【Abstract】 Trichophysetis cretacea is an important pest of Jasmine. The bionomics, life history and control methods for this pest were studied. This borer insect had fourteen generations a year in Guangxi and needs 14 to 22 days to complete one generation. The larval stage consists of four instars. The duration of the preoviposition stage is 2 to 3 days, that of the egg stage 2 to 4 days, the larval stage 5 to 10 days, and the pupal stage 5 to 8 days. Generations overlap. Peak occurrence is from June to September. Effective control methods are discussed.更多还原
