Over the la.t few deca.es, dengue fever epidem.cs ha.e increa.ed in frequency a.d intensity worldwide, m.king it a.m.jor globa. concern for public hea.th. Its prevention, which is essentia.ly vector-ba.ed control, is a.rea.y being com.rom.sed by reports of resista.ce of the m.in vector a.des a.gypti to insecticides. To ta.kle the ra.id increa.e in insecticide resista.ce a.d outbrea.s, the biologica. vector control is a.prom.sing a.proa.h. One of the stra.egies of this a.proa.h is the use of entom.pa.hogenic fungi beca.se of their grea. effica.y a.d their eco-friendly a.pects. However, som. a.pects of their use, such a. the low efficiency, the high cost of production a.d the sensitivity to va.ious a.verse conditions, need to be a.dressed for their successful la.ge-sca.e a.plica.ion.
