          Abstract

          Stomoxys calcitrans (Linnaeus, 1758) (Diptera: Muscidae) é conhecida por sua dolorosa picada, que causa estresse nos animais, e pela transmissão de diversas enfermidades, além de atacar o homem. Devido aos surtos ocorridos em áreas sucroalcooleiras no Brasil, onde o vinhoto é utilizado na fertirrigação dos canaviais, elaborou-se o presente estudo, que teve como objetivo verificar se o vinhoto favorece a postura e o desenvolvimento dos estádios imaturos desse inseto. Para tanto, ovos foram depositados em dieta de crescimento larval de Bailey (controle) e também em dietas com substituição de 5, 10, 20 e 30% do seu volume de água por vinhoto. Parte dos resultados foi submetida à analise de variância e as médias foram comparadas entre si pelo teste de Tukey. A outra parte foi avaliada pelo teste do Qui Quadrado. A viabilidade dos ovos foi de 66%, 64%, 69%, 80% e 20% das larvas de 96,4%, 96,9%, 95,1%, 99,3% e 97,2% e das pupas de 90,2%, 94,7%, 93,5%, 91,5% e 86,1%, respectivamente, para os grupos controle, 5, 10, 20, e 30%. O peso das larvas de terceiro estágio foi de 16,4; 16,9; 19,7; 15,8 e 18mg, e das pupas foi 12,9; 13,9; 17,4; 14,5 e 21,9mg. O período larval foi de 10,38, 11,81, 10,00, 10,86, 9,5 dias, e o pupal foi de 6,57; 6,19; 7,05; 7,00 e 6,00, respectivamente. A viabilidade dos estádios imaturos foi maior nas dietas com substituição de vinhoto. Algumas concentrações de vinhoto utilizadas nas dietas afetaram a biologia dos estádios imaturos de S. calcitrans.

          Stomoxys calcitrans is known for its painful sting that causes stress in animals and also by transmitting several diseases, and attack man. Due to the outbreaks in sugarcane fields in Brazil, where the vinasse is used in fertigation of the sugarcane fields, this study was conducted, aiming to verify if the vinasse would improve posture and development of the immature stages of this insect. 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, and the other, was assessed by Chi-square. The eggs viability was of 66%, 64%, 69%, 80% e 20%, the larvae was of 96.4%, 96.,9%, 95.1%, 99.3% e 97.2% and the pupae was of 90.2%, 94.7%, 93.5%, 91.5% and 86.1%, respectively to the control, 5, 10, 20, e 30%. The weight of the third stage larvae was 16.4; 16.9; 19.7; 15.8 and 18mg, and pupae was of 12.9; 13.9; 17.4; 14.5 e 21.9mg. The larval period was of 10.38, 11.81, 10.00, 10.86, 9.5 days, and the pupal was of 6.57, 6.19, 7.05, 7.00 and 6.00 days, respectively. The viability of the immature stages was higher in diet with replacement of vinasse. Some of vinasse concentrations used in diets affected the biology of immature stages of S. calcitrans.
