“…Soil borne insects viz. white grubs (Holotrichia longipennis, Brahmina spp, Melolontha furcicauda and Oryctes spp), wireworm (Agriotes spp) and cutworm (Agrotis spp); sucking pests including wheat aphid (Schizaphis graminum), green stink bug (Carpocoris spp), aster leafhoppers (Macrosteles quadrillineatus), broad-headed bug (Camptopus lateralis) and oat thrips (Stenothrips graminum) and foliage pests including cereal leaf beetle (Oulema melanopus L.), surface grasshopper (Chrotogonus trachypterus Blanchard), armyworm (Mythimna separata) and gram pod borer (Helicoverpa armigera) appeared as pests in the oats field [11]. Among these M. separata, O. melanopus and H. armigera were major pests [12].…”

Experiment was carried out at farmers field near the Faculty of Agriculture, Wadura, Kashmir, India during 2021-22 to evaluate efficacy of various insecticides and botanicals against cereal leaf beetle Oulema melanopus (L.) (Coleoptera: Chrysomelidae) infesting Rabi Oats (Avena sativa L.) in North Kashmir. Among plant extracts and insecticides evaluated against O. melanopus, Abamectin proved to be most effective in causing huge mortality to grub population with decreasing number of grub were recorded as (24, 21.3, 8.3, 1.6 and 1 %) after 2,4,6,8 and 10 days of spray, respectively during 2021 followed by Thiamethoxam (32.6, 15.3, 8, 0.3%) after 2, 4, 6, 8 ad 10 days of spray. Same trend of results was observed in 2022 and the pooled data. Among tested botanicals viz. neem and Artimesia; Artimesia was effective in declining the grub population with (44, 42, 41, 39 and 37%) after 2, 4, 6,8 and 10 days after spray. Severe infestation has been observed at maturity of crop and keeping in view the use as fodder to cattle it is necessary to inculcate the use of locally available botanicals for better health of cattle during the dearth period of fodder in Kashmir valley. Overall, the marginal farmers might be saved from any untoward by utilization of the bioactive plant extracts in management of this notorious pest.

“…Weather variables like rainfall, temperature, relative humidity and wind speed were found to significantly affect pest numbers [4]. In order to carry out Integrated pest management, the knowledge of pest ecology, information regarding the pest incidence at different growth stages and its relation with weather parameters is necessary [5,6]. The study of seasonal incidence of pests and the period of their peak activity helps in taking prophylactic measures and reduce the curative management practices [7].…”

Field experiment were carried out to study the seasonal incidence of leafhopper, Empoasca flavescens and thrips, Scirtothrips dorsalis and also the influence of weather parameters on the sucking pest population in five castor genotypes i.e., DCH-519, DCH-177, ICH-66, NBCH, PCH-111 during Rabi, 2020-21 at the research farm of RARS, Palem, PJTSAU, Telanagana. The pest population was recorded from 10 random plants and the incidence was observed from 48th standard meterological week and the peak population of sucking pests was observed during 6th to 8th standard week. PCH-111 and NBCH were observed to be more susceptible to sucking pests whereas DCH-519 was least susceptible. The observed pest population is correlated with weather parameters by taking the weather data from the agro meteorological observatory located at RARS, Palem. Correlation studies indicated that all the parameters except max temperature had a negative influence on thrips whereas temperature showed positive influence towards hoppers.
