POTENSI ASAP PEMBAKARAN TEMPURUNG KELAPA DALAM PENGENDALIAN HAMA Rhyzopertha dominica F. (COLEOPTERA: BOSTRICHIDAE) PADA GABAH DALAM SIMPANAN

Abstract

ABSTRACT
Utilization of smoke as a fumigant, has long been done to control pests which
attack the material in storage. Rhyzopertha dominica is avprimary pest of rice in
storage. Heavy attack of R. dominica on the rice storage could caused yield losses
about 7% during 6 months. Larvae and imago R. dominica attacking growing
point and the endosperm of seeds, causing serious losses. A research to study
characteristics and effect of smoke burning coconut shell to R. dominica and the
influence of rice germination/viability. The research method used Completely
Randomized Design with fumigation time treatment. Fumigation treatment
consisted of four level (0 hour as a control, 1 hour, 2 hours and 3 hours). Each
treatment consisted of 4 replications. The results showed that smoke from burning
coconut shell can cause mortality to imago of R. dominica, causing low
population of R. dominica, causing eggs damage, mortality to larvae of R.
dominica, fumigation of rice during 1 hour, 2 hours and 3 hours, give no effect on
rice germination, but on rice seedling height and fumigation time of paddy is
effective and efficient for controlling R. dominica is 2 hours.
