ABSTRACT
Research on title the predation ability of Forficula sp. (Dermaptera : Forficulidae) and
Dolichoderus sp. (Hymenoptera : Formicidae) of Brontispa Longissima Gestro.
(Coleoptera : Chrysomelidae) in laboratory aimed to study the predation ability of Forficula sp.
and Dolichoderus sp. of Brontispa longissima Gestro (Coleoptera : Chrysomelidae) in Laboratory.
The experiment design was randomized complete design with 8 treatments and 3 replications.
The tested treatment were larvae and imago of B. longissima, 2 Forficula sp, 2 Dolichoderus sp,
1 Forficula sp and 1 Dolichoderus sp on 10 larvaes/stoples and 2 Forficula sp, 2 Dolichoderus sp,
1 Forficula sp and 1 Dolichoderus sp on 10 imagoes/stoples with. The result showed that
percentage of mortality and the predators behavior. The results showed that the highest percentage
of mortality on P1 (2 Forficula sp. on 10 larvaes/stoples) was 96.67% and the lowest on
P01 (larvae control) was 0% and the result showed that Forficula sp. prey mechanism begins with
the introduction of active antenna movement then using forcep (cerci) capture
Brontispa longissima Gestro and predator prey Dolichoderus sp. way starts with the running
approaching pest predators and prey circling approach as the larvae begins to feed through the body
surface.
Keywords : predation, B. longissima Gestro, percentage mortality
