摘要
东亚小花蝽产卵于植物组织内,为了寻找大量繁殖小花蝽时适用的优良产卵植物,在实验室采用3种植物供其选择产卵,结果小花蝽在黄豆芽、连翘嫩梢和菜豆荚上产的卵,分别占59.1～67.4％,23～32.9％和7.7～9.5％。在500毫升容器中饲养小花蝽,其产卵量随黄豆芽的增加而递增,当每头雌虫给予约一根黄豆芽供作产卵时,一生产卵51.9粒。产有小花蝽卵的黄豆芽在0～4℃冰箱中冷藏3～8天,孵化率均在90％以上。用黄豆芽作产卵植物繁殖小花蝽,成虫获得率可达50.1～84.4％。由于黄豆芽可在室内终年供应,手续简单,作为小花蝽产卵植物着卵多,孵化率高,耐冷藏,适用于室内大量繁殖。
In the laboratory studies conducted in Beijing during 1987-1990, soybean (Glycine max) sprouts, young shoots of Forsythia suspensa and pods of Phaseolus vulgaris were compared for their suitability to be used as oviposition material in mass rearing Orius sauteri. In a multiple choice test, proportions of eggs laid on the three materials were 59.1-67.4%, 23-32.9% and 7,7-9.5%, respectively. When the rearing density in 500 ml containers was about 1 predator:1 bean sprout, an average of 51.9 eggs were collected in the life span of a female. The bean sprouts carrying the eggs could be stored under 0-4癈 for 8 days with over 90% hatching rate. The percentage of obtaining adults from . rearings with this method was 50.1-84.8%.
