中文摘要: |
用喷雾法对荔枝蛀蒂虫卵进行13 种杀虫剂的杀伤效果试验。结果表明:参试杀虫剂在稀释2 000
倍时,2.5% 高效氯氟氰菊酯EC、480g/L 毒死蜱EC、10% 联苯菊酯EC、10% 醚菊酯SC、10% 虫螨腈SC、60
g/L 乙基多杀菌素SC、35% 硫丹EC、20% 甲氰菊酯EC 等8 种农药对虫卵的杀伤率可达50% 以上;在稀释1
000 倍时,只有10% 联苯菊酯EC 杀伤率可达100%、2.5% 高效氯氟氰菊酯EC 杀伤率有93%,1.8% 阿维菌素
EC-480 g/L 毒死蜱EC(1∶1)、35% 硫丹EC、480 g/L 毒死蜱EC、10% 醚菊酯SC、1.8% 阿维菌素EC-20% 甲
氰菊酯EC(1∶1)、10% 虫螨腈SC 等6 种农药的杀伤率为70%~80%,而20% 甲氰菊酯EC 与60g/L 乙基多杀
菌素SC 2 种农药的杀伤率仅为60% 左右,1.8% 阿维菌素EC、5% 多杀霉素SC 与4.5% 高效氯氰菊酯EC 3 种
农药的杀伤率在50% 左右,240 g/L 氰氟虫腙SC 及20% 氯虫苯甲酰胺SC 2 种农药的杀伤率只有40%。可见
在现有杀虫剂中,大多数品种对荔枝蛀蒂虫卵只有一定效果,能完全杀伤荔枝蛀蒂虫卵的品种不多。 |
英文摘要: |
The litchi Conopomorpha sinensis may be more effectively controlled by killing their eggs. In the
present study,the control effect of 13 insecticides were detected by applying to the eggs of the insect. The results
showed that,3d after spray with 1000 times dilution,only one product,10% bifenthrin EC,had a 100% killing
rate,followed by 2.5% lambda-cyhalothrin EC with 93% killing rate. Six insecticides,1.8% abamectin EC - 480g/
L chlorpyrifos EC(1∶1),35% endosulfan EC,480 g/L chlorpyrifos EC,10% etofenprox SC,1.8%abamectin
EC-20% fenpropathrin EC(1∶1),10% chlorfenapyr SC,got a killing rate between 70~80%. 20% fenpropathrin
EC and 60g/L spinetoram SC killed about 60% of the eggs.Three products,1.8% abamectin EC,5% spinosad SC and
4.5% beta-cypermethrin EC killed 50% of the eggs;20% 240g/L metaflumizone SC and chlorantraniliprole SC got a
very low controlled effect,with only 40% killing rate. It can be seen that Relatively few existing insecticides can be
used to control the C. sinensis eggs. |
