Assessment of insect diversity and community structure in the sugarcane plantation in Jambi Province

Abstract

Sugarcane can be cultivated in diverse agroecosystems, so it has the potential attack of different pest. The study on the biodiversity of insects in sugarcane plantations at different altitudes has the objective to study the insect community structures that are useful in making decisions in integrated pest control. The study was conducted on sugarcane plantations in the highlands and lowlands areas, i.e Kerinci and Muaro Jambi Regency. The insect sample was identified to morphospecies level. The results showed that the altitude did not affect the diversity of insects in the sugarcane agrosystem, nevertheless the altitude affected the abundance of pests attacked. Interestingly, Sesamia was only found attack the sugarcane in the highlands area. Ants (Hymenoptera) causing hollow stems of plants. The intensity of attacks in the highlands ranges 36 - 76%, while in the lowlands 28 - 40% rate of cell division resulting in bacterial colonization and motility approaching the fungal pathogen.
