Dietas artificiais para Ceratitis capitata (Diptera: Tephritidae) sob diferentes densidades de ovos

Abstract

The species Ceratitis capitata (Diptera: Tephritidae) is one of the main pests of fruit growing worldwide, it is highly polyphagous, warning about food safety. Control methods for this pest require laboratory studies and a large number of insect pests. The mass rearing of this insect is carried out on artificial diets, however, the carrying capacity of each diet is important to quantify the maintenance cost of the creation. Thus, this work aims to evaluate the efficiency of different densities of eggs in artificial diets. Different densities of eggs (50; 75; 100; 125; 150) of C. capitata were inoculated in artificial diets based on carrot, pumpkin and sweet potato. In addition, interference of biological characteristics of C. capitata, such as larval length and pupal weight and sex ratio, of larval, ovo-pupa and egg-adult times. The results show that the use of sweet potato leads to longer times of two biological parameters, in developing diets based on carrots lead to a reduction in these times and greater viability. The results show that the use of sweet potato leads to longer times for biological parameters, in contrast to the development of a diet based on carrots, the reduction of these times and greater pupal viability. The use of the density of 150 eggs in the pumpkin-based diet is an alternative to reduce rearing costs, without reducing the quality of the biological parameters of insect pests.
