By FILIBERTO REYES, EDUARDO REBOLLAR, ILDEFONSO FERNANDEZ and J. ANDRADE

Abstract

Sandflies attracted by human bait were caught in an endemic focus of localized cutaneous leishmaniasis in the state of Campeche, Mexico. Catches were carried out monthly from February 1994 to January 1995 between 18:00 and 22:00 h. Lutzomyia cruciata was the only species caught. The highest populations peak of Lu. Cruciata was found in March with lesser peaks in February, December 1994, and January 1995. Maximum biting rate of Lu. Cruciata was found between 18:00 and 19:00 h. The host-seeking females of Lu. Cruciata were directly related to levels of humidity between 88 and 100%. Low and high temperature had a negative effect upon Lu cruciata activity. The possible role of Lu. Cruciata as vector of leishmaniasis in the state of Campeche, Mexico is discussed
