    SEASONAL INCIDENCE, DISTRIBUTION PATTERNS OF INSECT PEST COMPLEX OF SESAME AND THEIR MANAGEMENT WITH CERTAIN INSECTICIDES
    (Acharya N.G. Ranga Agricultural University, 2017) IMMANUEL CHETHAN PREMDAS, M; HARI PRASAD, K.V.
    Field studies on seasonal incidence, distribution patterns of insect pest complex of sesame and their management with certain insecticides were carried out during summer 2017 at wet land farm, S.V. Agricultural college, Tirupati. Sesame crop (var., YLM-66) was sown two times at fortnightly intervals i.e., on 03-01-2017 and 17-01-2017 to assess the seasonal incidence and distribution patterns of different insect pests. Trial on evaluation of insecticides against sesame pests was sown on March 7th 2017. High incidence of leaf webber, Antigastra catalaunalis larvae was noticed in 2nd week of Febrauary at 40 DAS in 1st sowing and 2nd week of Febrauary at 26 DAS in 2nd sowing. Peak infestation of leaf webber, A. catalaunalis in terms of symptoms of infestation was observed in 2nd week of Febrauary at 40 DAS in 1st sowing and 3rd week of February at 33 DAS in 2 nd sowing. Incidence of hawk moth, Acherontia styx larvae was high during 2 nd week of Febrauary at 40 DAS in 1st sowing and 2nd week of Febrauary at 26 DAS in 2nd sowing. Peak infestation of hawk moth, A. styx in terms of symptoms of infestation was observed in 2nd week of Febrauary at 40 DAS in 1 st sowing and 3rd week of February at 33 DAS in 2nd sowing. Peak infestation of ash weevil, Myllocerus undecimpustulatus in terms of symptoms of infestation was observed in 2nd week of Febrauary at 40 DAS in 1st sowing and 2 nd week of February at 33 DAS in 2nd sowing. Peak infestation of gall fly, Asphondylia sesami in terms of symptoms of infestation was recorded in 3rd xvi week of March at 75 DAS in 1st sowing and 1st week of April at 75 DAS in 2nd sowing. High incidence of leafhopper, Orosius albicinctus nymphs was noticed in 2nd week of Febrauary at 40 DAS in 1st sowing and 2nd week of Febrauary at 26 DAS in 2nd sowing. Incidence of aphid, Aphis gossypii was high in 2nd week of Febrauary at 40 DAS in 1st sowing and 2nd week of Febrauary at 26 DAS in 2 nd sowing. The incidence of leaf webber, A. catalaunalis and hawk moth, A. styx, in terms of larvae and symptoms of infestation was negatively correlated with mean maximum / minimum temperature and evaporation during summer 2017. The correlation was negative and significant between ash weevil, M. undecimpustulatus symptoms of infestation for mean maximum / minimum temperature and evaporation in 1st sowing. Ash weevil, M. undecimpustulatus and gall fly, A. sesami in terms of symptoms of infestation was positively correlated with evaporation in 2nd sowing. Gall fly, A. sesami symptoms of infestation was positively correlated with no. of rainy days in 2nd sowing. Leafhopper, O. albicinctus nymphs exhibited negative correlation with minimum temperature and positive correlation with bright sunshine hours in 1st sowing. Aphid, Aphis gossypii exhibited negative correlation with minimum temperature in 1st sowing. No significant correlation was found between aphids, A. gossypii incidence and meteorological parameters in 2nd sowing. Studies on distribution patterns revealed that larvae of leaf webber, A. catalaunalis, hawk moth, A. styx exhibited a uniform distribution at various stages of crop growth, viz., early vegetative stage, peak vegetative stage, flowering stage, pod formation stage. Ash weevil, M. undecimpustulatus symptoms of infestation also showed an uniform distribution pattern at early vegetative stage, peak vegetative stage while gall fly, A. sesami symptoms exhibited uniform distribution at pod formation stage only. Both the sucking insect pests i.e., leafhopper, O. albicinctus (nymphs) and aphids, A. gossypii exhibited clumped or aggregate distribution though it is more conspicuous in case of aphids. Results on efficacy of certain insecticides against leaf webber, A. catalaunalis, hawk moth, A. styx, leafhopper, O. albicinctus and aphid, A. gossypii revealed that the chemical treatment with chlorantraniliprole @ 0.3 ml L -1 was found to be highly effective against leaf webber, A. catalaunalis. Lambda cyhalothrin @ 1 ml L-1 was superior against hawk moth, A. styx where as pymetrozine @ 0.4 g/L was performed highly against leafhoppers, O. albicinctus and aphids, A. gossypi
