Experiments were carried out to assess some insecticide modules against major insect pests of rice. Each module consists of a basal application of carbofuran 3G @ 1 kg a.i ha-1 at 20 DAT and Rynaxypyr 20 SC @ 30 g a.i ha-1 at 45 DAT except untreated control. All modules differ with each other only in third treatment which was applied in 65 DAT. The third treatment includes: Imidacloprid 17.8 SL @ 27 g a.i ha-1, Pymetrozine 50 WG @ 150 g a.i ha-1, Triflumezopyrim 106 SC @ 27 g a.i ha-1, Buprofezin 25 SC @ 250 g a.i ha-1; Glamore (Imidacloprid 40+Ethiprole 40% w/w) 80 WG @ 100 g a.i. ha-1, Thiacloprid 24 SC @ 60 g a.i ha-1, Azadirachtin 0.03 EC @ 8 g a.i ha-1, Dinotefuran 20 SG@ 40 g a.i ha-1 and untreated control. All the treated plots recorded significantly lower percent of dead heart, white ear- head caused by stem borer and silver shoot caused by gall midge. Module with Pymetrozine 50 WG @ 150 g a.i ha-1 treated plot recorded significantly higher per cent reduction of plant hoppers (>80% over untreated control) and produced higher grain yield (50.75 qha-1) than the other modules. Among the different treated modules the maximum number of spiders was found in Azadirachtin 0.03 EC @ 8 g a.i ha-1 treated module plot followed by other treatments.

Number Of Species

A preliminary survey of major insect pests on rice was carried out during the Kharif season of 2020, from June 2020 to October 2020 in selected plots of rice around Panvel, Navi Mumbai, India. 16 species of insect pests representing 03 orders, 06 families and 15 genera were observed. Number of species of insect pests distributed in each family reveals that 09 species belongs to family Acrididae, 03 species to Erebidae and 1 species each to Crambidae, Nymphalidae, Libellulidae and Pyrgomorphidae. Family Acrididae shows the highest percent representation of species (56.25%) followed by Erebidae (18.75%) and Crambidae, Nymphalidae, Libellulidae and Pyrgomorphidae (6.25%). Results of the preset study indicates that larval forms and adults of grasshoppers, dragon flies and bugs are the major insect pests of paddy at various growth stages. It is recommended that preventive measures like frequent dusting and spraying of insecticides and de-weeding of the crop will control the infestation by insect pests and will improve the yield of rice. Since no earlier reports are available, data presented here can be taken as a baseline data on major insect pests of rice in Panvel region, Navi Mumbai, India
