准确地进行紫胶虫的涌散测报,适时采种,科学放养,精心管理,是决定放养工作成败的关键性技术措施。测报的方法很多,要根据具体情况,互相补充,互相配合,综合应用。一、用世代发生日期来推算我们西昌地区紫胶虫一年发生两代:夏代5—10月,下一代幼虫大多在10月涌散;冬代10—次年5月,幼虫大多在5月涌散。夏代历时4个月,约120天,冬代历时7个月,210天。从放养的次日起算,接近世代交
It is a key technical measure to determine the success or failure of the stocking operation by accurately measuring the larvae of the lac bug, timely collecting the seed, scientific stocking and careful management. There are many ways to measure the report, according to the specific circumstances, complement each other, cooperate with each other, and comprehensively apply. First, using the date of generation to infer that we have two generations of lacongoons in Xichang: from May to October in the Xia Dynasty, most of the next generation of larvae are scattered in October; in the 10th and the following May of the winter, the larvae mostly live in May Influx. Summer lasted 4 months, about 120 days, winter lasts 7 months, 210 days. From the stocking the next day count, close to the generation to pay
