Fennel is an important medicinal and aromatic plant. Essential oils obtained from this plant have found application in various fields, including the production of botanical insecticides. In two seasons, we evaluated the yields of seeds and above-ground biomass, and we monitored the yield rate,...

Avian malaria, transmitted by Culex quinquefasciatus mosquitoes in the Hawaiian Islands, has been a primary contributor to population range limitations, declines, and extinctions for many endemic Hawaiian honeycreepers. Avian malaria is strongly influenced by climate; therefore, predicted future...

Introduction. Aedes aegypti and Aedes albopictus recognized dengue vectors are considered invasive species that are widely distributed in tropical and temperate regions of the planet. The current distribution of the two Aedes mosquitoes overlap and are affected by interspecific larval competition...

This article presents the National saltmarsh mosquito surveillance programme in New Zealand for the year 2012-2013. Higlights of the surveillance report focused on the species of mosquitoes identified, and sampling of species using statistical algorithm.

Background: This paper examines the individual factors that influence prevalence rates of canine heartworm in the contiguous United States. A data set provided by the Companion Animal Parasite Council, which contains county-by-county results of over nine million heartworm tests conducted during...

Understanding mechanisms fostering coexistence between invasive and resident species is important in predicting ecological, economic, or health impacts of invasive species. The non-native mosquitoes Aedes aegypti and Culex quinquefasciatus have been resident in the southeastern United States for...

Culex pipiens quinquefasciatus were fed blood meals from a live chicken (LC), chicken blood in Alsever's (AC) solution, defibrinated bovine blood (DB), or bovine blood in citrate (CB) and incubated at 28°C. The effects of different blood meal sources were evaluated with respect to rates of blood...

The study was carried out to characterize potential larval habitats in the city of Sekondi with the aim of assessing the relative importance of anthropogenic and natural water bodies as larval habitats. Insecticide-resistance status of Anopheles gambiae senso lato in the southwestern part of the...

Plant extracts have been studied extensively for their insecticidal activity against immature stages and adult mosquitoes. They have also been reported to influence the habitat preference of ovipositing mosquitoes. Ageratum houstonianum, a medicinal plant belonging to the family Asteraceae, has...

Objective: To determine the intrinsic toxicity of hexane, ethyl acetate and methanol crude extracts of Ageratum houstonianum leaves against adult Anopheles stephensi, Aedes aegypti and Culex quinquefasciatus mosquitoes. Methods: Bioassay was performed in 2-day-old laboratory reared unfed adult...
