[Post-embrionic development of Stomoxys calcitrans (Linnaeus,1758) (Diptera: Muscidae)feed in feces of treated bovines with different avermectins].
Stomoxys calcitrans is one of the most important ectoparasites of the livestock in Brazil. This dipteran transmits many pathogenic agents to domestic animals, and in Latin America the stable fly is a common vector of Dermatobia hominis eggs. The insecticidal effect of feces from treated bovines with different avermectins was tested against larvae and pupae of S. calcitrans and was studied at the Universidade Federal Rural do Rio de Janeiro. Groups of bovines were, treated with eprinornectin, abamectin, ivermectin and doramectin, and one group was left untreated. Approximatly 100 g of feces was colleted frorn the recturri of each animal at 1, 7, 14, 21 and 28 days post-treatment. The animal feces were mixtured with basic diet 1:1 and inoculated with first instar larvae of S. calcitrans. The results of this trial showed that percentage of viability of S calcitrans, from larvae to adult, was reduced by 85,00; 84,00; 91,00 and 92,00 per cent for eprinornectin, abamectin, ivermectin, and doramectin, respectively after 14 days post-treatment.
