| Abstract: | Biological characteristics of Porthesia similis on Polygonum aubertii were studied by incubation and investigation in Lanzhou.The results showed that P.similis had two generations each year and overwinters as larva.The eggs were laid on the back of the leaves and to be hatched within 5~8 days.The larva generally had five instars and usually fed on the tender leaves of fallopia aubertii.When the larva became mature,the larva cocooning and pupate on the back of leaves,the gap of trunk or on the ground.The pup... |
