| dc.description.abstract | The study was conducted to evaluate the efficacy of six different plant extracts for their
anti-ovipositional and repellent effects against cucurbit fruit fly, Bactrocera cucurbitae
(Coq.) in the research laboratory of the Department of Entomology, HSTU, Dinajpur,
during July to December 2016. Anti-ovipositional and repellent effects of the plant
extracts were evaluated with three different solvents (water, methanol and acetone). The
results of the present study indicated that all the plant extracts had the repellent and antiovipositional effects against B. cucurbitae that inhibited progeny development. The order
of toxicity of the plant extracts based on repellency and anti-oviposition were found as
tobacco > neem > water pepper > castor > bullock‟s heart > eucalyptus. Among the
tested extracts it was found that no progeny (larvae and pupae recovery, and adult
emergence) were developed at 4.0% and 5.0% concentrations. The highest number of
progeny develoment (22.22 in larvae, pupae and adult emergence) was found in
untreated control treatment. However, progeny recovery, percent repellency and antioviposition were found acted as dose dependent manner where percent repellency and
ovipositional deterrence was decreased with the decreased doses of plant extracts. The
highest repellency (60.44%) and anti-oviposition (89.43%) were found in water pepper
whereas the lowest in neem (41.88 and 68.64%, respectively) plant extracts. It is evident
from the results that at all plant extracts treatment caused a remarkable decrease in adult
settled, larvae and pupae recovery, and adult emergence as compared with control. | en_US |
