Abstract

The present study was effected aiming the verification of the seasonal, spatial and hourly of the phlebotominic species found in the county of Itupeva. Captures were performed fortnightly and 864 sand flies were collected between april/94 and march/95. 81.3% of the captured specimens belonged to 4 species: L. migonei (32.4%), L. whitmani (26.0%), L. intermedia (12.0%) e L. fischeri (10.9%). Such species showed larger densities during the cold and dry season of the year (from april to september/94) and were more active between the second and the fifth hour after twilight. L. migonei predominated almost in all the investigated surroundings being followed by L. whitmani and L. longipalpis in the domestic environments. In conclusion it is thought that in conjunction with L. intermedia, a suspect vector in the State of São Paulo, L. migonei and L. whitmani may have an important role in the transmission of cutaneous leishmaniasis in the area under study.

摘要

本研究旨在核实伊图佩瓦县发现的白蛉种类的季节、空间和小时分布情况。每两周进行一次捕捉,在1994年4月至1995年3月期间共收集了864只白蛉。81.3%的捕获标本属于4个种类:米氏白蛉(32.4%)、惠特曼白蛉(26.0%)、中间白蛉(12.0%)和费氏白蛉(10.9%)。这些种类在一年中的寒冷干燥季节(1994年4月至9月)密度较大,在黄昏后第二至第五小时更为活跃。米氏白蛉几乎在所有调查环境中占主导地位,在家庭环境中其次是惠特曼白蛉和长须白蛉。总之,人们认为,与圣保罗州疑似传播媒介中间白蛉一起,米氏白蛉和惠特曼白蛉可能在研究区域皮肤利什曼病的传播中起重要作用。
