Nemorilla maculosa Meigen is a tachinid parasitoid(Diptera:Tachinidae)of the beet webworm,Loxostege sticticatis Linne(Lepidoptera:Pyralidae)and other lepidopterous insects.It can effectively control the damages of meadow moth,and can regulate population dynamics of insects in the fields.However,the parasitical behavior and bionomics of N. maculosa have been received little attention so far.In this paper,we studied the biology of tachinid fly,selection to host,effects on fecundity of host densities,and effect on tachinid fly's adult reproduce of complement nutrition.The results may provide important scientific gist for biocontrol of meadow moth.1.The biology of N.maculosaThe basic biology of N.maculosa that contained rules of tachinid fly's emergence, oviposition,mating,and developmental period was study.The results indicated that emergence of N.maculosa focus on daily 8:00～10:00 and 14:00～16:00 times.Emergence durative period were seven days.The male eclosion was earlier to female.New emergence female could immediately mate with male.Mating rate was 90%over when provided for male had emerged one day while female mergence.Generally,durative time of mating was about twenty minutes to thirty minutes.The tachinid fly's individual fecundity varied considerably,it was 134.43 on average individual.Durative period of oviposition was 15.47 days,and lay eggs focused on the 3rdto 9thday,it was 67.07%over total.Besides the tachinid fly is single parasitoid in meadow moth.
