Impact of Insecticide Resistance on the Effectiveness of Pyrethroid-Based Malaria Vectors Control Tools in Benin: Decreased Toxicity and Repellent Effect.

open access: yesPLoS ONE, 2015
Since the first evidence of pyrethroids resistance in 1999 in Benin, mutations have rapidly increased in mosquitoes and it is now difficult to design a study including a control area where malaria vectors are fully susceptible.

Cellular immune response of Amblyomma sculptum and Amblyomma americanum to entomopathogenic fungi: Implications for biological tick control

open access: yesMedical and Veterinary Entomology, EarlyView.
Amblyomma sculptum showed a plasmatocyte‐dominant haemocyte profile. Beauveria bassiana increased plasmatocytes and reduced granulocytes, whereas Metarhizium robertsii did not cause significant changes. Amblyomma americanum showed a granulocyte‐dominant haemocyte profile. Beauveria bassiana reduced total haemocytes and granulocytes. B.

Indoor residual spraying of distinct insecticide formulations in a household‐scale micro‐mosaic format: Feasibility and effectiveness for malaria vector control in rural Zambia

open access: yesMedical and Veterinary Entomology, EarlyView.
Densities of all Anopheles species were approximately comparable across all IRS regimes. No differences observed between treatment regimes regarding species composition of the Anopheles funestus group or An. gambiae complex. This operational pilot demonstrates the practical feasibility of IRS micro‐mosaics, despite the inherent increase in deployment ...

The Contribution of Entomological Surveillance to the Control of Chagas Disease in Endemic Regions: An Integrative Literature Review

open access: yesTropical Medicine &International Health, EarlyView.
ABSTRACT Chagas disease remains a significant public health challenge in various endemic regions of Latin America. The persistence of vector‐borne transmission highlights the complexity of the issue and the limitations of traditional strategies. In this context, entomological surveillance plays a strategic and multifaceted role, not only in the early ...

Activity and Residual Effect of Two Formulations of Lambdacyhalothrin Sprayed on Palm Leaves to Rhodnius prolixus

open access: yesMemorias do Instituto Oswaldo Cruz, 2002
The insecticidal activity and residual effect of two formulations of lambdacyhalothrin were evaluated with Rhodnius prolixus;laboratory and field tests were conducted in the State of Chiapas, Mexico. The results indicate that the lethal concentrations of

Susceptibility of Phthorimaea absoluta (Meyrick) (Lepidoptera: Gelechiidae) to novel and established insecticides in Brazil: resistance survey, baseline, and implications for management

open access: yesPest Management Science, Volume 82, Issue 6, Page 5662-5671, June 2026.
Baseline susceptibility of Phthorimaea absoluta to novel insecticides isocycloseram and tolfenpyrad was established in Brazil. Diagnostic doses were proposed for early resistance detection. Early tolfenpyrad tolerance and abamectin‐driven cross‐tolerance to isocycloseram via oxidases highlight cross‐resistance risks, emphasizing the need for routine ...

Control failure risk, resistance and enzymatic activity of neurotoxic insecticides in Brazilian populations of Leucoptera coffeella (Lepidoptera: Lyonetiidae)

open access: yesPest Management Science, Volume 82, Issue 6, Page 5757-5766, June 2026.
Bioassays of 36 Leucoptera coffeella populations revealed resistance to neurotoxic insecticides, control failures of ≤62.9% and enzyme activity variation, with particularly high GST and low AChE levels. Abstract Background Leucoptera coffeella is a key pest of coffee crops in Brazil, causing significant damage by mining coffee leaves.

Leaf Extracts of Coffea racemosa Inhibit Trypsin Activity and Affect Larval Development in Spodoptera frugiperda and Diatraea saccharalis

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 6, Page 527-535, June 2026.
Leaf extracts of Coffea racemosa inhibit digestive trypsins and impair the development of two major lepidopteran pests, Spodoptera frugiperda and Diatraea saccharalis. While both species showed significant enzymatic inhibition, biological responses differed markedly. D. saccharalis exhibited high mortality, whereas S.

Fertility and life expectancy of the predator Supputius cincticeps (Heteroptera: Pentatomidae) exposed to sublethal doses of permethrin

open access: yesBiological Research, 2005
The stinkbug Supputius cincticeps (Stål) (Heteroptera: Pentatomidae) can be found in agricultural and forest ecosystems feeding primarily on larvae of Coleoptera and Lepidoptera, where it can be exposed to insecticide applications.
