豆天蛾幼虫保藏研究(英文)

In order to solve the seasonal supply problem of Clanis bilineata Walker larvae,effects of larva instar,time and temperature on larvae preservation were studied in this experiment.The results indicated that the 5th instar mature larvae had the best preservation durability,and their optimum preservation condition was 2-4 ℃ with a upper time limit of 8 months.     

豆丹高产养殖技术研究及其效益分析

[目的]探索豆丹的高产养殖技术。[方法]以老熟豆天蛾幼虫为豆丹种,利用大棚培养豆丹种,用网罩及分批种植大豆的方法进行豆丹高产养殖技术研究,并分析其经济效益。[结果]大棚培养有助于豆天蛾的提前化蛹及羽化,首次羽化即第1个成虫飞出的时间比常规方法提早2个多月,而且出现2个羽化高峰。采用网罩及分批种植大豆方法养殖豆丹,可多批次收获青豆丹,豆丹产量是常规方法的4倍多,达3000 kg/hm2以上。利用大棚育种,网罩及分批种植大豆养殖豆丹的粗利润是常规方法的8倍以上,经济效益在290000元/hm2以上。[结论]利用大棚培养豆丹种,用网罩及分批种植大豆方法养殖豆丹,产量是常规方法的4倍多,经济效益可观。
