Abstract
The purpose of this study was to evaluate the survival, development time and morphological measures of immature Ophyra aenescens and Ophyra albuquerquei on different diets. Different proportions of protein and carbohydrates were offered for each species in 10 vials containing 30 eggs each. The vials were placed in a germination chamber at 30°C, relative humidity above 75% and photoperiod of 12 hours. Every day a vial was removed and mortality was evaluated and on the tenth day the length of the cephalic-pharyngeal skeleton (EC) and body size (G) of larvae that survived were evaluated. Survival was higher in diets with more protein (P<0.001). Between the species, mortality was more pronounced in O. albuquerquei in all diets (P<0.001). The EC (P<0.01) and G (P<0.01) showed the same sizes in the diets with higher protein content. For the production of pupae of these species, the diet with more protein and fewer components is more appropriate, and the production is higher in O. aenescens than in O. albuquerquei.
Highlights
The Ophyra Robineau-Desvoidy, 1830 (Diptera, Muscidae) species are used in the biological control of Musca domestica L., 1758 (Diptera, Muscidae) in poultry and pig farms in the United States and Europe (Farkas et al, 1998; Hogsette and Jacobs, 1999), which can be used in production systems for dairy cattle (Hogsette et al, 2002)
The survival of the O. aenescens and O. albuquerquei larvae was higher in diets with more protein than diets with more carbohydrates ( 2=390.48, DF=7, P
The mean mortality time in the diets ranged from 8 to 16 days for O. aenescens and 6 to 10 days for O. albuquerquei according to the estimated models (Table 3)
Summary
The Ophyra Robineau-Desvoidy, 1830 (Diptera, Muscidae) species are used in the biological control of Musca domestica L., 1758 (Diptera, Muscidae) in poultry and pig farms in the United States and Europe (Farkas et al, 1998; Hogsette and Jacobs, 1999), which can be used in production systems for dairy cattle (Hogsette et al, 2002). The purpose of this study was to investigate the influence of different proportions of protein and carbohydrates on survival, development, and size of Ophyra aenescens (Wiedemann, 1830) and Ophyra albuquerquei Lopes, 1985 larvae’s. The O. aenescens and O. albuquerquei larvae were fed according to Ribeiro et al (2000b) and Kruger et al (2003) modified from Hogsette and Washington (1995) and Farkas et al (1998), who used Gainesville and Budapest diets for larvae.
