Effects of Zika Virus Strain and Aedes Mosquito Species on Vector Competence

Emerging Infectious Diseases, 2017
In the Western Hemisphere, Zika virus is thought to be transmitted primarily by Aedes aegypti mosquitoes. To determine the extent to which Ae. albopictus mosquitoes from the United States are capable of transmitting Zika virus and the influence of virus ...

Warming‐Mediated Decreases in Nectar Quality Translate Into Lower Energy Reserves of the Monarch Butterfly (Danaus plexippus)

Global Change Biology Communications, EarlyView.
Warming caused a significant decrease in monarch fat mass, likely due to an observed reduction in sucrose concentration caused by warming of the nectar. Since sucrose fuels fall migration and overwintering, our results suggest climate warming may reduce migration success and overwinter survival.

Reduction in Aedes aegypti Population After a Year-Long Application of Targeted Sterile Insect Releases in the West Valley Region of Southern California

Insects
Aedes aegypti is of great public health concern because of its vectorial capacity to transmit various arboviruses such as Zika, yellow fever, dengue, and chikungunya. In California, its expanding geographic distribution has been unrestrained.

Predicting the likelihood and intensity of mosquito infection from sex specific Plasmodium falciparum gametocyte density

eLife, 2018
Understanding the importance of gametocyte density on human-to-mosquito transmission is of immediate relevance to malaria control. Previous work (Churcher et al., 2013) indicated a complex relationship between gametocyte density and mosquito infection ...

A clustered regularly interspaced palindromic repeat‐Cas12a‐based assay for rapid dengue virus monitoring in mosquito and clinical samples facilitating global collaborative surveillance and risk assessment to block dengue spreading

Interdisciplinary Medicine, EarlyView.
The RAA‐Cas12a assay outperforms real‐time PCR in sensitivity (92.3%) while matching its specificity (100%) for dengue virus detection in clinical samples. It effectively identifies DENV in mosquitoes, with field data correlating to local outbreaks. This rapid, simple, and precise method serves as an early warning tool for dengue management.

Mosquito co-infection with Zika and chikungunya virus allows simultaneous transmission without affecting vector competence of Aedes aegypti

PLoS Neglected Tropical Diseases, 2017
Background Zika virus (ZIKV) and chikungunya virus (CHIKV) are highly pathogenic arthropod-borne viruses that are currently a serious health burden in the Americas, and elsewhere in the world.

Wild Animal Suffering Is Not Intractable: A Precautionary Approach to Compassionate Intervention

Journal of Applied Philosophy, EarlyView.
ABSTRACT Wild animals suffer due to human activity, yet natural factors contribute far more significantly to their suffering. In light of this, some propose that we have a pro tanto obligation to intervene in ecosystems to improve wild animal welfare.
