Aedes Sierrensis

Abstract The western tree hole mosquito, Aedes sierrensis (Ludlow), is a common nuisance mosquito and vector of Dirofilaria immitis (Leidy), the etiologic agent of dog heartworm, in western North America. Here, we compare weekly mosquito collections made with Mosquito Magnet (MM) traps, Biogents Sentinel (BGS) traps, and Biogents Bowl (BGS Bowl) traps set in Salt Lake City, UT, from the start of June to mid-August 2017. We found the number of mosquitoes decreased with rainfall and temperature independently of trap type. The highest number of mosquitoes were caught by BGS traps baited with carbon dioxide (CO2) and BG lure, which collected 62% (n = 422) of all mosquitoes, followed by the MM at 31% (n = 213), and both the BGS and BG Bowl with BG lure had 3.5% (n = 24) each. Aedes sierrensis females were caught weekly at similar densities (mean ± SD) in BGS with CO2 and lure (1.17 ± 2.93) and the MM (1.17 ± 2.66) traps during the study period. Given that BGS with CO2 and lure traps have several operational advantages over MM traps, including a quicker setup, smaller size, and lower cost, we consider BGS with CO2 and lure traps as the best suited surveillance tool to detect and remove Ae. sierrensis in the western United States and similar settings throughout North America.

Copulatory Position

AbstractAedes sierrensis (Ludlow), the western tree-hole mosquito, is the first species of the pulchritarsis-varipalpus group of the subgenus Ochlerotatus which has been shown to have the masculine genotype modified by thermal pressure applied to developing larvae. A rearing temperature of 30.0 °C. during instars 1-3 and the first half of 4, and 31.0° during the last half of instar 4 will modify the degree of masculinity of the palpi, antennae, oral stylets and testes. Modified males are impotent because the genital section fails to rotate to the copulatory position.
