萧山县1961—1964年四年放养金小蜂的经验证明,防治棉仓越冬红铃虫效果平均达92.69％,田间效果在第一代达64.18％,第二代达31.84％。但大量繁殖金小蜂的饲料问题不易解决,我们于1962—1963年进行了大量繁殖金小蜂的红铃虫茧收集方法试验,初步得出以盒装草灰强制红铃虫结茧法最为理想,方法简便,收茧量大,养蜂效果优良。两年来,应用灰茧饲养繁殖金小蜂达721万头,金小蜂的生活力及在棉仓内寄生率与草茧均无差别,为今后解决大量繁殖金小蜂饲料问题找到了一条新的途径。现将初步结果报告如下。
Xiaoshan County 1961-1964 four years of gold beekeepers’ experience shows that cotton bollworm control overwintering effect averaged 92.69%, field effect in the first generation reached 64.18%, the second generation reached 31.84%. However, the problem of feeding large numbers of golden bees is not easy to solve. In 1962-1963, we conducted a large number of test methods for collecting the red cocoon of golden bees, and concluded that box cresking is the best way to force the cocoon of pink bollworm , The method is simple, received a large amount of cocoon, beekeeping effect is excellent. In the past two years, the application of gray cocoon feeding breeding gold bee reached 7.21 million, the viability of gold wasps and in the cotton compartment parasites and grass cocoon no difference for the future to solve the problem of large numbers of breeding gold bee found a new feed Way. The preliminary results are reported below.
