ThesisItem Open Access Studies on biology, chemical control and residue of insecticides against citrus butterfly papilio demoleus (Linnaeus) on kinnow mandarin (Citrus nobilis × citrus deliciosa)(CCSHAU, 2018) Meenakshi Devi; Jaglan, R.S.Studies on biology, chemical control and residue of insecticides against citrus butterfly, Papilio demoleus (Linnaeus), on Kinnow mandarin (Citrus nobilis × Citrus deliciosa) were conducted during 2016 and 2017 in the Department of Entomology, CCS Haryana Agricultural University, Hisar, India. Biology of the insect was studied at room temperature conditions (temperature 29-35°C; RH 60-75%). The results revealed that pre-oviposition, oviposition and post-oviposition period averaged 1.30 0.48, 4.20 0.79 and 2.44 0.45 days, respectively. A single female laid 100.9 4.04 eggs which hatched in 4.24±0.69 days. The mean duration of 1st, 2nd, 3rd, 4th and 5th larval instar was 2.7±0.48, 2.6±0.52, 2.9±0.31, 3.2±0.42 and 5.2±0.42 days, respectively. The mean longevity of male was 4.07±0.18 days and that of female as 6.84±0.19 days. Morphometric studies on P. demoleus revealed that the eggs measured 1.01±0.05 mm in diameter. Average body lengths of 1st, 2nd, 3rd, 4th and 5th instar larvae was 5.30±0.38, 9.18±0.11, 14.00±0.53, 26.21±2.02 and 45.00±2.62 mm, respectively. The average wingspan and body length measured 90.45±1.59 and 27.35±0.97 mm in male, while 90.93±2.13 and 28.58±1.24 mm in female, respectively. Peak incident of Papilio demoleus larvae and leaf infestation were observed 39th Standard Meteorological Weeks (SMW), i.e., in September during 2016 and 2017. The larval population and per cent leaf infestation had significant negative correlation with maximum temperature and significant positive correlation with relative humidity. Oviposition preference indicated that among the four host plants maximum numbers of eggs were laid on lemon (21.80 eggs/plant), while minimum on grapefruit (4.28 eggs/plant). The food consumption index of first to fifth larval instar was maximum on lemon plant (66.535 g/larvae) and minimum on grapefruit (42.037 g/larvae). Similarly, RGR was observed maximum on lemon (1.864 0.147) and minimum on grapefruit (0.465 0.046). Results of pooled mean of 2016 and 2017 showed that the lowest larval population was found in plants sprayed with quinalphos 25EC (i.e., 5.33 to 2.00 /plant) after first and second spray, while highest larval population was observed in Bacillus thuringiensis var. kurstaki (i.e., 8.79 /plant) after first spray and 5.17 larvae/plant in nimbecidine 0.03% after second spray. The residues of malathion (625 and 1250 g a.i. ha-1), imidacloprid (17.8 and 35.6 g a.i. ha-1) and thiamethoxam (25 and 50 g a.i. ha-1) in Kinnow peel and juice were determined at different time intervals, i.e., 0 (two hour after spray), 1, 3, 5, 7, 10, 15 and 30 days after first and second spray. The average residues of malathion (0.047 and 0.096 μg g-1), imidacloprid (0.54 and 0.95 μg g-1) and thiamethoxam (0.38 and 0.62 μg g-1) at both doses in Kinnow peel, while in juice the average residues of malathion, imidacloprid and thiamethoxam were 0.012, 0.12 and 0.07 μg ml-1 at recommended dose and 0.025, 0.19 and 0.1 μg ml-1 at double the recommended dose. The half-life values at single and double doses were 4.2 and 5.2 days for malathion, 3.47 and 3.71 days for imidacloprid and 3.6 and 4.2 days for thiamethoxam. The residue level of malathion were found below MRL on 0 day in Kinnow peel and juice, whereas imidacloprid on 3 day at double dose and thiamethoxam on 3 and 5 days at single and double dose in Kinnow peel.ThesisItem Open Access Effect of different management practices against major insect pests of cotton(CCSHAU, 2018) Suman Devi; Pala RamThe present study was conducted at Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana (India). Effect of different management practices such as sowing time, intercropping, evaluation of ecofriendly practices such as use of neem-based insecticides, release of Trichogramma chilonis Ishii etc. were studied against major insect-pests of cotton during 2016 and 2017. In both the varieties, HD-432 (desi) and H-1098i (American), the population of sucking insect pests namely, Amrasca biguttula biguttula Ishida, Thrips tabaci Linderman and Bemisia tabaci Gennadius and incidence of bollworms namely, Earias species, Helicoverpa armigera Hubner and Pectinophora gossypiella Saunders was high in late sown cotton as compared to early sown cotton. During 2016 and 2017, the minimum incidence of bollworms (Earias species and H. armigera, combined) in green fruiting bodies was recorded in treatment T2 (spinosad 45 SC) (10.09% and 8.10%, respectively) which was at par with T3 (spinosad 45 SC alternated with nimbecidine 0.03 % azadirachtin) (10.13% and 9.14%, respectively), T1 (nimbecidine 0.03 % azadirachtin) (12.24% and 10.85%, respectively) and T6 (cotton-sesame intercropping +release of T. chilonis adults alternated with nimbecidine0.03 % azadirachtin) (10.14% and 8.81%, respectively). During 2016 and 2017, on green bolls basis, minimum incidence of P. Gossypiella was recorded in T2 (spinosad 45 SC) (2.67% and 2.00%, respectively) and it was at par with T3 (spinosad 45 SC alternated with nimbecidine 0.03 % azadirachtin) (3.11% and 2.55%, respectively) and T6 (intercropping cotton-sesame+release of T. chilonis adults alternated with nimbecidine 0.03 % azadirachtin) (2.89% and 2.53%, respectively). Intercropping cotton with different crops was found to have significant effect in reducing the population/incidence of major insect pests in cotton crop. The lowest population of sucking insect pests was found in cotton intercropped with bajra and sorghum as border crop and highest was in sole cotton. Lowest incidence of bollworms was found in cotton intercropped with sesame and highest in sole cotton. Intercropping cotton with crops like sesame, pigeonpea, sorghum and bajra enhanced the population of natural enemies in cotton crop. The results of the present study may be useful in managing insect pests in cotton based organic farming systems.ThesisItem Open Access Seasonal incidence and management of greater wax moth, Galleria mellonella linnaeus in apis mellifera L. colonies and stored combs(CCSHAU, 2018) Panwar, Lalita; Yogesh KumarThe investigation entitled “Seasonal incidence and management of Greater wax moth, Galleria mellonella Linnaeus in Apis mellifera L. colonies and stored combs” was carried out at Research farm, Apiary and Apiculture Laboratory of the Department of Entomology, Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana (India). The population of wax moth (larval, pupal as well as adult) varied during different months during two years study. During both the years, population started increasing from April and increased till July; thereafter (from August) the population started declining and declined till March. In colonies with 4, 6, 8 and 10 frame bee strength, the maximum incidence was noticed in July. Colonies with frame bee strength had more number of larvae, pupae and adult followed by 6, 8 and 10 frame bee colonies. During both the years (2015-16 and 2016-17), the comb area damaged by G. Mellonella in different bee strength colonies started increasing in April and increased till July. From August, the damaged area started decreasing and reached to lowest in March. Maximum comb damage was recorded in July. The cumulative comb area damaged per frame in stored combs increased with the passege of storage time from June to October. Cumulative comb area damaged per frame was maximum when ten combs were stored in a hive body followed by 9, 8 and 7 combs. Larval, pupal and adult populaion in stored combs increase with the passege of storage time from June to October. Larval, pupal and adult populaion was highest when ten combs were stored in a hive body followed by 9, 8 and 7 combs. Among the 25 plant extracts tested against Galleria mellonella in laboratory; 14 were found effective. Among the 14 effective extract, Plantago psyllium husk extract was most effective followed by Hordeum sativum leaves, Linum usitatissimum seed and Raphanus sativus stem, H. sativum stem and R. sativus leaves, Vicia sativa leaves, Cucurbita moschata seed, L. usitatissimum leaves, Cicer arietinum leaves, C. moschata leaves, V. sativa stem, C. arietinum stem and Phaseolus vulgaris leaves (least effective). Among the different chemical and non chemical measures tested for management of greater wax moth in stored combs; the most effective was the low temperature treatment (-15°C, -10°C) followe by low temperature treatment (-5°C and 0°C), aluminium phosphide fumigation, Bt spray, separation of combs with newspapers, NSKE spray, formic acid spray, acetic acid spray, hive chamber separation with newspaper, neem oil spray and broadcasting neem leaves powder.ThesisItem Open Access Studies on the incidence of major insect pests of cotton in relation to morpho-biochemical and abiotic parameters and their management(CCSHAU, 2018) Meenu; Dahiya, K.K.The present study was conducted at Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana (India). Present investigations revealed that the sucking pests (whitefly, leafhopper, thrips) remained active throughout the crop season with little differences among them. It was observed that the sucking pests remained active from 25th to 41st standard meteorological weeks (SMW i.e., June to October) during kharif 2016 and 2017.The data on the population/incidence of cotton whitefly revealed that whitefly did not crossed it's economic threshold level on all the 6 genotypes of cotton during kharif 2016 while it crossed the economic threshold level during kharif 2017 in all the 6 cotton genotypes. The maximum adult population of whitefly was recorded at 32nd SMW during both the kharif seasons of 2016 and 2017. The maximum mean incidence was recorded in RCH-650 BGII during 2016 and 2017. Mean leafhopper population, on all the six genotypes was ranged from 2.02-5.35 and 3.16-5.33 nymphs/leaf during 2016 and 2017, respectively. During 2016, the peaks were observed on 27th and 29th SMW, while peaks were recorded during 2015 in 26th and 29th SMW. Genotype HD-432 had 2.12 and genotype AAH-1 had 3.32 nymphs/leaf during 2016 and 2017, respectively. The thrips population was commenced at 25th SMW during 2016 and 2017, respectively. The peak incidence of thrips population was recorded on 33rd and 31st during 2016 and 2017, respectively. All the sucking pests’ population was higher in Bt hybrids. Peak of natural enemies was observed in 32nd SMW during 2016 and 2017. Minimum bollworms infestation was recorded in RCH-650 BGII during 2016 and 2017. Whitefly population was significantly and negatively correlated with rainfall, leafhopper population was significant and positively correlated with rainfall, thrips population was positively and significantly correlated with sunshine hours and bollworms population was negative and significant correlated with minimum temperature, RH(e) and wind speed during 2016. During 2017, whitefly and thrips significantly and negatively correlated with rainfall. Bollworms population was negatively and significantly correlated with minimum temperature, RH(e) and wind speed. Whitefly and thrips population showed significant and positive correlation with sugar content of leaves and crude protein in cotton seeds while leafhopper showed negative and significant correlation with sugar content of fruiting bodies. Bollworms had positive and significant correlation with crude protein in cotton seeds. Pyriproxyfen, imidacloprid and difenthiuron were found to be most effective insecticides for managing sucking pests while, botanicals were found to be comparatively safer to the natural enemies population.ThesisItem Open Access Relationship of cotton leaf curl virus with its vector, Bemisia tabaci (Gennadius)(Department of College of Basic Sciences and Entomology Punjab Agricultural University Ludhiana, 2002) Singh, Rajinder; Singh, LabhThesisItem Open Access Taxonomic investigations on Nocluidac (Lcpidoptctil) of hisar (Haryana)(College of Agriculture Chaudhary Charan Singh Haryana Agricultural University Hisar, 1999) Kumar, Rishi; Singh, Sucheta KThesisItem Open Access Studies on the role of bio-control agents in the population suppression of mustard aphid, Lipaphis erysimi (I\alt.) on mustard(College of Agriculture Chaudhary Charan Singh Haryana Agricultural University Hisar, 1993) Singh, Dilbag; Singh, harbirThesisItem Open Access Studies on biology and control of root borer (Emmalocera depressella swinhoe) in sugarcane crop(College of Agriculture Chaudhary Charan Singh Haryana Agricultural University Hisar, 1992) Singh, Man; Chhillar, B.
