The paper deals with the practical program to evaluate the mixture insecticide in BASIC language,the calculate formula of cotoxicity coefficient is modofied and consummated.Based on the most important quota,LC90,the general formula is as follows:CTC=100/LC90 about the mixture/A,where A means the sum of the ratio between the content and LC90 of the single.This program simplifies the calculate steps,raise the calculating efficiency and the precision.

应用BASIC语言编制了评价复混药剂的实用程序,并对共毒系数的计算公式加以修改与完善。以LC90值作为更重要的评价依据,采用共毒系数简化泛式:CTC=100/混剂LC90/∑(混剂中单剂含量/单剂的LC90,精简了运算步骤,提高了运算速度和试验精度。

The paper desericbed the results of study on toxicity of Chinese Herbal medicine liquid mixture insecticide Y-13 and Y-17 for Xenosylla cheopis.

本文报道了两种中草药混配杀虫液剂代号为Y-13、Y-17它们对印鼠客蚤(Xenopsyua cheopis)的毒力测定结果。用瓶膜接触法,Y-13的药膜剂量为0.2983ul/cm~2(含原药液量),对雌、雄蚤的KT_(50)分别为2.0833min、1.6825min。瓶膜残效可达1月,水磨石砖面和瓷砖面残效均为15天,玻璃面残效时间达120天。Y-17的膜剂量为0.4053ul/cm~2(含原药液量),对雌雄蚤的KT_(50)均为2.9635min,瓶膜残效可达半月,水磨石砖面残效小于15天,玻璃面、瓷砖面残效均为15天。两种药剂对该蚤10min内的击倒率及24h死亡率均为100%。结果表明,两种液剂对蚤具有速杀、高效的毒杀作用,且Y-13的残效时间比Y-17长,两种药物药源丰富,具有一定研究及开发的前景。

So far all single chemical insecticides and most of mixture insecticides were presented by cotton bollworm(Helicoverpa armigera)(CBW)in north cotton areas of china.It's an effectively method to control resistance CBW with hereditary control tactics, for example,sterilant.It's not only significantly decreasing density of field pest porplulation but also is supplement for TPM.During 1983~1997,carried out the gossypol that have been used prophylactic in 1970's in laboratory and field.The results indicated that sterility effect was rather good using gossypol to control CBW.Before CBW mating we Feed adult with over 800 ppm gossypol in laboratory,the efficacy was 100%.From 1995 to 1997,we applied mixture included 3000 ppm gossypol ,male sex allure and attractant to control 2nd,3rd,4th generation CBW AT 333.3~1000ha cotton acreage.The results showed that gossypols were applied from 2.25 to 6.75g per ha could decrease eggs 52.6%~72.8%,mean 63.3%;decrease larbae 34.2%~60.8%,mean 45.7% and increase 7.8%~15.0%,mean 10.9% cotton yield as well as reduce 7 times chemical pesticide control per year.It is first reported to use directly sterilant and need not artificial rear,fly sterility male insect to control field pest in the world.

在棉铃虫几乎对所有商品化学农药单剂产生高抗性的今天,应用遗传防治法,如不育剂,既能有效地降低害虫田间种群密度,又是对TPM的补充,经过1983~1997年室内外试验表明,曾在70年代用于人类男性的避孕药剂———棉酚,能有效地造成棉铃虫雄性不育。我们不必在室内饲养大量的不育虫,直接将不育剂用于田间,取得理想的防治效果。室内试验表明,在棉铃虫交配前,用浓度大于800mg/kg的棉酚液饲喂雄性棉铃虫,能达到100%的不育效果。1995~1997年连续三年对棉田一、二、三代棉铃虫3333至1000hm2示范表明,将3000mg/kg的棉酚与性诱剂、诱食剂结合,全年每hm2应用棉酚225~675g,即可造成百株卵量减少526%~728%,平均633%;百株幼虫数减少342%~608%,平均457%;每年减少化防次数7次;皮棉产量增加78%~150%,平均109%,将不育剂在田间直接应用,而无需人工饲养、放飞不育虫的方法,世界上还未见报导。
