Preliminary Study On The Ultrastructure Of Camptoloma Interiorata Tentacles And Natural Enemies

Camptoloma interiorata(Walker)is an important leaf pests,has seriously affected our country forest health.This study use type of Camptoloma interiorata antennal sensilla were observed by scanning electron microscope,the number and distribution,and through field investigation and indoor artificial feeding on its natural enemies.The main results are as follows:1.Camptoloma interiorata types of female and male antennae of sensors on the same,have 8 kinds of sensors,including: sensillum squamiformium,trichoid sensilla,sensilla chaetica,sensilla basiconica,sensilla auricillica,styloconic sensillum,sensilla coeloconica and B?hm bristles,but various types the sensor is the differences in the number and distribution of sensilla,which I is only distributed in the antennal surface camptoloma interiorata adult male.Camptoloma interiorata antennae with sensor type in other lepidopteran insects also have distribution,its shape and structure and other lepidopteran insects are similar,only different in the part of the distribution and quantity.2.In 2016,through investigation in Dalian of Jinzhou,Jinhu mountain and found 1 enemies the parasitic rate was 2.31%,2 natural parasitism rate is 0.11%.2017 in April,once again conducted a survey of camptoloma interiorata predatory and parasitic natural enemies in the area.The findings are as follows: predator Paratenodera aridifoliaThe average population density is 0.28 + 1.01(head / plant);three parasitoid species,density of insect predators 1 is 1.3 + 0.34(head / bud)were 2,the population density of 0.32 + 0.12(head / shell),density of insect predators 3 is 0.169 + 0.16(head / bracts);1 natural enemies cocoon was ellipsoid,yellowish brown tomentose,covering the surface of natural enemies.2 white cocoon ellipsoid,slightly larger than the volume of natural enemies 1.natural enemies and 3 light yellow cocoon cocoon ellipsoid.By comparison analysis(LSD)were 1 and 2 of natural enemies,3 natural enemies have significant differences.3.The use of Arma chinensis on predation function of predatory function of Camptoloma interiorata reaction experiment results,research shows that the camptoloma interiorata 3,4 instar larvae of Arma chinensis with Holling?functional response type,density in the range of the experimental design,with the increase of the density of Camptoloma interiorata larvae of Arma chinensis predation rate gradually increased,when the cloth the moth density increased to a certain extent,the predation amount of Arma chinensis increased slowly.The predation of Arma chinensis on Camptoloma interiorata 4 instar state is far greater than that of Camptoloma interiorata 3 instar state predation ability.
