摘要:

研究球孢白僵菌侵入后桑天牛幼虫血细胞的防御反应。结果表明: 对照桑天牛幼虫血细胞种类和数量基本稳定,而接种白僵菌分生孢子对桑天牛幼虫血细胞数量有显著影响。接种第1天,感染昆虫血细胞总数与对照差异不大;1天后,血细胞总数逐渐上升,显著高于对照; 至2.5天达到最高值。接种2.5天后处理虫体内的血细胞总数开始下降,并逐渐降至较低水平。被感染虫体血淋巴中的浆血细胞和粒血细胞表现出类似规律。

Abstract:

The defense response of hemolymph in the larvae of Apriona germari to Beauveria bassianawere studied. The result showed that the kind and number of hemocytes in control Apriona germari larvae were stable, while Beauveria bassiana conidia had significant impact on the number of the hemocytes in Apriona germari larvae. The total number of hemocytes did not change significantly within the 1stday after inoculation. It increased gradually after one day, and reached to maximum in two and half days after inoculation. Then it decreased gradually to the lowest level. The counts of Plasmatocyte and Granulocyte of the hemocytes in the infected Apriona germari larvae showed similar pattern.

Key words: Apriona germari, Beauviera bassiana, hemocyte, defense reaction
