稻暝啮小蜂是三化螟的一种寄生蜂,1957年于温州市郊的第三代三化螟卵块里初次发现,卵寄生率仅0.2%,1962年第四代三化螟卵寄生率上升到1.7%,1963年第三、四代三化螺卵寄生率迅速上升分别达3.1%和39.2%,我所当时曾对此蜂作了一些调查研究,1964年以后田间螟卵寄生率骤然降低,1971年重新采集三化螟各代卵块885块,经检查未见有该蜂寄生。现将1962-1963年饲养调查结果整理如下,供今后探讨啮小蜂在本地利用和保护的参考。
Ophiopogon japonicus is a parasitic wasp to the rice stem borer. It was first discovered in the third generation of three stem borer eggs in the suburbs of Wenzhou in 1957, with an egg parasitism rate of only 0.2%. In 1962, the fourth-generation rice borer egg parasitism rate Rose to 1.7%. In 1963, the parasitic rates of the third and fourth triads of Spirulina rapidly rose to 3.1% and 39.2% respectively. Some studies were conducted on this bee at that time. After 1964, Lower, in 1971 to re-collection of three generations of borer 885 eggs, no inspection of the bee parasites. The results of the 1962-1963 rearing survey are summarized below for future reference on the use and conservation of the bees in the country.
