平腹小蜂是荔枝蝽卵的寄生蜂,我们发现蓖麻蚕卵是这种寄生蜂室内繁殖的优良寄主。平腹小蜂在繁殖利用上有下列优点:(1)世代历期不长,便于大量繁殖。在30℃温度条件下,胚胎及胚后发育的十五天;(2)成虫寿命长,常温下,雌蜂寿命约一个月;雄蜂约七、八天。雌蜂寿命丧,产卵期也长,在田间发生作用的时间也长;(3)雌蜂羽化交尾以后,不必重复交尾,即可继续产受精卵;(4)在广州地区平腹小蜂可以以幼虫过冬,翌春羽化,根据这个特性,可在晚秋大量繁殖,来春应用。蓖麻蚕卵冷藏于0—5℃温度下经60天,仍可供繁殖之用。平腹小蜂的老熟幼虫冷藏于0—5℃温度下,经112天,仍有95%可化为成虫。这些现象,都有利于大量繁殖及蜂量的累积。1961年春季放蜂治蝽试验的结果:每株5—8公尺高的荔技树,放雌蜂约一百头,十天后,荔蝽卵寄生率提高到89.5%;而对照区的寄生率只有32.9%。初步认为平腹小蜂可用于生产实践。
Baphicola is the parasitic wasp of Lygus stinkbug eggs, and we found that the castor-silkworm eggs are excellent hosts for the intra-plantal reproduction of this parasitic wasp. Baphicorp bee on reproduction has the following advantages: (1) generation period is not long, easy to multiply. In 30 ℃ temperature conditions, the development of embryos and embryos fifteen days; (2) adults long life, at room temperature, the female life of about one month; drone about seven or eight days. Female bees longevity, spawning period is also long, the role of the time in the field is also long; (3) females emergence after mating, do not have to repeat the mating, you can continue to produce fertilized eggs; (4) in Guangzhou, Larvae can be winter, the next spring eclosion, according to this feature, a large number of breeding in late autumn, spring application. Castor silkworm eggs frozen at 0-5 ℃ temperature by 60 days, is still available for breeding purposes. The mature larvae of Aplysia Beringiana are refrigerated at temperatures between 0 and 5 ° C. After 112 days, 95% of adults are still adults. These phenomena are conducive to a large number of breeding and bee accumulation. In the spring of 1961, the result of the experiment on beetle poisoning showed that the number of female bees was about 100, and the parasitism rate of litchi stool increased to 89.5% after 10 days. The parasitism of the control area Only 32.9% rate. Preliminary thought that Baphicola bee can be used for production practice.
