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.

The Impact

Thermal stress is present in metal–organic frameworks undergoing temperature changes during adsorption and desorption. We computed the thermal pressure coefficient as a proxy for this phenomenon and discuss the impact of thermal expansion mismatch.

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.

Thermoelastic Analysis

Considering xz plane heterogeneous mechanical properties and thermal-pressure loads, thermoelastic analysis is applied on orthotropic nose cap of a hypersonic vehicle in the flight trajectory. The results show that the thermal-stress of sphere section presents annular, the Mises equivalent stress is of periodicity of 90° in tail so obviously that a reasonable connection is important. Finally, two connections, bolted and plug connection, are considered to relax the overnice tail constrains, and the results show that the plug connection is reasonable for the hypersonic heterogeneous orthotropic nose cap
