摘要

將1.65% hydramethylnon毒餌置於蜚蠊出沒處，可誘引蜚蠊取食，取食者於數日內死亡，同群其牠未食餌者亦可逐漸死亡，證實取食毒餌中毒之蜚蠊可傳播毒劑予其牠個體進而使之致死，毒劑傳播之方式乃經由蜚蠊的食糞行為形成，證明hydrame-thylnon毒餌之二次毒性效應。另以1.65% hydramethylnon大毒餌(上表面56cm^2)在台北南港中研究附近20坪大的住家進行實際應用測試，1993年9-12月使用6個毒餌，蜚蠊之減少率為68-70%，1994年4-6月使用12個毒餌，減少率降為37-64%，1994年7-10月使用6個毒餌減少率為0-39%；使用12個毒餌減少率為27-52%。可知，在20坪的進戶如單獨使用此毒餌防治蜚蠊，秋冬季每戶放6個毒餌即可，春夏季則每一戶至少要放12個毒餌，方可達到效果。於試驗住戶誘捕蜚蠊之結果美洲蜚蠊Periplaneta americana (L.)佔58.1%為最高、澳洲蜚蠊P. australasiae (Fab.)32.4%次之。捕獲的地點則以富含食物的廚房為主。

Bait with 1.65% hydramethylnon was tested for the control of cockroaches. The roaches were attracted to the bait and fed on it. The poisoned roaches died within several days and furthermore, the cockroaches in the colony which did not feed directly on the bait were also died. Results ovtained in this study indicate that cockroaches feeding on toxic bait can transfer lethal toxic sub-stances to other roaches in the colony. Six 1.65% hydramethylnon bait trays (56cm^2) were tested in houses (66m^2) at Nankang, Taipei, for three months months from September to December 1993. The reduction rates of cockroaches in these houses were 68-70%. Subsequent tests were carried out again from April to June and from July to October 1994. The effects of six bait trays were the same with the control groups, yet 37-65% reduction rates were found using the twelve trays in a house in the period April to June, and 27-52% reduction rates from July to October. These results reveal that six hydramethylnon baits were sufficient in reducing the roach population in house of 66m^2 during autumn and winter. However, more than 12 baits were required to control roaches during spring and summer. The cumulative capture percentages of Periplaneta americana, P. australasiae, P. brunnea, Blattella germanica and Pycnoscelus surinamensis were 58.1%, 32.4%, 8.7%, 0.5% and 0.2%, respectively. The kitchen was the area where most roaches were caught.
