| Aphrodisium faldermannii rufiventris Gressit belongs to the Coleoptera, Polyphaga, Chrysomeloidea, Cerambycidae, Cerambycinae, Aphrodisium Thomson.Distribute the Fujian, Guangxi, Szechwan.The main host has the Castanopsis fabri, C.eryei, Altingia chinensis...etc. the broad-leaved brood tree.That insect mainly is to bore into the tree trunk or bore to harm back and forth in the phloem, bast, result in the transport of humidity and the nourishment material interruption, cause the whole stub brood tree death finally.Currently, the domestic and international research on Aphrodisium faldermannii rufiventris Gressitt was reported by Jiang Shu-nan (1985).The host plants the larvae period appearance, biology,ecology characteristic and the integrated control method of the insect have not been reported.Research on the space structure,form of characteristics, instar larvae ,biology characteristic demulcent, reconciliation of the insect, control it working to provide science for the prevention and cure synchronously adopt the different prevention and cure measure, sieve the prevention and cure method of the reasonable availability, carrying on the integrated control to the pest;Combine the first step studied the bark feature and total sugar, the dissolubility sugar contents with its the relation for endanger. l.Biology of Aphrodisium faldermannii rufiventris GressittAphrodisium faldermannii rufiventris Gressitt has one generation per 2 years and overwinters in larvaes of the first year and adults of the second year in the bored channel of trunk or branches in various regions of Daiyunshan Mountain,in Fujian Province. The egg presents the long circular, the long path of it is about 4.80 mm. The imago begins to oviposit in the first and the middle of ten days of May, prosperous expect to be for the from the end of May to the beginning of June, the middle ten days of June is to produce the last phase of egg. The egg expects the 7-12 d, the most long can amount to the 17d.The larvae is 8 generations, the period is about 481d.Long 32-36 mm of the male pupa, long 41-52 mm of the female pupa.The antennae, wings, foot does not stick to attach the body of the pupa, the stomach economy energy activity.Can immediately mate after eclosion, mate for the overlap type, thefemale at under the male insect at up, mating hour the female quiet motionless or make the slowness to crawl along, meet surprised the hour then avoids quickly and separately.The copulation can keep on 5-10 min, can amount to the 30 mins, can carry on two times after being separated the 8 min. The adult can copulate many times . Mate 11-17:00 more multifarious, the little nighttime mate. A female adults produce biggest 69 eggs , minimal is 20, produce 4-46 eggs on one stub tree .The female and male compare about 1:1. 2.The space structure and perpendicularities of Aphrodisium faldermannii ruflventris GressittThe regression models test show that M*=a+px , a=0.2881>0, (3=1.3868>1; M'=a'+p/x+y/xV=2.2323>0, p'=1.9947>l;C'=0.034 6x+2.936 8,L/=1.0346S2+2.927 7.That show the space distribution coincides with aggregation distribution. The correlation coefficients of four model are very high.It shows that the four regression model are validate.lt shows that the space distribution coincides with aggregation distribution from different point of view.lt is calculated that p'>p\, Po |
