采用喷雾气压恒定为１９６．１３３ ｋＰａ、时间自动控制为３ ｓ的ＺＨＬ９７型喷雾器对荔枝蝽卵平腹小蜂喷雾甲胺磷．结果表明，在２２～３０ ℃、（７０±５）％ ＲＨ、１４ Ｌｖ１０ Ｄ光照条件下，甲胺磷对荔枝蝽卵平腹小蜂的毒性随温度的升高而增大， ＬＣ５０为甲胺磷田间推荐使用浓度稀释倍数（１ｖ１ ０００）的２２～４８倍（即１ｖ２２ ０００～１ｖ４８ ０００）．
Using spray constant pressure of 196.133 kPa, automatic control of the time 3 s ZHL97-type sprayer on the litchi stool wasp spray methamidophos. The results showed that the toxicity of methamidophos to Lygus ludwig was increased with the increase of temperature under the conditions of 22 ~ 30 ℃, (70 ± 5)% RH and 14 L × 10 D illumination, and the LC50 was methylamine Phosphorus field recommended concentration dilution (1v1000) 22 ~ 48 times (ie 1v22000 ~ 1v48000).
