A study was conducted to test the bioefficacy of newer insecticides against red pumpkin beetle, Raphidopalpa foveicollis (Lucas) on major cucurbitaceous vegetables in south east Rajasthan. The summer squash, pumpkin and ridge gourd crops were sprayed with different insecticides thrice at 30, 45 and 60 days after germination. All tested insecticides were found superior to control and provided protection to the crops against red pumpkin beetle. The maximum pest population reduction was observed on seventh day after treatments in all three crops in all three sprays. The betacyfluthrin gave maximum reduction (99.41%) of beetle population followed by carbaryl (85.79%) in summer squash white minimum reduction (57.45%) was observed in neemazol after seven day of first spray. Similar trend of efficacy was observed after second and third spray. Beta-cyfluthrin gave 100 per cent reduction of pest after seven days in all three spray in pumpkin and ridge gourd.
