Stomoxys calcitrans is known for this painful sting that causes stress in animals, transmission of several diseases, and also attack man. Due to the outbreaks in sugarcane fields in Brazil, where the vinasse is used in fertigation of the sugarcane fields, was conducted this study, which aimed to verify if the vinasse would improve posture and the development of the immature stages of this dipterous. For this, eggs were deposited into diet of larval growth of Bailey (control), and also in diets with replacement of 5, 10, 20 and 30% of this water volume per vinasse. Part of the results was submitted to analysis of variance and means were compared by Tuket test, regressions and correlations, and the other, was assessed by Chi-square. The eggs viability was 66%, 64%, 69%, 80% e 20%, the larval was 96,4%, 96,9%, 95,1%, 99,3% e 97,2% and the pupae was 90,2%, 94,7%, 93,5%, 91,5% e 86,1%, to the control, 5, 10, 20, e 30%. The weight of the third stage larvae was 16,4; 16,9; 19,7; 15,8 e 18 mg, and pupae was 12,9; 13,9; 17,4; 14,5 e 21,9 mg, to the control, 5, 10, 20, e 30%. The period larval was 10,38, 11,81, 10,00, 10,86, 9,5 days, and the pupal was 6,57, 6,19, 7,05, 7,00 e 6,00 days. To evaluate the effect of vinasse on the oviposition of S. calcitrans, it was used 15 cages with vinasse in Petri dishes and other 15 with only water. In each cages were inserted one female and two male. Females kept isolated in cages without vinasse, eight laid eggs with an average of 32.3 eggs and in the cages with vinasse, six laid, with an average of 41.5 eggs. The viability of the immature stages was higher in diet with replacement of vinasse, however the vinasse did not affect the oviposition of females, although fewer females had laid more eggs. Depending on the concentration used in the diet, the vinasse affected negatively or positively or even did not influence the biology of immature stages of S. calcitrans. |
