Mating produces profound changes in the behavior of female flies, such as an increase in
oviposition, reduction in sexual receptivity, increase in feeding, and even excretion. Many of …

The family Tephritidae (Diptera) comprises over 4000 species of which c. 250 belong to the
genus Anastrepha. Of these, fewer than ten species are considered to be economically …

Until 30 years ago, the emphasis on reproductive costs for males was mainly on costs
related to mate searching, courtship and fighting with rival males. However, costs for males …

Recent recognition of widespread polyandry in insects has generated considerable interest
in understanding why females mate multiple times and in identifying factors that affect …

The inhibition of female receptivity after copulation is usually related to the quality of the first
mating. Males are able to modulate female receptivity through various mechanisms. Among …

In polygynous insect species, male reproductive success is directly related to lifetime mating
success. However, the costs for males of sexual activities such as courting, signaling, and …

Male insects that are unable to replenish sperm supplies between matings can suffer fitness
costs either because their mates are more likely to accept subsequent suitors, or because …

Male age and sexual experience are important condition parameters that can influence mate
choice and female fitness, yet they are seldom studied simultaneously. Here, we …

In lekking species, females may become sperm-limited when mating with sexually
successful males, and this may be exacerbated by a poor male diet. Polygynous males may …

One of the most humbling challenges a fruit-fly biologist can face is to try to understand what
drives the biology, ecology and behaviour of fruit flies and, based on this knowledge, design …
