Age-dependent fecundity of Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) with sublethal doses of gammacyhalothrin BABT
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...

Dietary effects upon biological performance and lambdacyhalothrin susceptibility in the multicolored Asian lady beetle, Harmonia axyridis. Repositório Alice
RODRIGUES A. R. dos S.; SPÍNDOLA, A. F.; OLIVEIRA, J. E. de M.; TORRES, J. B..
Considered a generalist species among the coccinellids, the multicolored Asian lady beetle Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) feeds upon small arthropods and non-prey plant products, a practice which might enhance its ability to colonize various ecosystems but carries the potential to expose it to prey quality variation and insecticide use. Thus, we examined the effect of four different diets on the development, reproduction, and response to the insecticide lambda-cyhalothrin in this species. Three groups of larvae received laboratory-reared diets: (i) eggs of Anagasta kuehniella (Zeller) (Ak); (ii) eggs of Sitotroga cerealella (Olivier) (Sc); and (iii) eggs of A. kuehniella + S. cerealella at the proportion 1:1; and one group received...

Insecticide selectivity to the parasitic mite Acarophenax lacunatus (Cross & Krantz) (Prostigmata: Acarophenacidae) on Rhyzopertha dominica (Fabr.) (Coleoptera: Bostrichidae) Neotropical Entomology
Gonçalves,José R.; Faroni,Lêda R.D'A.; Guedes,Raul N.C.; Oliveira,Carlos R.F. de.
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 & 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....

Insecticide susceptibility of horn flies, Haematobia irritans (Diptera: Muscidae), in the State of Mato Grosso do Sul, Brazil. Repositório Alice
BARROS, A. T. M.; GOMES, A,; KOLLER, W. W..
Horn flies from wild populations were collected on cattle and exposed to filter papers impregnated with cypermethrin, permethrin, or diazinon and mortality was assessed after two hours. Resistance to cypermethrin was detected in all populations, with resistance ratios (RR) ranging from 27.6 to 91.3-fold. Permethrin bioassays provided apparently low levels of resistance (RR<5), however, resistant flies were found in 96.9% of the populations based on diagnostic concentrations. From both pyrethroid bioassays, resistance was detected in 97.4% of the populations. On the other hand, a high susceptibility to diazinon (RR d 1.1) was detected in all populations. Pyrethroid products, most cypermethrin (92.3%) and deltamethrin (66.7%), were used in all ranches...

Ocimum basilicum essential oil combined with deltamethrin to improve the management of Spodoptera frugiperda Ciência e Agrotecnologia
Silva,Sérgio Macedo; Cunha,João Paulo Arantes Rodrigues da; Carvalho,Stephan Malfitano de; Zandonadi,César Henrique Souza; Martins,Rafael Castro; Chang,Roberto.
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...

Chernaki-Leffer,Andreia Mauruto; Sosa-Gómez,Daniel Ricardo; Almeida,Lúcia M.; Lopes,Ivani de Oliveira Negrão.
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 Scientia Agricola
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.)...

Synergism of pyrethroids by chlordimeform against susceptible and resistant Heliothis. Repositório Alice
PLAPP JUNIOR, F.W.; CAMPANHOLA, C..
Chlormideform sunergizes synthetic pyrethoids against both Heliothis zea and H. virescens. Synergism is grater against the latter species. The precise mechanism of the synergism is not known but probaly involves target site effects rather than inhibition of metabolism. In preliminary test with pyrethroid resistant insects from western Texas evidence was obtained that chlordimeform was more synergistic with a strain than with laboratory insects.

Toxicity and synergism of insecticides against susceptible and pyrethroid-resistant third instars of the tobacco budworm (Lepidoptera: Noctuidae). Repositório Alice
CAMPAGNOLLA, C.; PLAPP JUNIOR, F. W..
Third-instar tobacco budworms, Heliothis, susceptible or resistant to pyrethroids were tested by exposure to residues of insecticides in glass liquid scintilillation vials. These biossays were done to find alternative insecticides or insecticide combinations for control of larvae resistant to pyrethroids, to evaluate the effect of synergists on insecticide toxicity and resistance, and to establish the main mechanisms of resistance present. Insecticides effective for control of resistant third-instar tobacco budworms included profenofos, sulprofos, acephate, endusulfan, methomyl, and thiodicarb. Cypermethrin combined with chlordimeform, piperonyl butoxide nor chlordimeform produced more thenfive-fold synergism. The only synergistic insecticide combination...

Toxicological effects and resistance to pyrethroids in Boophilus microplus from Goiás, Brazil Arq. Bras. Med. Vet. Zootec.
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,...
