Autores: RODRIGUES, S. R.; SANCHES, C. S.; FIALHO, E. M. L. M.; ISMAEL, A. P. K.; BARROS, A. T. M. de.
A mosca-dos-chifres é considerada um sério problema econômico à pecuária devido aos prejuízos causados à produção e gastos com controle. Este estudo objetivou conhecer o perfil da comercialização e uso dos produtos inseticidas para controle da mosca-dos-chifres no município de Aquidauana, MS. De nov/1999 a nov/2000, informações foram obtidas em estabelecimentos agropecuários na cidade de Aquidauana e em entrevistas com produtores rurais e gerentes de fazendas. Um total de 29 produtos indicados para o controle da mosca foram encontrados nos estabelecimentos, pertencentes aos grupos dos piretróides (58,6%), organofosforados (3,4%), fenil pirazoles (3,4%), lactonas macrocíclicas (3,4%) e associações entre inseticidas (31,0%). A cipermetrina foi o princípio...

Multi- and transgenerational effects following early-life exposure of zebrafish to permethrin and coumarin 47: Impact on growth, fertility, behavior and lipid metabolism
Provedor de dados: 5

Transgenerational effects induced by environmental stressors are a threat to ecosystems and human health. However, there is still limited observation and understanding of the potential of chemicals to influence life outcomes over several generations. In the present study, we investigated the effects of two environmental contaminants, coumarin 47 and permethrin, on exposed zebrafish (F0) and their progeny (F1–F3). Coumarin 47 is commonly found in personal care products and dyes, whereas permethrin is used as a domestic and agricultural pyrethroid insecticide/insect repellent. Zebrafish (F0) were exposed during early development until 28 days post-fertilization and their progeny (F1–F3) were bred unexposed. On one hand, the effects induced by coumarin 47...

Insecticide selectivity to the parasitic mite Acarophenax lacunatus (Cross &amp;amp; Krantz) (Prostigmata: Acarophenacidae) on Rhyzopertha dominica (Fabr.) (Coleoptera: Bostrichidae)
Provedor de dados: 82

The presence of natural enemies in stored grains and the need of pest control alternatives led to the assessment of the effect of insecticides on the mite species Acarophenax lacunatus (Cross &amp;amp; Krantz), an egg parasite of the stored grain pest Rhyzopertha dominica (Fabr.). The insecticides bifenthrin, deltamethrin, pirimiphos-methyl and fenitrothion were tested at 0.4, 0.5, 0.8 and 10 ppm, respectively. Insecticide treated wheat grains were spread in petri dishes and infested with 25 adults of R. dominica. Seven days later, three mites were added to each dish, in four replicates. The number of adults of R. dominica, grain weight loss and instantaneous rate of increase (r i) of A. lacunatus were lower when the grain was treated with deltamethrin....

Susceptibility of Alphitobius diaperinus (Panzer) (Coleoptera, Tenebrionidae) to cypermethrin, dichlorvos and triflumuron in southern Brazil

Susceptibility of Alphitobius diaperinus (Panzer) (Coleoptera, Tenebrionidae) to cypermethrin, dichlorvos and triflumuron in southern Brazil. The lesser mealworm, Alphitobius diaperinus (Panzer), is an important insect pest in poultry houses in Brazil. Susceptibility of the lesser mealworm collected from eight poultry houses in Paraná state, southern Brazil, was evaluated for cypermethrin, dichlorvos and triflumuron. Adult A. diaperinus were tested in bioassays with cypermethrin and dichlorvos. Larvae were fed rabbit feed wetted with a triflumuron-water solution. Concentration-mortality regressions were estimated using Probit analysis and resistance ratios were calculated based on the susceptible population. Among the field populations evaluated,...

Susceptibility of Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidea) to gamma-cyhalothrin under laboratory conditions
Provedor de dados: 63
Autores: Pereira,Alexandre Igor de Azevedo; Ramalho,Francisco de Sousa; Zanuncio,José Cola.
Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) is an important biological control agent of the cotton leafworm [Alabama argillacea (Hübner)] in the cotton crops in Brazil. The use of selective products such as pyrethroids has been emphasized in this agroecosystem. Then, the susceptibility of the predatory stinkbug P. nigrispinus to the pyrethroid insecticide gamma-cyhalothrin was studied in the laboratory. Nymphs and adults of the predator were exposed to seven concentrations of the gamma-cyhalothrin via topical contact and ingestion through treated water. The concentrations studied of this insecticide via topical application were relatively harmless for adults of P. nigrispinus (females: LC50 = 143.5 ppm a.i., and males: LC50 = 145.1 ppm a.i.)...

Toxicological effects and resistance to pyrethroids in Boophilus microplus from Goiás, Brazil
Provedor de dados: 45
Autores: Fernandes,F.F.
In order to monitor the susceptibility of Boophilus microplus to acaricides and improve control measures, the effects of cypermethrin, deltamethrin and permethrin on larvae obtained in the city of Goiânia in the Brazilian state of Goiás were studied. Although these pyrethroids are already sold as acaricides, their cost-benefit efficiency has been questioned. Fasting 14-21 day-old larvae were immersed in solutions of the acaricides under test, maintained at 27±1° C, and relative humidity over 80%, and observed under the stereoscope within an apparatus originally designed for studying the non-parasitic phase of the tick life cycle. The observed toxicological effects were: excitability, repetitive motion, decreased motor ability, detachment, paralysis,...

Age-dependent fecundity of Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) with sublethal doses of gammacyhalothrin
Provedor de dados: 52
Autores: Pereira,Alexandre Igor Azevedo; Ramalho,Francisco de Sousa; Bandeira,Catarina de Medeiros; Malaquias,José Bruno; Zanuncio,José Cola.
Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) was exposed to gammacyhalothrin to study the stimulatory effect of low concentrations of this pyrethroid. The doses studied were 23.4375, 11.7188, 5.8594, 2.9297, 1.4648, 0.7324 mg.litre-1 and water, as control. The third, fourth, and fifth instars of P. nigrispinus were shorter with all the doses of this insecticide. The survival and longevity of this predator was highest with the lowest doses. The oviposition period of P. nigrispinus decreased as the doses increased. The lowest pre-and postoviposition periods were found with 11.7188 mg.litre-1 of gammacyhalothrin. The dose 0.7324 mg.litre-1 increased the clutch interval. The egg viability was similar between the treatments. The number of eggs per...

Ocimum basilicum essential oil combined with deltamethrin to improve the management of Spodoptera frugiperda
Provedor de dados: 64

ABSTRACT For an important and expensive crop such as corn, the resistance of Spodoptera frugiperda J.E. Smith to various pesticides has led to research throughout the world for a potential insecticide from a natural source. For the management of pest resistance, natural compounds associated with synthetic insecticides can be a promising tool because they can reduce the application of the synthetics molecules while maintaining their effectiveness and promoting the control of the pests. Linalool is a potential insecticide that is easily obtained because it is found in high concentrations in the essential oil of Ocimum basilicum L. Therefore, the present study aimed to evaluate the toxicity of this essential oil and its combination with deltamethrin to...
