The adult flies may emerge from the pupae in as little as seven days during the summer, or after several months over winter. Fruit fly life cycle. Determining the persistence of products in the soil is especially important in the case of those that are directed at pathogens that develop part of their life cycle in the soil, as is the case of the olive fruit fly, whose pupae grow underground. Sweet orange (Citrus sinensis Osbeck) is a highly profitable fruit crop of Nepal. Eggs are white and one millimetre long, which makes them hard to see. There are four stages to the life cycle of fruit flies, these are: eggs, larvae (maggots), pupae and adults. these species • Olive psyllid: a potential threat • Biological control efforts underway ... • The life cycle is about 3 months long depending on temperature • Females may lay more than 1,000 eggs Fruit flies of the species Drosophila melanogaster develop from eggs to adults in eight to ten days at 25 degrees Celsius. The olive fruit fly, Bactrocera oleae (Rossi), is a widespread, monophagous pest that feeds exclusively on wild and cultivated olives (Daane and Johnson 2010).
