Loss of protection with insecticide-treated nets against pyrethroid-resistant Culex quinquefasciatus mosquitoes once nets become holed: an experimental hut study. [PDF]

, 2008
BACKGROUND: An important advantage of pyrethroid-treated nets over untreated nets is that once nets become worn or holed a pyrethroid treatment will normally restore protection. The capacity of pyrethroids to kill or irritate any mosquito that comes into

First natural occurrence of the entomopathogenic fungus Beauveria bassiana (Bals. Criv.) Vuill. on Cosmopolites sordidus (Germar, 1824) (Curculionidae, Coleoptera) in an agroforestry system in the Brazilian Cerrado [PDF]

Check List
The natural occurrence of the fungus Beauveria bassiana is an indicator of environmental balance. When the agroforestry system naturally presents this entomopathogenic fungus on the banana weevil Cosmopolites sordidus, a pest insect in the banana crops ...

Multiple insecticide resistance mechanisms in Anopheles gambiae and Culex quinquefasciatus from Benin, West Africa.

, 2007
Because free-insecticide treated net distribution is planned in Benin (West Africa) during the next few years, we investigated the type, frequency and distribution of insecticide resistance mechanisms in Anopheles gambiae and Culex quinquefasciatus ...

Effects of osmotic and matric potential on radial growth and accumulation of endogenous reserves in three isolates of Pochonia chlamydosporia [PDF]

, 2009
For the first time, the effects of varying osmotic and matric potential on fungal radial growth and accumulation of polyols were studied in three isolates of Pochonia chlamydosporia.

Real-time quantitative PCR for analysis of candidate fungal biopesticides against malaria: Technique validation and first applications [PDF]

, 2009
Recent research has indicated that fungal biopesticides could augment existing malaria vector control tools. Here we present a set of methodologies to monitor the in vivo kinetics of entomopathogenic fungi in Anopheles in the presence or absence of ...

Evaluation of synthetic repellents on mosquito nets in experimental huts against insecticide-resistant Anopheles gambiae and Culex quinquefasciatus mosquitoes.

, 2006
Owing to the development of pyrethroid resistance in Anopheles gambiae, there is a need to develop chemical alternatives for use on mosquito nets. Synthetic insect repellents are widely used for personal protection as skin or clothing applications.

The entomopathogenic nematode Heterorhabditis megidis: host searching behaviour, infectivity and reproduction [PDF]

, 2001
Entomopathogenic nematodes in the families Heterorhabditidae and Steinernematidae have considerable potential as biological control agents of soil-inhabiting insect pests.

Detection and avoidance of an entomopathogenic fungus by a generalist insect predator

, 2006
1. Increasing evidence suggests that insects can assess their environment based on cues related to mortality risks to themselves or their offspring. Limited knowledge is available on such abilities in relation to entomopathogenic fungi, which can cause ...

Control of pyrethroid-resistant Anopheles gambiae and Culex quinquefasciatus mosquitoes with chlorfenapyr in Benin.

, 2009
OBJECTIVE: To compare the efficacy of chlorfenapyr applied on mosquito nets and as an indoor residual spray against populations of Anopheles gambiae and Culex quinquefasciatus in an area of Benin that shows problematic levels of pyrethroid resistance ...

In vitro assessment of entomopathogenic potential of Clonostachys rosea (Ascomycota: Hypocreales) against Ixodes scapularis (Acari: Ixodidae) and Dermacentor variabilis (Acari: Ixodidae) ticks

Ticks and Tick-Borne Diseases
This study isolated and identified a Clonostachys rosea strain from field-collected tick samples in Nova Scotia, Canada, and investigated its entomopathogenic potential against Ixodes scapularis and Dermacentor variabilis. Ticks were collected from April
