冀东地区南美斑潜蝇的发生及其防治

Occurrence and Control on Liyiomyza huidobrensis In Jidong

为明确冀东地区南美斑潜蝇的发生规律及其最佳防治方法,采取分区设点的方式调查其发生规律,结果表明：南美斑潜蝇在冀东地区温室发生10-13代,露地一年发生5-6代,不同的温湿度南美斑潜蝇的发育历期不同,表现为随着温度的升高发育历期缩短,发育的最适温度为25℃,最适湿度为70%,防治其最适的药剂组合为2.0%阿维、50%潜克、5%尼索朗1：29：5混配3000倍液防治效果最好,最适时期为卵期,防治效果达到95.83%,减退率达到96.43%,处理之间差异显著。

Regulartions of occurrence and method of control to Liyiomyza huidobrensis was investigated in different partition of JiDong. The result showed that Liriomyza Huidobrensis occured 10-13 in greenhouse and 5-6 generations in bare land each year, time of each generation changed with temperature and humidity, the optimum temperature and humidity was 25℃ and 70%, the optimum medicament was mixtures of 2.0% Abamectin. 50%dichlorvos, 5%Cyromazine and Nissorm in proportion as 1：29：5, Liyiomyza huidobrensis cound be controled effectively in egg period which the corrected mortalities and decrement were 95.83% and 96.43%, mixed medicament was significantly different from Cyromazine.
