Abstract:

Anoplophora chinensis was an important wood borer of Casuarina spp.in protection forest. Mature larvae overwintered in xylem of the beef wood trunk. Pupating of larvae of cerambycid beetle was in middle and last ten days of April. Pupal period was 21～26 d, and the peak period of emergence was in middle and last ten days of May. Pupal period was 25 d at 19.5℃ and it was 21*!d at 21.5℃. Incipient temperature for pupa to develop was at (13.91±0.69)℃, and effective accumulated temperature was (144.04±15.96)d℃. According to changing in form and colour of pupa, all pupa periods could be divided into four period, in each period pupa, srespective morphological character occurred. Adult most liked Melia azedarach as supplying nutrients.A female adult fed on bead tree oviposited 156～198 eggs, on an average 176.4 eggs, Which was 3.14 times that that of female fed on Casuarina spp., and the spawned amount each day was 1.57 times that of the latter. Life span of female taking food on bead tree was 72～110 d, on an average 91.8%; Life span of male was 88～125 d, on an average, 103 d. Life spans of female and male were, respectively, 30.2 d and 40*!d more than that on Casuarina spp.
