| olfactory receptors in the melon fly dacus cucurbitae and the oriental fruit fly dacus dorsalis. | male melon flies (dacus cucurbitae) from a colony in hawaii were evaluated for limit of response to the olfactory stimulant raspberry ketone and to more than 40 related molecules. the results were compared with the limits of response of oriental fruit flies (dacus dorsalis) under identical conditions. the nature of the response of the two species to attractive compounds appeared to be identical with regard to orientation, searching, pulsating mouthparts, and compulsive feeding. however, there wa ... | 1983 | 16593321 |
| benzyl acetates as attractants for the male oriental fruit fly, dacus dorsalis, and the male melon fly, dacus cucurbitae. | fifty compounds related to benzyl acetate were evaluated quantitatively as attractants to the male oriental fruit fly (dacus dorsalis) and the male melon fly (dacus cucurbitae). thienylmethyl acetate was nearly as attractive as benzyl acetate to both species, but cyclohexylmethyl acetate was completely unattractive, emphasizing the role of the planar aromatic ring in receptor interaction. although benzyl acetate was equally attractive to both species, para substituents invariably reduced attract ... | 1986 | 16593663 |
| age-related response of male melon fliesdacus cucurbitae (diptera: tephritidae) to cue-lure. | laboratory-reared and wild adults of the melon fly,dacus cucurbitae coquillett, were tested for response to cue-lure at various ages. virgin laboratory (4, 6, 8, 10, 12, and 14 days old) and wild (10, 12, 14, 16, 18, 20, and 22 days old) flies were released into outdoor field cages and trapped from 0800 until 1600 hr. response of males to cue-lure increased with age and corresponded with sexual maturity for each strain. females of both strains were relatively nonresponsive to cue-lure. failure t ... | 1991 | 24258641 |
| accumulation ofdendrobium superbum (orchidaceae) fragrance in the rectal glands by males of the melon fly,dacus cucurbitae. | 4-(4-hydroxyphenyl)-2-butanone was characterized from flowers of the orchiddendrobium superbum as a specific attractant factor for the male melon fly,dacus cucurbitae. the male flies compulsively licked the flower surface and sequestered the compound in significant quantities in their rectal glands. the compound was detected within 6 hr after ingestion and was retained for more than six days in the rectal gland sacs. | 1993 | 24249012 |
| correlated responses to selection for developmental period in bactrocera cucurbitae (diptera: tephritidae): time of mating and daily activity rhythms. | comparisons of "time of mating" (the time copulation begins) between lines selected for short and long developmental periods have been made in the melon fly, bactrocera cucurbitae. these comparisons showed that longer development periods were associated with later initiation of mating. crosses were also made between selected lines to ascertain the genetic basis of developmental period and time of mating. comparisons of daily activity rhythms for four types of behavior (locomotion, preening, feed ... | 1997 | 9336086 |
| genetic trade-off between early fecundity and longevity in bactrocera cucurbitae (diptera: tephritidae). | the response to selection on age at reproduction was measured to test for a genetic trade-off between early fecundity and longevity in the melon fly bactrocera cucurbitae (coquillett). three replicate lines were selected for propagation by breeding from young (y-lines) and old (o-lines) adults, respectively. selection was continued for 24 and 9 generations for y- and o-lines, respectively. females from o-lines lived longer than y-line females as an indirect response to selection, indicating that ... | 1997 | 16397642 |
| genetic correlations between life-history and behavioral traits can cause reproductive isolation. | reproductive isolation may often evolve as an indirect (pleiotropic) consequence of populations adapting to different environments or habitats. for example, niches that are temporally or seasonally offset can select for organisms with different developmental characteristics. these developmental differences can inadvertently cause reproductive isolation by a variety of means including shifts in mating activity patterns. here, we show a genetic correlation between a life-history trait (development ... | 1999 | 28565193 |
