The studies revealed that sucking and lepidopteran insect pests were found as major pest in causing significant damage to the crop. The population of whiteflies was observed to be increasing and attained the peak populations (25.20 weekly mean) in 16th SW and 22nd SW with 36.50, respectively. Similarly, the two peaks were also observed in case of citrus psylla in 13th SW with 25.00 and in 22nd SW with 35.0 weekly mean population, respectively. The population of leaf miner and citrus caterpillar also revealed two peaks i.e., in 16th and 22nd SW and 12th and 22nd SW, respectively wherein, overall impact of weather factors on population buildup of leaf miner and caterpillar on citrus were 80.08 and 82.10 per cent, respectively. Besides predatory insects, many promising parasitosis were also recovered from citrus orchards like Pyllids parasitoid Tamarixia radiata; whitefly parasitoids, Enacarsia formosa and Eretmocerus sp.; leaf miner parasitoid, Cirrospilus sp., Citrostichus sp. and pupal parasitoids viz., Pteromalus puparum of citrus butterfly larvae were recorded in field condition in citrus orchard. Evaluation of bio-efficacy of some novel insecticides revealed that Thiamethoxam 25 % WG @ 0.2 ml/lit against citrus psylla, Imidacloprid 17.8 SL @ 0.3 ml/lit against whiteflies and leaf miner and Spinosad 45 SC @ 0.3 g/lit against citrus caterpillar was proved to the superior treatment in controlling the specific insect pests. Therefore, the above three novel pesticides along with promising bio-agents may be recommended against four major insect pests of citrus growers of Jammu regionEnglishThesis
