Study on Bionomics of Rice Ephydrid Ephydra macellaria Egger

Zhang Lishen et al (Agronomy Department,Zhelimu Animal Husbandry College Tongliao 028042)  
The rice ephydrid ( Ephydra macellaria Egger) has become one of the most injurious insects of rice in the eastern regions of Inner Monglia since late 1990's.This article was mainly concerned with the bionomics.The results were as the following: There were amphigony and phototaxis of adults and the sex ratio of adults was about 1:1. The entire emergence,copulation and ovipostion of the adults took place in daytime.Of each generation,most of the eggs were laid singly on the surface of float objects on the paddyfield water,74~153 granules per female.The relationship between the longevity of adults females(y) and the quantity of eggs (x) fit the following equation:y=-0.1195x+22.5226,(r=9897  ). The larvae lived in water,biting and snipping rice roots,which induced rice to float out of bed soils and even to death.The experimental results showed that the mean grain yield of rice decreased and the blighted grain rice increased.
