Bioassay method for toxity studies of toxic bait formulations to ceratitis capitata (Diptera: Tephritidae). Repositório Alice
BARÔNIO, C. A.; BERNARDI, D.; NUNES, M. Z.; PASINATO, J.; GARCIA, F. R. M.; BOTTON, M..
The development of appropriate methodologies for bioassays is of paramount importance to study the methodological factors that may interfere in the experimental design. Thus, laboratory bioassays have become increasingly important for the determination of data that are realistic and replicable. The objective of the study was to develop a bioassay methodology with the ready-to-use toxic bait Success ? 0.02CB, 96 mg L−1 of spinosad, in adults of Ceratitis capitata (Wiedemann) as a study model. The insect origin laboratory population, LT 50= 11.16 h), time of toxic bait supply (4 h, LT 50= 16.85 h), food deprivation (12 h, LT 50= 15.55 h), and the adult age (5 days, LT 50= 35.31 h) of C. capitata showed higher susceptibility and a shorter LT 50...

Effects of some Insecticides Applied in Sublethal Concentrations on the Survival and Longevity of Aphidius ervi (Haliday) (Hymenoptera: Aphidiidae) Adults Chilean J. Agric. Res.
Araya,Jaime E.; Araya,Manuel; Guerrero,María Angélica.
The effects of four insecticides (dimethoate, pirimicarb, imidacloprid, and spinosad) applied in an ST4 Potter tower at sublethal concentrations (50% of those recommended commercially for aphid control) were studied in the laboratory on aphidiid Aphidius ervi (Haliday) adults, an important parasitoid of the pea aphid Acyrthosiphon pisum (Harris). The most selective treatment on the hymenopteran was imidacloprid, followed in decreasing order by spinosad, pirimicarb, and finally dimethoate, which quickly eliminated the parasitoid and thus its capacity to produce progeny. Three toxicity groups were distinguished in the study. The least damaging treatment to adults of A. ervi was imidacloprid, followed by a group of medium toxicity made up of spinosad and...

Efficacy of bio-insecticides on Tuta absoluta (Meyrick) (Lep.: Gelechiidae) in laboratory and field conditions CIGR Journal
Hosseinzadeh, Abbas; Aramideh, Shahram; Ghassemi-Kahrizeh, akbar.
Tuta absoluta (Meyrick) is a devastating pest of tomato. This pest is becoming resistant to many of the pesticides that used in the tomato fields. In this research, the efficacy of four bio-insecticides namely, thiocyclam, spinosad, Bacillus thuringiensis and azadirachtin (Azadirachta indica) were studied on the tomato leaf miner in the laboratory and field conditions. Laboratory experiments were performed in a randomized complete plot design with three replications against 1st, 2nd and 3rd larvae. Field experiment was carried out on three larval stages based on recommended doses of pesticides in the form of a completely randomized block. The results showed that in laboratory conditions, LC50 values and lower and upper bond with 95% confidence limits of...

Laboratory evaluation of the effects of Attract & Kill formulations on Anastrepha Fraterculus. Repositório Alice
BORGES, R.; BOTTON, M.; MACHOTA JUNIOR, R.; BOFF, M. I. C.; MAFRA-NETO, A..
A new atract & kill (A&K) formulation was dcveloped by ISCA Tccnologias to control fruit flies, In laboratory tests, we compared the efficacy of this new formulation with three cornrnercial products used by fruit growers in southern Brazil. Mortality tests were performed with Anastrepha fraterculus (Diptera: Tephntidae) and results showed that the effecuveness of Anarosa forrnulations was directly proportional to increasing dose of insecticide. Formulations containing organophosphates and cypennethrin produced similar mortality results. The Anarosa formulations, regardless of the insecticide dose, were more effective than GF 120 for A, fraterculus control.

Population suppression of Ceratitis capitata (Wiedemann) on table grapes using toxic baits. Repositório Alice
BARÔNIO, C. A.; BERNARDI, D.; PARANHOS, B. A. J.; GARCIA, F. R. M.; BOTTON, M..
To provide alternatives to the use of spraying synthetic insecticides in C. capitata management, was evaluated the effect of ?attract and kill? toxic baits on population suppression of C. capitata in three commercial areas producing table grapes. Toxic baits of Gelsura? (4.5 L ha-1) and Success? 0.02 CB (4.0 L ha-1) resulted in lower population levels of C. capitata adults in monitoring traps after five sequential applications at weekly intervals during the maturation period of the grapes when compared with control plots with or without insecticidal spray. In addition, plots with Gelsura? and Success? 0.02 CB applications showed a significant reduction in damage (%) by C. capitata on grape berries and grape bunches when compared with control plots without...

La susceptibilidad del trips de California, Frankliniella occidentalis (Pergande) a formetanato (Dicarzol 500 SP), metamidofos (Tamaron 600 SL), dimetoato (Perfekthion) y spinosad (Success 48) fue evaluada utilizando concentraciones seriadas asperjadas con la Torre de Potter, sobre hojas de frejol. En los bioensayos fueron utilizadas hembras adultas provenientes de tres localidades de la V Región (Ocoa 32º55’ lat. Sur, 71º05’ long. Oeste; 365 m.s.n.m.; Auco 32º52’ lat. Sur; 70º40’ long.
