    (ANDUAT, kumarganj, Ayodhya, 2021-07-30) Kumar, Punit; Chandra, Umesh
    The present studies on the “Evaluation of different traps and lures for management of fruit fly on pumpkin crop ” were conducted in the Department of Entomology, Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya, during 2020-21. Significant variation in occurrence of the fruitfly was recorded during the period of investigation. Trapping of fruit fly was started from 9 SMW and continued up to 25 SMW by using sex attractant, cuelure and methyl eugenol . Incidence of B. zonata and B.dorsalis, was high (48.75 fruit flies/trap/week) and (38.41 fruit flies/trap/week) respectively on 21 SMW caught by methyl eugenol and the incidence of B. cucurbiteae and B.tau, was high (33.41fruit flies/trap/week) and (18.00 fruit flies/trap/week) respectively on 20 SMW caught through cue lure. Correlation between mean population of B. zonata, B.dorsalis showed highly significant positive correlation with minimum temperature and maximum temperature, while the relative humidity showed significantly with negative correlation and rainfall showed non significantly negative correlation respectively and B. cucurbiteae , B. tau population showed non-significantly positive correlation with minimum temperature and significantly positive correlation with maximum temperature however it was significantly negative correlated with relative humidity and non-significantly negative correlated with rainfall respectively in Zaid season of 2020. In the study of efficacy of methyl eugenol and cue lure found that highly capturable and effective sandard dose was Methyl eugenol+ malathion (1.5 ml +2ml) caught 69.39 fruitflies (Bactrocera dorsalis + Bactrocera zonata) and cuelure+ malathion (2ml+2ml) standard dose caught 19.92 fruitflies (Bactrocera cucurbiteae + Bactrocera tau).In the study of life cycle of fruitfly pre-oviposition period, oviposition period, fecundity number of egg/female/life, incubation period (hour), larval period, pupal period, male longevity, female longevity was recarded 13 ±2 days,18.5 ±5 days, 227.5 ±27.5, 1.25 ±0.25 hours , 12.5 ±0.5 days, 9 ±1 days, 18.5 ±1.5 days and 24.5 ±3.5 days respectively. In the study of yield estimation trapping with cuelure+ malathion (2ml+2ml) standard dose given highest yield (236 q/ha) and cast benefit ratio (1:65.0).

    (ANDUAT, Kumarganj, Ayodhya, 2021-07-30) Gokaran, ..; Singh, R.B.
    The present investigations were conducted at Student's Instructional Farm A.N.D.U.A. & T. Kumarganj, Ayodhya, during Rabi season, 2020-21 with the title entitled “Screening of chickpea germplasm and evaluation of insecticides against chickpea pod borer (Helicoverpa armigera Hub.)”. Chickpea (Cicer arietinum L.) is one of the most important leguminous crop and is extensively cultivated in dry and rain-fed areas of the world. Bengal gram is a cheap and important source of protein for those people who cannot afford animal protein or who are largely vegetarian. Chickpea is an important Rabi pulse crop of India and has been considered as “king of pulses” . In India, the total area under chickpea is 106 Lha with the production of > 111 Lt. with productivity 1056 kg/ha. MP has contributed a significant 34% of the total gram area and 41% of total gram production in the country. Out of 30 germplasm screened against H. armigera twenty germplasm ere tolerant viz. NDG 15-9, Vijay, GCP-105, BG-372, NDG 15-5, IPC 2004-52, PDG 84-16, RSG-880, NDG 16-2, NDG 16-1,DCP 92-3, NDG 15-3, NDG 15-8, Vaibhav, NDG 15-7,SAKI 9516, NDG 15-6, PBC-503, L-550 and Pusa 362, ten were moderate tolerant viz. Pant G-186, NDG 98-3, JG-315, Phule G-5, Rajash, JAKI-9218, NDG 15-10, D-19, NDG 16-3, Radhe and remaining 2 germplasm(NDG 15-4, Udai) were susceptible. Field evaluation of insecticides against gram pod borer (H. armigera) was carried out by using 7 insecticides, Out of them maximum mortality observed in Emamectin benzoate 5%SG (85.83%) followed by Flubendiamide 39.35% SC (74.90%), indoxacarb 14.5% (62.54%), Spinoturum 11.7% (62.54%), Spinosad 45% SC (55.66%), Azadiractin 1% SC (50.18%) and Neem oil (44.33%). The highest cost: benefit ratio (1:12.31) was obtained from Emamectin benzoate 5%SG @ 220ml/ha.

    Studies on comparative biology of rice moth, Corcyra cephalonica (Stainton) on different diets & their effects of eggs on parasitization by Trichogramma chilonis (Ishii)
    (ANDUAT, Kumarganj, Ayodhya, 2021-07-30) Chaudhari, Akash Kumar; Chandra, Umesh
    The rice moth, Corcyra cephalonica (Stainton) is one of the most important host insects used for mass production of many predators and parasitoid. The present investigation was conducted at the Biological Control Laboratory, Department of Entomology, Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya, during the year 2020-21. To determining the efficient rearing media for rearing Corcyra cephalonica, nine treatments of different combination with grains and fortified with yeast, protinex and groundnut were used for rearing of C. cephalonica. Among different diets combination, the diet maize 95% + yeast 5% was obtained maximum fecundity (320 eggs), oviposition period (4.6 days) and minimum total developmental period of male and female (55.80 and 56.90 days). The minimum fecundity (190.60 eggs), oviposition period (3.1 days) and longest total developmental periods of male (64.20 days) and female (64.90 days) were found on treatment rice 100%. The different food material also affected the per cent parasitization on the eggs of C. cephalonica by eggs parasitoid Trichogramma chilonis. The maximum per cent parasitization done when host eggs reared on maize 95% + yeast 5% (78%) followed by rice 95% + groundnut 5% (74%). The minimum parasitism was obtained (51%) when reared on paddy 100%. The effect of different diets of trichocard on per cent fruit damage by Helicoverpa armigera on tomato crops. The minimum fruit infestation (1%) observed when diets maize 95% + yeast 5% was used three times release at 15 days interval 5 to 7 days after release. The obtained results provide on the different diets, maize 95% + yeast 5% diet was most suitable for mass rearing of C. cephalonica for the production of large scale and use of high nutrient media for maximum per cent parasitization by egg parasitoids which are also suitable for the control fruit borer in tomato crops.

    The present studies on the “Bioefficacy of seed protectants against pulse beetle in stored pigeon pea [Cajanus cajan (L.) Millsp.]” were conducted under ambient condition in the Department of Entomology, Acharya Narendra Deva university of Agriculture & Technology, Kumarganj, Ayodhya, during 2020-21.The seven seed protectants viz.,Spinetoram (Delegate 11.7%SC) @17ml/kg seed, Flupyradifurone (Sivanto prime 17.09 %SL) @0.02ml/kgseed,Emamectin benzoate (EM -1 5%SG) @40.0mg/kgseed,Neem oil @5ml/kg seed, Dry Neem Leaf@ 5ml/kg seed, Azadirachtin (Neemoz gold 1% EC) @ 5ml/kg seed, Deltamethrin (Decis2.8% EC) @ 0.04ml/kg seed were evaluated against pulse beetle, Callosobruchus Chinensis (L.) in pigeon pea during the investigation. Among testedseed protectants the Emamectin benzoate 5 SG @ 40.0 ml/kg seed,Spinetoram 11.7 SC @ 17 ml/kg seed and Neemoz Gold 1% EC @ 5 ml/kgseed was found most effective as seed protectants with least seed damage and weight loss with maximum germination per cent and vigour of pigeon pea seed up to 6 months of storage which able to maintain the IMSCS level. Per cent seed moisture was increased with increase in storage period. The seed damage and seed weight loss & qualitative loss (Germination, Vigour and moisture content) of pigeon pea seed were increased with increased period of storage. Thus, the present studies clearly revealed that Emamectin benzoate 5 SG @ 40.0 ml/kg seed, Spinetoram 11.7 SC @ 17ml/kg seed and Neemoz Gold 1% EC @ 5ml/kgseed as botanical seed protectants may be used for protecting the seed of pigeon pea against pulse beetle, C. Chinensisfor long period of storage (up to 6 months) during ambient storage.

    The present experiment entitled “Management of insect pest of complex of tomato with combination insecticides” revealed that the incidence of whitefly, Jassid, serpentine leaf miner and tomato fruit borer initiated after transplanting and persist till harvesting. The highest incidence of Whitefly was observed on tomato crop at 1st SMW (7.13/three leaves) and lowest 8th SMW (0.46/three leaves), Jassid 52th SMW(8.30/three leaves) and 8th SMW(0.03/three leaves). The highest incidence of Serpentine leaf miner at 1st SMW (7.10 mines/plant) and lowest 8th SMW (0.60 mines/plant) and Helicoverpa armigera at 4th SMW (3.50 larvae/plant) and 48th SMW (0.20 larvae /plant). Maximum and minimum temperature showed that negative non-significant correlation and morning relative humidity with whitefly, while the evening relative humidity, wind speed, sunshine showed that positive non-significant correlation with whitefly. the Jassid population showed negative significant correlation with maximum and minimum temperature, morning relative humidity and positive non-significant correlation with evening relative humidity, wind speed and sunshine. The serpentine leaf miner population showed the negative non-significant correlation with maximum and minimum temperature, morning relative humidity and positive non-significant correlation with evening relative humidity, wind speed and sunshine. The H. armigera showed the negative highly significant with maximum and minimum temperature, positive highly significant with evening relative humidity and positive non-significant correlation with morning relative humidity, wend speed and negative non-significant correlation with sunshine. Among the efficacy of certain combination insecticides, the treatment Betacyfluthrin 8.49% +Imidacloprid 19.81% OD @400ml/ha was observed most effective against whitefly, Jassid and serpentine leaf miner and least effective was Chlorpyriphos 50%+Cypermethrin5%EC@ 1000ml/ha against whitefly, Profenofos 40%+Cypermethrin 4%EC @1250ml/ha against Jassid and Triazophos 35%+ Deltamethrin 1% EC @ 1000ml/ha was least effective against serpentine leaf miner. The Chlorantraniliprole 10%+ Lambda cyhalothrin 5% ZC @ 250ml/ha was most effective against larval population and least effective was found Triazophos 35%+ Deltamehtrin1 % EC @ 100ml/ha. Followed by Imidacloprid40%+Fipronil40% WG @500g/ha, Imidacloprid 40%+Ethiprole 40% WG @ 500g/ha. The maximum yield 203.41 q/ha was found in Betacyfluthrin 8.49% +Imidacloprid 19.81% OD @400ml/ha and minimum yield 163.17 q/ha in Triazophos 35%+ Deltramethrin1% EC @ 1000ml/ha. The cost-benefit ratio 1:19.31 was highest recorded in Betacyfluthrin 8.49% +Imidacloprid 19.81% OD @400ml/ha and lowest 1:3.12 in Imidacloprid 40%+Ethiprole 40% WG @ 500g/ha.
