In vitro evaluation of the effects of some acaricides on life stages of Rhipicephalus sanguineus (Acari: Ixodidae) Arq. Bras. Med. Vet. Zootec.
Bicalho,K.A.; Ferreira,F.; Borges,L.M.F.; Ribeiro,M.F.B..
The action of five acaricides was evaluated on eggs, larvae, nymphs and adults of the ixodid tick Rhipicephalus sanguineus. The acaricides tested were: high cis-cypermethrin (0.01%) + DDVP (0.11%), coumaphos (0.05%), deltamethrin (0.0025%), amitraz (0.025%) and cypermethrin (0.015%). Eggs treated with high cis-cypermethrin and cypermethrin showed eclosion inhibitions of 72.1% and 67.3%, respectively, whereas coumaphos was much less effective (only 11.7%). Except for coumaphos, which resulted in 63.3% and 80.0% mortality of nymphs and unfed females, respectively, all compounds tested killed 100% of all tick stages to which they were exposed.

Cyrtoneurina pararescita (Diptera: Muscidae) (Couri, 1995) como novo hospedeiro de Nasonia vitripennis (Walker) (Hymenoptera: Pteromalidae) Arq. Bras. Med. Vet. Zootec.
Marchiori,C.H.; Borges,L.M.F.; Ferreira,L.L..
This study reports the occurrence of Nasonia vitripennis (Walker) (Hymenoptera: Pteromalidae) as parasitoid of Cyrtoneurina pararescita (Diptera: Muscidae) (Couri, 1995) in bovine feces obtained in Goiânia, Goiás state, Brazil. Bovine manure samples, collected at two weeks intervals, were taken to the laboratory and the pupae were extracted by water flotation. Each pupa was placed in capsules of gelatin until the emergence of dipterous or their parasitoids. The parasitism percentage was of 2.4%. This paper reports the first occurrence of N. vitripennis as parasitoid of C. pararescita worldwide.
