Abstract
The study showed that the nutritional content
of fruits affects the growth of adult flying insects and their larval stages,
and given the importance of fruit flies, represented by both the (Bactrocera
zonata and Ceratitis capitata).Infecting fruits during the
physiological maturity stage of fruits, especially with the presence of mixing
in horticultural crops, especially in rural Egypt, this may lead to the
settlement of flies inside old horticultural farms.Therefore, the study focused
on the fruit content of proteins, fats, and carbohydrates necessary for the
growth of larvae of the peach and fruit flies in each of the fruits under
study, which are (Guava - Mango - Peaches).The results also showed that the
competitive dominance of Bactrocera zonata larvae over Ceratitis
capitata larvae, with both flies preferring Guava fruits with the presence
of both Peach and Mango fruits. It was also shown that peach fly larvae prefer
the fat and carbohydrate content of the fruit content, while the fruit fly
larvae prefer the protein content. There was also a strong significant
correlation between fruit content and the growth of larvae at their three ages
inside the fruit, while the relationship was direct between the larvae of the
two flies. It has also been shown that the relationship between the larvae of
the two flies and protein was a positive, direct relationship. Increasing the
protein component in the fruits leads to an increase in the growth of the
larvae in their three stages of life. While the inverse relationship was
negative between the growth of the larvae of the two flies, thus the growth of
the Bactrocera zonata larvae prevails over the growth of the Ceratitis
capitata larvae because the Ceratitiscapitata larvae need about
twice the nutritional requirement of the Bactrocera zonata larvae in
terms of proteins. While the biochemical analysis of the pupal stage of the two
insects indicated to that there were no significantly differences between them
in protein and lipids.
