Abstract
Two experiments were conducted to
study the biology of dried fruit beetle (Carpophilus hemipterus L.)
on dried fruits cashew nut in the laboratory of the department of
Entomology, Sher-e-Bangla Agricultural University, Dhaka-1207 during
August, 2016 to January, 2017. Experiments were laid out in a
Completely Randomized Design (CRD). It was revealed that the adult
female laid an average of 52.75±9.26 eggs. The adult insect
completed its life cycle by 16-21 days and the incubation period,
larval period, pupal period and adult longevity of dried fruit beetle
were 2.60 ± 1.21, 8.20 ± 1.06, 3.40 ± 1.32 and 153.60 ± 25.32
days respectively at 23-30 0C temperatures and 68-87% humidity.
Morphometric measurement of different life stages of the beetle was
also recorded during the study period.
