Current interest in control by release of transgenic males begs attention to this bias. It is well known that males are more susceptible to insecticides than females when determined by the standard World Health Organization (WHO) bioassay, and field observations have shown a higher impact of ultra-low-volume (ULV) space sprays. It is generally assumed that these differences are due to the smaller size of males and/or greater physiological susceptibility. We compared susceptibility by WHO bioassay and by topical application. There was a significant difference between the sexes in terms of dose effect and knockdown by the WHO test, but no significant difference by weight-adjusted topical application. We conclude that greater susceptibility of males is solely a function of their size and suggest that a ULV treatment before the release of transgenic males would greatly increase their competitive ratio versus wild mosquitoes and thus their impact as a control measure. specialized Aedes albopictus insecticide susceptibility male size mosquito control sterile insect technique 052 32 3 251-253 2016 8756-971X https://www.documentation.ird.fr/hor/fdi:010068346 8756-971X [F B010068346] https://www.documentation.ird.fr/hor/fdi:010068346 https://www.documentation.ird.fr/intranet/publi/2016/12/010068346.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2017-01-09 2017-08-23 fdi:010068346 fre
