Abstract

Experiments were carried out in the field and in the laboratory of the Department of Entomology, Bangladesh Agricultural University during the period from February to August, 2013. Three cucurbitaceous vegetables viz. bitter gourd, ridge gour d and snake gourd were used as test crops. Considering to percent leaf infestation and leaf area consumptions, red pumpkin beetle was found mostly harmful to snake gourd (22.62% and 8.84%, respectively) but least harmful to bitter gourd (3.00% and 1.25%, respectively). On the other hand, Epilachna beetle was found mostly damaging to bitter gourd (46.00% and 21.67% respectively) and least damaging to ridge gourd (11.20% and 5.00%, respectively). Similar to the field experiments, red pumpkin beetle consumed more leaf areas of snake gourd (up to 43.36%) and Epilachna beetle (both adult and grubs) consumed more leaf areas of bitter gourd (up to 91.46%) in the laboratory experiments. Bitter gourd (1.42%) and ridge gourd (0.78% to 41.27%) were least preferable to the red pumpkin beetle and Epilachna beetle, respectively.
