为了解2%阿维·绿僵菌素悬浮剂对朱砂叶螨的生物活性,采用盆栽幼苗喷雾法、盆栽幼苗喷雾法、保湿叶碟喷雾法研究了2%阿维·绿僵菌素悬浮剂对不同生长阶段朱砂叶螨的生物活性,并采用茎内吸法、涂药法研究了2%阿维·绿僵菌素悬浮剂的内吸性和渗透性,探讨了温度对其杀螨活性的影响。结果表明:2%阿维·绿僵菌素悬浮剂对成螨的活性(LC50:1.247 44 mg/L)优于唑螨酯(LC50:2.189 50 mg/L)和炔螨特(LC50:12.515 49mg/L),对若螨的活性(LC50:0.362 31 mg/L)低于阿维菌素(LC50:0.279 71 mg/L),其杀卵活性(EC50:3.563 50mg/L)优于哒螨灵(LC50:5.561 61 mg/L)但低于噻螨酮(LC50:0.274 23 mg/L);2%阿维·绿僵菌素悬浮剂对不同生长阶段的朱砂叶螨均具有较高的活性,其内吸性、渗透性均较强,在一定的温度范围内,温度越高,杀螨活性越高。本研究结果为2%阿维·绿僵菌素悬浮剂的田间应用提供了理论依据。
In order to understand the biological activity of 2% Avicenchus SC against SCs, we studied the effects of 2% Aviagen Suspension Suspension on potted seedlings, The biological activity of Tetranychus cinnabarinus in different growth stages was studied. The internal absorption and permeability of 2% Avaricin Suspension were studied by stem suction method and coating method. The effects of temperature on its acaricidal activity Impact. The results showed that the activity of 2% AVS was better than that of acarbamycin (LC50: 2.189 50 mg / L) and propargite (LC50: 12.515 (LC50: 0.362 31 mg / L) was lower than that of abamectin (LC50: 0.279 71 mg / L), and its ovicidal activity (EC50: 3.563 50 mg / L) Mites (LC50: 5.561 61 mg / L) but lower than that of hesperidin (LC50: 0.274 23 mg / L); and 2% SA of SCs had higher levels of Tetranychus cinnabarinus in different growth stages Activity, its internal absorption, permeability are strong, in a certain temperature range, the higher the temperature, the higher the acaricidal activity. The results of this study provide a theoretical basis for the field application of 2% Avastin suspension.
