调查结果表明,桔全爪螨在温州蜜桔上的数量消长动态与温度、叶龄和降雨有关。3月到4月上旬,由于气温在20℃以下,螨量保持越冬水平。随着温度升高,虫口逐渐上升,5月中旬出现第一个高峰。6月初在春稍上出现第二个高峰。6月下旬到7月上旬和8月下旬到9月,由于降雨增多,螨量大大下降。因此,药剂防治时间以5月中、下旬为宜。 The results showed that the dynamics of the growth and decline of the quantity, the temperature, the leaf age and the rainfall of the orange holm mite in Wenzhou tangerine were related. March to early April, as the temperature below 20 ℃, mite amount to maintain winter level. As the temperature rises, the population gradually increases and the first peak appears in mid-May. The second peak appeared on the spring in early June. In late June to early July and late August to September, the amount of mites dropped significantly due to increased rainfall. Therefore, the agent control time in mid-May, late is appropriate.
