Asymmetrical Competition between Aedes aegypti and Culex quinquefasciatus (Diptera: Culicidae) Coexisting in Breeding Sites

Asymmetrical Competition between Aedes aegypti and Culex quinquefasciatus (Diptera: Culicidae) Coexisting in Breeding Sites

Aedes aegypti and Culex quinquefasciatus are mosquito vectors for several tropical diseases that represent a current public health problem. The ecological requirements for each species are different, however, both species show high biological adaptability, which promotes their coexistence in the same breeding sites. The purpose of this study was to assess the effect of larval association betwee...

Efficacy and Sublethal Effects of Mosquito Mats on Aedes Aegypti and Culex Quinquefasciatus (diptera: Culicidae)

Mosquito mats with active ingredient d-allethrin (36 mg/mat) and prallethrin (15 mg/mat) were tested in the laboratory against Aedes aegypti (L.) and Culex quinquefasciatus (Say) using test method of the Standard and Industrial Research Institute of Malaysia. Results indicated that KT50 values for d-allethrin against Ae. aegypti and Cx. quinquefasciatus were 1.38 min and 8.36 min, respectively....

Mosquito larvicidal properties of Mirabilis jalapa (Nyctaginaceae) against Anopheles stephensi, Aedes aegypti & Culex quinquefasciatus (Diptera: Culicidae)

Asymmetrical competition and patterns of abundance of Aedes albopictus and Culex pipiens (Diptera: Culicidae).

We tested for competitive advantage among larvae of Aedes albopictus (Skuse) and Culex pipiens L. in a laboratory experiment and determined the frequency and spatial and temporal patterns of co-occurrence in the field in East St. Louis, IL. In a laboratory competition experiment at multiple combined densities of Ae. albopictus and Cx. pipiens larvae, Ae. albopictus survivorship and developmenta...

Effects of different pyrethroids on landing behavior of female Aedes aegypti, Anopheles quadrimaculatus, and Culex quinquefasciatus mosquitoes (Diptera: Culicidae).

Mosquitoes from three genera, Aedes aegypti L., Anopheles quadrimaculatus Say, and Culex quinquefasciatus Say, were tested for facultative landing and resting behavior on pyrethroid-treated surfaces paired with adjacent untreated surfaces. The three pyrethroids tested were bifenthrin, deltamethrin, and lambda-cyhalothrin. Landing and resting behavior was video recorded and quantified using Obse...
