“…Our findings for etofenprox are similar to those of Giolo et al (2006;2008), who studied the effect of this insecticide (0.015 g ai L -1 ) on T. pretiosum and Trichogramma atopovirilia Oatman & Platner, 1983 (egglarval, pre-pupal, and pupal stages) and verified that the emergence of F1 adults of both species was not affected by the insecticide, regardless of the immature stage studied, considering it harmless (class 1) to this beneficial.…”

Fall armyworm Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae) is an important pest of maize (Zea mays L.) crops in Brazil. The effects of beta-cypermethrin, chlorfenapyr, chlorpyrifos, spinosad, etofenprox, triflumuron, alpha-cypermethrin/teflubenzuron, and lambda-cyhalothrin/thiamethoxam on Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae) immature stages were evaluated. Eggs of Anagasta kuehniella (Zeller, 1879) (Lepidoptera: Pyralidae), containing immature stages of the parasitoid were dipped in water solution pesticides, to evaluate their effects on emergence and sex ratio of F1 parasitoids. For F2 parasitoids, emergence, parasitism capacity, and sex ratio were evaluated. Beta-cypermethrin, chlorfenapyr, chlorpyrifos, and spinosad affected the emergence success of F1 T. pretiosum. Insects exposed to etofenprox and alpha-cypermethrin/teflubenzuron during the egg-larval period and to lambda-cyhalothrin/thiamethoxam during the pupal stage also suffered reduction in the emergence. Beta-cypermethrin affected the sex ratio of F1 T. pretiosum from host eggs treated during the egg-larval period; spinosad affected it during the egg-larval period and the pupal stage, whereas chlorpyrifos did the same when applied during the pupal stage. Chlorpyrifos also affected the sex ratio of F2 parasitoids, but only when applied during the egg-larval period, whereas chlorfenapyr reduced this trait when applied during the pre-pupal phase. Chlorpyrifos and alpha-cypermethrin/teflubenzuron affected the parasitism capacity of F1 females from eggs treated during the egg-larval period. Considering the overall effects, only etofenprox and triflumuron were selective on T. pretiosum when applied on parasitized A. kuehniella eggs. Further studies need to be carried out to verify the toxicity of the other pesticides under semi-field and field conditions.

“…In the few studies of the effects of glufosinate ammonium on egg parasitoids, this herbicide was generally reported to adversely affect these parasitoids, although the effects are typically moderate . These results align with observations on immature stages and previously on adults of T. pretiosum .…”

“…Entretanto, apesar dos dois produtos avaliados (acetamiprido e etofenproxi) estarem na mesma classificação toxicológica III, deve-se considerar a dose recomendada e o seu grupo químico. A dose de acetamiprido recomendada é menor que a do etofenproxi (6 g i.a./100L e 12 g i.a./100L, respectivamente) e estudos indicam que o acetamiprido é menos agressivo aos inimigos naturais que o etofenproxi (Tanaka et al, 2000;Santolamazza-Carbone & Fernández de Ana-Magán, 2004;Poletti et al, 2007;Giolo et al, 2008). Portanto, dentre os produtos avaliados, o tratamento que apresenta melhor eficiência de controle de C. capitata na cultura da manga com menor impacto ambiental foi o acetamiprido na dose de 6 g i.a./100L.…”

Efficiency of Etofenprox and Acetamiprid on Mediterranean fruit fly Ceratitis capitata (Diptera:Tephritidae) in Mango Orchard ABSTRACT -Tephritidae fruit flies are considered key pests in mango crop, leading to economic damages, requiring control actions and imposing quarantine constraints to the international fresh fruits trade. In the present study it was evaluated the efficiency of etofenprox and acetamiprid in three dosages for controlling medfly (Ceratitis capitata) in mango orchard. The assay was carried out in a commercial orchard of Tommy Atkins cultivar, located in Petrolina in the state of Pernambuco, as soon as the harvest had finished. The insecticides and respective doses evaluated were: acetamiprid 4, 6 e 8 g a.i./100L; etofenprox 6, 12 e 18 g a.i./100L; fenthion 50 g a.i./100L. The products were sprayed only once, baited with water and sugar cane molasses as food attractive. The efficiency was evaluated scoring the number of males medfly caught in Jackson traps and calculating the efficiency % by Henderson & Tilton's equation. The traps were exposed for 24 h on the 1st, 2nd, 3rd, 7th, 10th and 15th day after spraying. Acetamiprid 6 g a.i./100L 8 g a.i./100L; etofenprox 12 g a.i./100L, 18 g a.i./100L and fenthion 50 g a.i./100L presented efficiency higher than 80%. Among them, acetamiprid 6 g a.i./100L performed the greatest value (93.14%) and higher stability along the time. Thus, the acetamiprid can be applied, baited with a food lure, for controlling medfly in mango orchards after achievement the suitable register in Brazil.
