Abstract:
Hadda beetle Epilachna vigintioctopunctata Fab is one of the fundamental pest of backbone gourd in hill region of Chhattisgarh. It commonly known as epilachna beetle or spotted leaf-consuming beetle that one of the severe detrimental pest of cucurbit vegetation, especially backbone gourd. Assessment of the seasonal incidence of hadda beetle allows in knowledge the populace fluctuation of those pests and consequently their effective management. A field survey became achieved at weekly c programming language, each the stages of larvae (grubs) and adults of hadda beetle populace happened patiently all through whole crop growing season in Kharif at some point of 2019-20 in Ambikapur C.G. The height of (6.4 beetles/plant) populations and (thirteen. Forty seven leaf damage) percentage had been located during remaining week of August (35th SMW). The least (0.Forty beetle/plant) populations with leaf harm percentage of (three. 07%) were determined at some point of first week of October (fortieth SMW). The correlations between hadda beetle and abiotic elements shows that non-enormous and superb correlation. At the same time as, the leaf harm percent and the abiotic elements indicates non-extensively fantastic correlation with the most temperature, minimum temperature and morning relative humidity and rainfall except night relative humidity.
