A Study on Setting Equipment of Manufactured Reproduction of Trichogramma

It has been proved in practice that artificial reproduction of trichogramma is a safe,effective and economic method in control of corn borer. In present study, the popular method of trichogramma reprodution in China,in which tussah silk-worm ovum is used as host,was improved. The whole procedure of the trichogramma production was divided into ovum collecting and cleaning, immature ovum eliminating,dehydrating,mixing,ovum sepreading,ovipositing,non-host ovum separating and packing. Based on the procedure,a series of equipments were desgined,which make the eliminating of immature ova,separating of non-host ova more efficiently,and make the climate condition artificially controlled. An automatic product line,with the capacity of 40 billion heads of trichogramma annually,was established.
