Male Preference for Large Females and Female Reproductive Condition in the Japanese Beetle, Popillia japonica Newman (Coleoptera: Scarabaeidae)

“…They appeared to call females pheromonally, inflating their abdominal pleura and everting a tri-lobed rectal ampulla. Fourteen video recordings confirmed the general descriptions of Quilici et al (2002). The male responded to an approaching female by performing continuous wing vibration.…”

“…In C. capitata, males lure females to leks with pheromones, and court them face-to-face at close range, apparently utilizing visual and chemical stimuli, as well as tactile stimulation with their antennal aristae (Eberhard, 2000;Briceño and Eberhard, 2002b). Quilici et al (2002) gave brief descriptions of some aspects of courtship in the Mascarene fruit fly, C. catoirii Guérin-Mèneville, and the Natal fruit fly C. rosa Karsch. In this paper we present further details of the sexual behavior of three species of Ceratitidini that damage crops on Reunion Island: two polyphagous species (C. catoirii and C. rosa), and the stenophagous Tomato fruit fly, Neoceratitis cyanescens (Bezzi), which attacks wild and cultivated Solanaceae.…”

Comparative Allometry and Sexual Behavior of Four Fruit Fly Species in the Tribe Ceratitidini (Diptera: Tephritidae)

“…Nine video recordings of courtships in which the male eventually mounted the female were analyzed. As noted by Quilici et al (2002), male behavior resembled that of male C. capitata, and included continuous wing vibration while the male faced the female early in courtship, and intermittent wing buzzing later after the female approached closer. The flies approached closely, to within about 0.25 body lengths, before the male jumped onto the female.…”

Molecular evaluation of nominal species in the Ceratitis fasciventris, C. anonae, C. rosa complex (Diptera: Tephritidae)

“…The highly polyphagous species of the FAR complex show largely overlapping distributional areas and host spectra . However, the elaborate species-specific mating behaviour of fruit flies (Quilici et al, 2002;Pike et al, 2003) is supposed to prevent inter-specific hybridisation under field conditions. Interspecific hybrids of the three FAR morphospecies have hitherto not been reported from natural populations.…”
