Two insecticides viz. Cartap hydrochloride 4 G @ 1kg a.i./ha, Fipronil 0.3 G @ 60g a.i./ha and three bio-pesticides viz. Beauveria bassiana @ 10g/lit., Bacillus thuringiensis @ 2g/lit., Metarhizium anisopliae @ 10g/lit. Fipronil 0.3 G soil application after the germination followed by spray with Beauveria bassiana was found to be most effective against okra jassid, as it was recorded overall less jassid populatìon (1.62/plant). The maximum jassid populatìon (2.89/plant) was recorded in Cartap hydrochloride 4 G soil application after the germination. Fipronil 0.3 G soil application after the germination followed by spray with Metarhizium anisopliae was recorded highest fruit yield (89.89q/ha) with benefit cost ratio 1.38:1.00.

The peak activity of Omiodes indicata Fab. (1.67 larvae/mrl) and Spodoptera litura Fab. (1.47 larvae/mrl) were observed during third week of September. Whereas, Chrysodeixis acuta (1.0 larvae/mrl), Anarsia ephippias (0.6 larvae/mrl) and Helicoverpa armigera (0.67 larvae/mrl) were recorded during first week of September, third week of August and fourth week of August, respectively.

Insect pests are the major threats to production and productivity of greenhouse crops worldwide. ... more Insect pests are the major threats to production and productivity of greenhouse crops worldwide. Presence of warm, humid conditions and abundant food under protected structures provide a stable environment and habitat for pest development. Protected cultivation/Greenhouse technology has been in use for crop production for more than fifty countries all over the world. China is believed to have adopted a plastic greenhouse concept to a great extent. Japan, with about 42,000 ha. (hectare) under plastic and glass cover land holdings with shorter growing seasons in Holland and Japan have been the reason behind adopting Protected cultivation /greenhouse for intensive crop production.

They are consumed in various forms i.e., salad (cucumber, gherkins, long melon), sweet (ash gourd, pointed gourd), pickles (gherkins), and deserts (melons).Cucurbits pest management program is to develop a regular scouting plan to gain information on insect pest populations that is used to determine if insecticide applications are needed. There are a large variety of cucurbits most have a few very important pests in common such as beetles, bugs, mites and aphids. Some pests are more specific such as vine borer, which attacks pumpkins and squash. The organic and inorganic system proved to be the most effective and economical approach against cucurbits aphid (Aphis gossypii), leaf eating caterpillar (Diaphania indica), hadda beetle (Epilachna vigintiopunctata) and cucurbit fruit fly (Bactrocera cucurbitae).
