Abstract
Field trials were conducted to find out the “Population dynamics and
management of red pumpkin beetle, A. foveicollis (Lucas) in cucumber crops during
Kharif 2012 at Horticulture Farm, RCA, Udaipur.
The result of present investigation revealed that red pumpkin beetle, A.
foveicollis (Lucas) occurrence began during 35th SMW (27th August to 2 September).
The peak population of red pumpkin beetle (4.80 beetles/five plant) was observed
during first week of October, 2012. The population of red pumpkin beetle showed
positive correlation with mean temperature but significant negative correlation with
mean relative humidity and rainfall.
Bioefficacy of different insecticides viz., flubendiamide (480 SC),
deltamethrin (10EC), dichlorovos (76 EC), quinalphos (25 EC) and flubendiamide +
deltamethrin (90+60 = 150 SC) was evaluated against the red pumpkin beetle in
Cucumber. Among these, flubendiamide +deltamethrin 90+60=150 SC @ 200 ml/ha
found most effective for the control of red pumpkin beetle as it accounted 88.67 per
cent reduction in beetle population. All the insecticidal treatments investigated were
found effective in controlling pests and did not produce any phytotoxic effect on
cucumber plants. The influence of different insecticides was also observed on the
mean population of natural enemies. All the treatments were proved to be safe to
natural enemies.Among different treatments, three spray of
flubendiamide+deltamethrin 90+60=150 SC @ 200 ml a.i./ha at 15 days interval were
found significantly superior over all the treatment in terms of mean reduction of red
pumpkin beetle and marketable fruit yield. It recorded marketable yield of 505.25
q/ha which was significantly higher than all the treatments. Flubendiamide (480 SC),
deltamethrin (10EC), dichlorovos (76 EC) and quinalphos (25 EC) followed the above
treatment in terms of efficacy.
