采用诱饵诱集法研究了荒地、绿化带生境中红火蚁蚁丘体积、蚁丘表面基部面积与诱集工蚁数量之间的关系.结果表明：在荒地生境中，随着蚁丘体积的增大，诱集工蚁数量表现为先迅速增加、后增大减缓、最终趋于平衡的规律，当蚁丘体积、蚁丘表面基部面积分别为11634 cm3、1308 cm2时，诱集工蚁数达到最大值，为每诱饵291 头；在绿化带生境中，随着蚁丘体积的增大，诱集工蚁数量动态与荒地生境相似，当蚁丘体积>18089 cm3时，诱集工蚁数量的增幅明显变缓，当蚁丘体积为25974 cm3时，诱集工蚁数达到最大值，为每诱饵232头.韦布尔函数方程可较好地描述诱集的红火蚁工蚁数量与蚁丘体积、蚁丘表面基部面积间的关系.
By the method of bait trapping, this paper studied the relationships b
etween mound size (mound volume and mound surface base area) and captured ergate
amount of Solenopsis invicta in wasteland and greenbelt. In wasteland, with
the
increase of mound size, the amount of captured S. invicta ergates increased
rap
idly at first, slowed down then, and kept stable at last. When the mound volume
and surface base area were 11634 cm3 and 1308 cm2 respectively, the captured
ergate amount reached the maximum, being 291 individuals per trap. Similar patt
erns were observed in greenbelt. The increase of captured S. invicta ergate
amou
nt slowed down rapidly when the mound volume was larger than 18089 cm3, and re
ached
the maximum (232 individual per trap) when the mound volume was 25974 cm3. The
We
ibull equation could better describe the relationships between the mound volume
and mound surface base area and the captured ergate amount of S. invicta.
