Gain control in olfactory receptor neurons and the detection of temporal fluctuations in odor concentration

open access: yesFrontiers in Physiology, 2023
The ability of the cockroach to locate an odor source in still air suggests that the temporal dynamic of odor concentration in the slowly expanding stationary plume alone is used to infer odor source distance and location.

The mitochondrial genome of Aenasius arizonensis (Hymenoptera: Encyrtidae) with novel gene order

open access: yesMitochondrial DNA. Part B. Resources, 2019
Aenasius arizonensis is the endoparasitoid of mealybug (Phenacoccus solenopsis) and plays an important role in biological control. We sequenced the A. arizonensis mitochondrial genome using next-generation sequencing.

Survive a Warming Climate: Insect Responses to Extreme High Temperatures.

open access: yesAnnual Review of Entomology, 2020
Global change includes a substantial increase in the frequency and intensity of extreme high temperatures (EHTs), which influence insects at almost all levels. The number of studies showing the ecological importance of EHTs has risen in recent years, but

Composition of Anopheles mosquitoes, their blood-meal hosts, and Plasmodium falciparum infection rates in three islands with disparate bed net coverage in Lake Victoria, Kenya

open access: yesMalaria Journal, 2017
Background Small islands serve as potential malaria reservoirs through which new infections might come to the mainland and may be important targets in malaria elimination efforts. This study investigated malaria vector species diversity, blood-meal hosts,
