Anoplophora chinensis (Forster, 1771) (Coleoptera: Cerambycidae) found in Trabzon, Turkey; Its Description, Growth, and Damage

Abstract

Aim of study : Pest situation of A. chinensis, that was firstly recorded in Trabzon, was investigated. Area of study: The study was conducted in Municipal ornamental plants stocking area and lab. Material and Methods: The developmental stages, morphological features and damage size of the insect was investigated in the field and laboratory from June to end of November. Main results: Adults were active from May to the end of August. Adults lived about 30 days. Average body lengths of females and males were 28.6 mm and 25.4 mm, with average antennae lengths of 31.1 and 44.1 mm, respectively. The average antenna length of female are 1,1 times as long as their bodies, and the average antenna of male 1,7 times as long as their bodies. Lenght of larva was measured as 6-7,5 mm in July and 24-37 mm at the end of November. The average length of larval holes in the wood was 3.81 cm before wintering and 11.94 cm at the end of the larval growth. The average volume of larval hole per larva in wood before larval wintering was 4.66 cm 3 , and 21.81 cm 3 at the end of larval growth. The circular exit holes on boles were, on average, 1.04 cm in diameter and at 5.18 (1-16.1) cm above the ground level. The average length of the larval holes in roots was 6.73 (5.2-15.5) cm below the ground level. Research highlights: Larval holes were observed up to 16.1 cm above and 15.5 cm below ground level within the wood. A total of 52 larvae that bored holes into the sapwood of six young trees consumed nearly 27 (26.98) percent of the stemwood, 12 (11.94) cm in length. Trees weakened by larval attack become readily susceptible to wind damage as the proportion of holes in the wood increases.
