf) on 21st January, while its decreased population was showed (1.47/leaf) on 25th March. jassid (136.02 per 10 leaves), whitefly (92.88 per 10 leaves), aphid (83.33 per 10 leaves) and brinjal shoot and fruit borer (20.44 male moth per trap-week) and their highest population was observed at 70, 85, 70 and 116 days after transplanting (DAT). Full grown larva is light pink measuring about 12mm long. The first peak incidence of brinjal shoot and fruit borer was 9.15 (shoots) and 42.10% (fruits) in the 32nd and 39th SMW, respectively. These pests can cause damage to both the plant and the fruit. The book is ready notes for graduate and post graduate students of agricultural universities and traditional universities. In addition global climate change also posing a serious threat to crop production where many major diseases become still aggressive and minor diseases becoming major problem. This affect adversely plant growth and yield. The losses may be at field condition (Pre-harvest losses) and at storage (Post-harvest losses). Collection and burning of severely infested plant parts reduces further multiplication of mites. Hence, biopesticides (parasitoids) play a very crucial role in pest control and keeping environment ecofriendly. Nature of damage; It is specific pest of brinjal. damage in brinjal by BSFB was higher in May transplanted (spring) crops than that of July and September transplanted (fall) crops. The data showed that the highest population of whitefly was recorded (17.56/leaf) in the 3rd week of January. Direct feeding damage by A. gossypii on cotton is related to plant growth stage and level of aphid infestation. T. flavoorbitalis was found to be an abundant parasitoid in brinjal ecosystem. 2013). The highest and lowest predator prey ratio was recorded (1:92.25 and 1:0.09) in the 2nd week of November and 1st week of March on jassid.
