Impacts of chipping on surrogates for the longhorned beetle Anoplophora glabripennis (Coleoptera: Cerambycidae) in logs.

摘要: As part of the eradication program for recent introductions longhorned beetle Anoplophora glabripennis (Motschulsky) in United States, wood from infested trees is chipped and incinerated. Two tests were conducted to evaluate efficiency chipping on survival beetle. In first test, plastic worms used as surrogates larvae Plastic different sizes placed holes drilled logs sugar maple, Acer saccharum Marsh. a second addition worms, we instars pupae gypsy moth, Lymantria dispar (L.) (Lepidoptera: Lymantriidae); Phyllophaga annina Lewis (Coleoptera: Scarabaeidae); an unidentified weevil Curculionidae). Although did not result obvious damage all it kill insects maple logs. The overall recovery rate (percent recovered) was 96% (1997) 71 98% 10 40 mm long (1998) respectively. Logistic regression analysis data experiment indicates that larger receive more severe damage. Size have significant effect level received by worms. All recovered severely damaged after could determine rates. Results two indicate without incineration resulting chips provides highly effective method destroying inhabiting insect pests such A. glabripennis. elimination saves considerable resources while effectively eliminating risks associated with movements containing living wood-boring insects.
