    ABSTRACT Name: Akanksha. Id. No: 4858/19 Semester and Year of admission: Ist Sem. 2019-20 Degree: M. Sc. (Ag.) Major: Entomology Department: Entomology Minor: Plant Pathology Name of Advisor: Dr. D.N. Mishra Thesis title: “Efficacy of insecticides against Diamondback Moth (Plutella xylostella Linn.) in cabbage (Brassica oleracea Linn.)” The field experiment entitled “Efficacy of insecticides against Diamondback Moth (Plutella xylostella Linn.) in cabbage (Brassica oleracea Linn.)” was conducted in Randomized Block Design with three replications and seven treatments during Rabi season, 2020-2021 at Crop Research Centre, Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.) 250110. During the trial the larval population of diamondback moth was recorded from November to February (2020- 2021) in all plots. The larval population of DMB reached its peak (7.33 larvae/ 5 plant) at last week of January 2021, (4th standard week) when, the maximum and minimum temperature were 18.8 ℃ and 6.46 °C, respectively with 73.64 per cent relative humidity and 0.0 mm rainfall. The correlation study between the larval population of diamondback moth and weather parameters showed a negative correlation with maximum and minimum temperature (r = -0.847 and -0.664), and positive a association with relative humidity (r = 0.818), and rainfall (r = 0.161). Among all the insecticides Chlorantraniliprole 18.5% SC @ 10g a.i./ ha was most effective in controlling larval population of DMB followed by Spinosad 2.5% SC @ 16g a.i./ ha, Emamectin Benzoate 5% SG 8.75g a.i./ ha, Flubendiamide 39.35 % SC @ 18.24 a.i./ ha, Indoxacarb 14.5% SC @ 35 g/ ha in both the sprays. The Novaluron 10 EC @ 75 g a.i./ ha was found to be least effective, but it was significantly superior over the Untreated plot. Among all insectides the maximum C:B ratio and yield is obtained in plot treated with Chlorantraniliprole 18.5% SC @ 10g a.i./ ha preceded by Flubendiamide 39.35 % SC @ 18.24 a.i/ ha with second-best C: B ratio and second highest yield in the plot treated with Spinosad 2.5% SC @ 16 g /ha and Novaluron 10 EC @ 75 g/ ha has the lowest C:B ratio and yield.

    ABSTRACT Name: N. Preethi ID.No.: 4836 Semester and Year of admission: 1st Semester, 2020-21 Department: Entomology Degree: M. Sc. (Ag.) Entomology Advisor: Dr. Gaje Singh Thesis title : “Field Evaluation of Microbial Insecticides and Insect Growth Regulators against Gram pod borer, Helicoverpa armigera (Hubner) in Chickpea” The present investigation was undertaken to evaluate the microbial insecticides and insect growth regulators against Gram pod borer, Helicoverpa armigera (Hubner) in chickpea. The experiment was conducted in randomized block design with three replications and seven treatments during Rabi, 2020-21 at Crop Research Centre (CRC), SVPUA&T, Meerut-250110 (UP). The seasonal incidence of H. armigera was observed from 52th standard meteorological week up to 14th standard meteorological week. The maximum incidence was observed during 10th standard meteorological week with 24.67 larvae per ten plants. The correlation of gram pod borer larval population was found significant and positive with maximum temperature (r= 0.624) and minimum temperature (r= 0.651) and a non-significant and negative correlation with morning relative humidity (r= -0.642), evening relative humidity (r= -0.615) and rainfall (r= -0.226) during Rabi, 2020-21. Among all the treatments i.e. Bt @ 1.5 Kg/ ha, Ha NPV @ 250 LE / ha, Spinosad 45 SC @ 250 ml/ ha, Emamectin benzoate 1.9 EC @ 500 ml/ ha, Novoluron 10 EC @ 750 ml/ ha and Lufenuron 50 EC @ 500 ml/ ha, the insecticide Spinosad 45 SC @ 250 ml/ ha was found best in reducing the number of H. armigera with minimum of 1.33 and 0.33 larvae per ten plants at 3 and 7 days, respectively after second spray and also found effective with minimum pod infestation of 6.33 per cent. The Emamectin benzoate 1.9 EC @ 500 ml/ ha was second best treatment with 1.67 and 1.00 larvae per ten plants at 3 and 7 days, respectively after second spray and found effective with pod infestation of 7.66 per cent. The treatment Spinosad 45 SC @ 250 ml/ ha was found best with maximum grain yield (21.09 q/ ha) and maximum returns (Rs. 61896.8/ ha) and highest cost benefit ratio (1:12.89) followed by Emamectin benzoate 1.9 EC @ 500 ml/ ha (17.58q/ ha, Rs.42230.2/ ha, 1:10.75) and Novoluron 10 EC @ 750 ml/ ha (16.53 q/ ha, Rs. 33586.4/ ha, 1:10.75).

The lab experiment entitled “Constructions of life table for some bi-voltine hybrids of mulberry silkworm (Bombyx mori Linn.) under lab conditions.” was conducted during Kharif season-2021 at Sericulture Research, Demostration and Training Unit, Department of Entomology, College of Agriculture, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut-250110 (U.P.). Mulberry silkworm, Bombyx mori Linn. race NB4D2 x SH6 required 37 and 40 days to complete its life cycle at control temperature (25±1°C) and room temperature, respectively. There was an initial drop in survivorship (lx) followed by an intermittent steady decline with the long pauses till the formation of adult and sharp decline was observed at adult stage in both the conditions viz., control temperature (25±1°C) as well as room temperature till the end of generation. The data obtained from stage specific life table, the highest apparent mortality 17.58 was recorded at 1st instar larval stage of Bombyx Mori Linn. race NB4D2 x SH6 at control temperature (25±1°C). The summation of all the k-values, 0.30 was recorded at room temperature followed by 0.27 at control temperature (25±1°C). The data obtained from life and fertility table exhibited highest potential fecundity was 331 eggs per female at control temperature (25±1°C) and 290 eggs per female at room temperature. The value of net reproductive rate (R0), intrinsic rate of increase (r), finite rate of increase (λ) were114.33, 0.07, 1.174 at control temperature (25±1°C), respectively much better than the values obtained from room temperature. The mean length of generation (T) and annual rate of increase were 27.66 days, 3.12437874 x 1028 at control temperature (25±1°C), respectively also superior than the values obtained from room temperature.

    DEPARTMENT OF ENTOMOLOGY SARDAR VALLABHBHAI PATEL UNIVERSITY OF AGRICULTURE AND TECHNOLOGY, MEERUT-250110 (U.P.) INDIA Name : LINGUTLA GEETHANJALI, Chairperson : Dr. HEM SINGH I.D. No : PG/A-5396/20 Professor Degree Program : Ph.D. (Entomology) Thesis title: Screening of Mustard Varieties against Mustard aphid, Lipaphis erysimi (Kaltenbach) and its Eco-friendly Management. ABSTRACT An investigation titled “Screening of Mustard Varieties against Mustard aphid, Lipaphis erysimi (Kaltenbach) and its Eco-friendly Management” was carried out in the Crop Research Centre (C.R.C.) of Sardar Vallabh bhai Patel University of Agriculture & Technology, Meerut, U.P. during Rabi, 2021-22 and 2022-23. Out of the twenty varieties screened, two were (PM-30, RH-749) highly resistant, ten were (PM-31, Tarak, Azad, Kranthi, Shivalik, Geetha, Varuna, RH-704, Pusa Jagannath, DRMP) graded into resistant and eight varieties (PM-28, PM-29, PM-22, Urvashi, Pusa Agrani, Pusa Mahak, Pusa Bold, Pusa Jai Kisan) exhibited moderately resistant reaction. Except chlorophyll content of leaves, none of the biophysical parameters (Leaf area Index, No. of branches per plant, No. of siliquae per plant, Pod length (cm), Plant height (cm)) has shown significant correlation with the intensity of aphid infestation. The aphid infested plants have shown reduced chlorophyll content which indicates the reduced rate of photosynthesis. Regarding the Biochemical Parameters, varieties which are having high amount of total phenols and total Glucosinolates have shown less aphid incidence and then resistant reaction. The total protein content too exhibited the same impact on intensity of aphid infestation. The insect-pest complex associated with the mustard crop includes Mustard sawfly, Mustard aphid, Cabbage butterfly, Painted bug and Green stink bug. Abiotic factors particularly temperature and relative humidity has shown significant impact on the insect-pest complex of mustard crop. Except Mustard aphid, the association of remaining pests with the mustard crop was very less but mustard aphid remained long period and reached to peak stage during 8th standard week with maximum aphid population of 121 aphid/plant. On the other hand, coccinellid predators were found from 49th standard week, with the peak population of 12.6 beetle/plant during 10th standard week. Dimethoate @ 625 ml/ha has proven as the best treatment in suppressing aphid population followed by Imidacloprid @ 200 ml/ha and Thiamethoxam @ 50 gm/ha. In case of non-chemical insecticides, Verticillium lecanii @ 1 lit/ha and Neem oil @ 1.5 lit/ha were on par with each other followed by Beauveria bassiana @ 2 kg/ha. ICBR (Incremental Cost Benefit Ratio) was highest (6.28) from Dimethoate @ 625 ml/ha treatment and lowest (2.54) from Beauveria bassiana @ 2 kg/ha. treatment. It was 5.53, 5.77, 3.23 and 3.22 for Imidacloprid @ 200 ml/ha, Thiamethoxam @ 50 gm/ha, Neem oil @ 1.5 lit/ha and Verticillium lecanii @ 1 lit/ha respectively.
