Abstract

Sugarcane is one of the most important industrial crops in Thailand. The Sa Kaeo province in the east of Thailand is a crucial source for sugarcane production in the country. The information of insect pest identification is signified in the primary step for the pest management. Therefore, this study was focused on the surveillance of sugarcane insect pests and natural enemies in Sa Kaeo. A study on insect Pest diversity was primarily observed during a field survey on eight districts and conducted in the months of March to November, 2019. The sugarcane insect pests were collected by sweep netting and identified by taxonomic classification. About 31 species of insects belonging to 21 families and 7 orders, were associated with sugarcane crop pest and 11 species comprising 10 families and 5 orders were recovered as natural enemies. The species diversity was in the range of 1.63-2.49 and maximum was revealed in Nong Bon district. The highest species evenness was observed in the field from Khok Pi Kong district (0.59) while, the field of Sa Khwan district was the least (0.34). The Simpson’s Index (D) and Simpson’s Index of Diversity (1 – D) were highest in the field of Ta Yaek district as 0.12 and 0.88, respectively. The lower of those indices were obtained from Ban Klaeng’s field (0.13 and 0.87).
