| Summary: | Oil palm Lepidopteran species were reported to attack oil palm, which caused substantial crop
loss. The biological control approach is mainly the encouragement of natural enemies’
population build-up, including insect predators, which will result in the natural suppression of
the Lepidopteran pest population. There is insufficient evidence on the preference of insect
predator, Callimerus arcufer Chalpin (Coleoptera: Cleridae) against Lepidopteran leaf
defoliators, hence this study determined the prey species preference of C. arcufer. The
experiment was conducted through choice and non-choice prey acceptability by C. arcufer at
constant densities of different Lepidopteran prey species. When the predator was not given
choices of prey, the predator consumed all prey species given, with an insignificant difference
in percentage consumed. The predator, however, has a significantly higher preference towards
both bagworm species, Metisa plana, and Pteroma pendula compared to other Lepidopteran
species tested, implying that C. arcufer could be an important predator species for oil palm
bagworm, and could sustain in the environment when its main food source is inadequate. |
