Is the insect world overcoming the efficacy of bacillus thuringiensis?
(MDPI AG, 2017-01-18)
The use of chemical pesticides revolutionized agriculture with the introduction of DDT (Dichlorodiphenyltrichloroethane) as the first modern chemical insecticide. However, the effectiveness of DDT and other synthetic ...
Deltamethrin-resistant German Cockroaches Are Less Sensitive to the Insect Repellents DEET and IR3535 than Non-resistant Individuals
(Oxford University Press, 2018-04)
The German cockroach, Blattella germanica (L.) (Blattodea: Blattellidae), is a serious worldwide pest with a considerable economical and sanitary impact. It is mainly controlled by the application of synthetic insecticides, ...
Environmental and genetic control of insect abundance and herbivory along a forest elevational gradient
(Springer, 2011-04)
Environmental conditions and plant genotype may influence insect herbivory along elevational gradients. Plant damage would decrease with elevation as temperature declines to suboptimal levels for insects. However, host ...
Silica nanoparticles for insect pest control
(Bentham Science Publishers, 2019-10)
To date, control strategies used against insect pest species are based on synthetic insecticide applications. In addition, the efficacy of these treatments could be decreased due to insecticide resistance in insect ...
Neuroethology of olfactory-guided behavior and its potential application in the control of harmful insects
(Frontiers Research Foundation, 2016-06)
Harmful insects include pests of crops and storage goods, and vectors of human and animal diseases. Throughout their history, humans have been fighting them using diverse methods. The fairly recent development of synthetic ...
Toxicity of pyrethroids and repellency of diethyltoluamide in two deltamethrin-resistant colonies of Triatoma infestans Klug, 1834 (Hemiptera: Reduviidae)
(Fundação Oswaldo Cruz, 2006-02)
The aim of the currrent investigation was to evaluate (a) the toxicity of three pyrethroids (deltamethrin, lambdacyhalothrin, and tetramethrin); (b) the effect of these insecticides on the locomotor activity; and (c) the ...
Increased Monooxygenase Activity Associated with Resistance to Permethrin in Pediculus humanus capitis (Anoplura: Pediculidae) from Argentina
(Entomological Society of America, 2005-05)
We studied the profile of permethrin resistance in head lice populations infesting children 6-12 years old in schools and children´s homes in & around Buenos Aires, Argentina. Five permethrin resistant populations with ...
Characterization of components of resistance to Corn Stunt disease
(Public Library of Science, 2020-10)
Corn Stunt is an important disease in the Americas due to it high prevalence and the yield reductions that can cause when present. However, changes in the presence of this disease across years hampers the effective ...
Resistance to deltamethrin in Triatoma infestans: microgeographical distribution, validation of a rapid detection bioassay and evaluation of a fumigant canister as control alternative strategy
(Cambridge University Press, 2020-10)
Triatoma infestans (Klug) (Hemiptera: Reduviidae) is the main vector of Chagas disease in the Southern Cone of America and resistance to pyrethroid insecticides has been detected in several areas from its geographical ...
Effect of reproductive state on active dispersal in Triatoma infestans (Klug, 1834)(Hemiptera: Reduviidae: Triatominae) susceptible and resistant to deltamethrin
(Elsevier Science, 2019-08)
Triatoma infestans (Klug, 1834)is the main vector of the Chagas´ disease in Argentina. The presence of insects in the domestic environment after application of pyrethroid insecticides was reported. The colonization and the ...
