Addendum of Biological Characters of Adult Agrilus mali Matsumura and Rearing of Larvae
摘要
Abstract
In order to define the biological characters of adult Agrilus mali and to easily control the adult in proper management,adult A.mali and larva were reared in the laboratory to study the sex ratio,lifespan,male and female feeding amount and resistance to starvation of adult,and to qualitatively screen feed for mulation of larva.The results showed that the sex ratio of adult was 1 ∶ 3.4.In the starvation,the average life span of male was 4.7 d,the average life span of female was 6.5 d.The maximal life span of adult was 24 d with average of 14.35 d when feeding with apple leaves.The male could survive for 9-14 d,and the total feeding amount was 212.91 mm2.The female could survive 15-22 d,and the total feeding amount was 279.45 mm-2.The adult total feeding amount accounted for 16％-21％ of an apple leaf.The adult died in 2 h after supplying 48％ chlorpyrifos and 5％ beta-cypermethrin foliar spraying.At 25℃ and 70％ relative humidity,feed A1,A2,B1,B2,C and D were used to rear the larvae,pupation and eclosion occurred successfully in the larvae by feeding A2 and D.The larvae which fed with D could survive to 55 d.The results demonstrated that the adult stage of A.mali had a longer life span and active feeding habit,the foliar spraying method could effectively control the adult,the feed A2 and D could be able to supply the enough energy for A.mali growth from larva to adult.关键词
