Abstract

Abstract: Semanotus bifasciatus is one of the severe wood-borers on cypress trees,Sclerodermus guani is a good natural enemy of stem borers and plays an important role in natural controlling the damage of longhorned beetles.In this paper,indoor parasitism test and field experiment were carried out to determine the potential of using S.guani to control S.bifasciatus.Different host-parasitoid ratios had no significant influence on the developmental duration of S.guani.After parasitizing the larvae of S.motschulsky,the S.guani developed for one generation about 35-36 days.5-7 days after inoculation,the parasitoid began to lay eggs on the surface of S.bifasciatus larvae.5-6 days later,the eggs hatched.2-3 days later,it pupated.19-22 days later,it emerged.The number of females in offsprings was significantly higher than that of males.When the host-parasitoid ratios were 1:1,1:2 and 1:3,the hatching rates were 94.75%,90.68% and 63.34% respectively;the eclosion rates were 87.97%,80.39% and 29.18% respectively.With the increase of S.guani population,the number of eggs laid (79.17) and hatching (49.83) increased gradually,reaching the maximum at 1:3.The variation trend of eclosion was basically opposite to that of oviposition and hatching,that is,with the increase of S.guani population,the number of eclosion (14.33) gradually decreased,reaching the lowest at 1:3;When the host-parasitoid ratios were 1:2,1:3 and 1:4 in vitro branch parasitic experiment,the parasitism rates were 19.57%,37.95% and 16.37%,respectively.In the field experiment,S.guani climbed out of the glass tube to search for the host 2-3 seconds after inoculation.After 2-3 days,S.guani found and began to dig the boreholes of the larvae of S.bifasciatus.20 days later,S.guani successfully parasitized the larvae of S.motschulsky and pupated.30 days later,the offspring of S.guani emerged into adults and drilled out the boreholes to find the host again.When the host-parasitoid ratio was 1:3,the parasitism rate was 18.18%-54.55% and the average parasitism rate was 27.30%.
