“…We do not really know if this sustained copulation in N. cyanescens is necessary to complete transfer of sperm or is imposed by males to prevent the female from mating with other males and subsequent sperm precedence. In C. capitata , sperm from second‐mating males have a genetic predominance in the offspring ( Saul et al . 1988 ).…”

We describe the diurnal temporal and spatial patterns of reproductive activities (mating and ovipositing) of adult tomato fruit¯ies, Neoceratitis cyanescens (Bezzi) (Diptera: Tephritidae), under laboratory, ®eld-cage and ®eld conditions. The distribution pattern of¯ies in the different habitats (host and nonhost plants) showed temporal, physiological and sexual differences. Mature females were observed to frequent host plants preferentially, particularly in the late afternoon. By contrast, immature females preferred to rest on non-host plants throughout the day. Males frequented mainly non-host plants but some were observed on host fruits in the morning. Mating activity took place preferentially on non-host plants, in the morning. In laboratory cages, females showed a strong daily propensity to engage in mating behaviour; the mean percentage of mating females was 88 6 5%. Time allotted to this activity (4 h 52 min 6 1 h 23 min in laboratory cages and at least 3 h for the mating pairs observed in the ®eld) appeared considerable compared to the time required to satisfy feeding or oviposition activities. Except for a few ovipositing females observed in the morning, oviposition activities occurred mainly in the late afternoon.

“…Some early indications are available in the literature from studies of two tephritids from different genera. Using pupal colour markers, Saul et al (1988) found evidence that in C. capitata second male sperm precedence tends to predominate paternity overall, but that a longer first copulation results in greater contribution of the first male to paternity (r = 0.87 and 0.83 for two male pupal colour strains). Using electrophoresis to establish paternity of twice-mated females in three groups of 5, 6 and 8 families, Opp et al (1990) found paternity of the second mate in R. pomonella to be weakly correlated with first mate copula (r = 0.20, 0.07, 0.23) but very strongly correlated with second mate copula duration (r = 0.47, 0.75, 0.63).…”

“…The level of polyandry seems to result from the balance between costs and benefits and ranges from monogamy to high promiscuity (Torres‐Vila, Rodriguez‐Molina, & Jennions, ). Nonetheless, several factors have been reported to affect female remating frequency, such as first copula duration (Farias, Cunningham, & Nakagawa, ; Saul, Tam, & McInnis, ), nutritional status (Blay & Yuval, ), strain (Vera, Wood, Cladera, & Gilburn, ) and male sterilization (Abraham, Cladera, Goane, & Vera, ; Gavriel, Gazit, & Yuval, ; Katiyar & Ramirez, ). In fact, products in seminal fluids may act as potent inhibitors of female remating (Radhakrishnan & Taylor, ).…”

Female remating is a widespread behaviour, reported in several insect species. This behaviour can affect the efficiency of sterile insect technique (SIT); however, little is known about the postcopulatory behaviour of some pest species considered as candidates to be controlled by this technique, such as Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae). In this study, we investigated the effects of male and female sterilization on mating and remating behaviour of D. suzukii. First, we tested the occurrence of multiple mating in different combinations between sterile and fertile males and females. Then, we tested the effects of male and female sterility on female propensity to mate and remate. We found an overall low remating rate by D. suzukii females. Male sterility did not influence mating and remating likelihood; however, copula duration of sterile males was shorter compared to fertile males. On the other hand, sterile females were less likely to mate. Our findings encourage further research regarding the use of SIT to control D. suzukii.
