摘要:

通过观察黑翅土白蚁的觅食行为,对黑翅土白蚁的食物选择性作了研究。室内结果表明:在6种纯饵料中,小米粉的被食率、泥被面积及泥被覆盖率均最高,其泥被出现时间仅长于松木粉,但两者间无显著差异。在5种添加物中,除15%黑木耳外,15%香菇、10%松花粉、10%白砂糖、15%蜂蜜都能显著提高小米粉对黑翅土白蚁的诱食效果,其中又以10%白砂糖的增效作用最为明显。野外试验结果表明,小米粉+10%白砂糖诱饵对黑翅土白蚁的诱食效果优于小米粉诱饵。可见,小米粉+10%白砂糖是最优化的饵料组合,可作为黑翅土白蚁毒饵中的饵料组分。

Abstract:

By the observation for the foraging behavior of Odontotermes formosanus, the food choice of this termite was studied.The results showed that in the six diets, the consumption rate, mud sheet area and mud sheet covering rate of the millet powder were maximal. The mud sheet appearing time of the millet powder was only longer than that of the pine powder, but difference between the two diets was not significant. Among the five additives, except for 15% Auricularia auricula, 15% Lentinula edodes, 10% masson pine pollen, 10% powdered sugar and 15% honey could observably improve the phagostimulating effect of the millet powder on O. formosanus, and the synergistic effect of 10% powdered sugar was the most distinct in them. The results of the field trial showed that the phagostimulating effect of the baits made of the millet powder+10% powdered sugar on O. formosanus was better than that of the baits made of the millet powder. To sum up, the millet powder+10% white sugar was the best diet component, and it can be the diet ingredient of the poison bait against O. formosanus .
