movement of sterile male bactrocera cucurbitae (diptera: tephritidae) in a hawaiian agroecosystem. | the melon fly, bactrocera cucurbitae coquillett, invaded the hawaiian island chain in 1895. in 1999, a program sponsored by the usda-ars to control melon fly and other tephritid pests in hawaii over a wide area was initiated on the islands of hawaii, maui, and oahu. to control these flies in an areawide setting, understanding how flies move within the landscape is important. to explore the movement of this fly, we examined the movement of marked, male, sterile, laboratory-reared b. cucurbitae on ... | 2005 | 16334322 |
comparative evaluation of spinosad and phloxine b as toxicants in protein baits for suppression of three fruit fly (diptera: tephritidae) species. | spinosad and phloxine b are two more environmentally friendly alternative toxicants to malathion for use in bait sprays for tephritid fruit fly suppression or eradication programs. laboratory tests were conducted to assess the relative toxicity of these two toxicants for melon fly, bactrocera cucurbitae coquillett; oriental fruit fly, bactrocera dorsalis hendel; and mediterranean fruit fly, ceratitis capitata (wiedemann) females. field tests also were conducted with all three species to compare ... | 2005 | 16156568 |
possible role of eclosion rhythm in mediating the effects of light-dark environments on pre-adult development in drosophila melanogaster. | in insects, circadian clocks have been implicated in affecting life history traits such as pre-adult development time and adult lifespan. studies on the period (per) mutants of drosophila melanogaster, and laboratory-selected lines of bactrocera cucurbitae suggested a close link between circadian clocks and development time. there is a possibility of clock genes having pleiotropic effects on clock period and pre-adult development time. in order to avoid such pleiotropic effects we have used wild ... | 2005 | 15725348 |
weathering trials of amulet cue-lure and amulet methyl eugenol "attract-and-kill" stations with male melon flies and oriental fruit flies (diptera: tephritidae) in hawaii. | amulet c-l (cue-lure) and amulet me (methyl eugenol) molded paper fiber "attract-and-kill" dispensers containing fipronil were tested under hawaiian weather conditions against bactrocera cucurbitae (coquillett) (melon fly) and bactrocera dorsalis (hendel) (oriental fruit fly), respectively. in paired tests (fresh versus weathered), c-l dispensers were effective for at least 77 d, whereas me dispensers were effective for at least 21 d. thus, c-l dispensers exceeded, whereas me dispensers did not ... | 2005 | 16334323 |
synomone or kairomone?--bulbophyllum apertum flower releases raspberry ketone to attract bactrocera fruit flies. | bulbophyllum apertum flower (orchidaceae) releases raspberry ketone (rk) in its fragrance, which attracts males of several fruit fly species belonging to the genus bactrocera. besides rk as a major component, the flower contains smaller amounts of 4-(4-hydroxylphenyl)-2-butanol, plus two minor volatile components, veratryl alcohol and vanillyl alcohol. within the flower, the lip (labellum) had the highest concentration of rk with much smaller quantities present in petals; other flower parts had ... | 2005 | 15898497 |
redressing the sex imbalance in knowledge of vector biology. | the recent development of transgenic mosquitoes that are resistant to infection by the plasmodium malarial parasite is a promising new tool in the fight against malaria. however, results of large-scale field releases of alternatively modified mosquitoes carried out during the 1970s and 1980s suggest that this approach could be difficult to implement in the field. these past attempts to control mosquito populations largely floundered as a result of our insufficient understanding of the behavioura ... | 2005 | 16701369 |

quarantine security of bananas at harvest maturity against mediterranean and oriental fruit flies (diptera: tephritidae) in hawaii. | culled bananas (dwarf 'brazilian', 'grand nain', 'valery', and 'williams') sampled from packing houses on the islands of hawaii, kauai, maui, molokai, and oahu identified specific "faults" that were at risk from oriental fruit fly, bactrocera dorsalis (hendel), infestation. faults at risk included bunches with precociously ripened bananas, or bananas with tip rot, fused fingers, or damage that compromised skin integrity to permit fruit fly oviposition into fruit flesh. no mediterranean fruit fly ... | 2001 | 11233129 |
methyl eugenol and cue-lure traps for suppression of male oriental fruit flies and melon flies (diptera: tephritidae) in hawaii: effects of lure mixtures and weathering. | methyl eugenol (4-allyl-1,2-dimethoxybenzene-carboxylate) and cue-lure [4-(p-acetoxyphenyl)-2-butanone] are highly attractive kairomone lures to oriental fruit fly, bactrocera dorsalis (hendel), and melon fly, b. cucurbitae (coquillett), respectively. plastic bucket traps were evaluated as dispensers for methyl eugenol and cue-lure for suppression of the 2 fruit flies in hawaii. methyl eugenol and cue-lure mixtures were compared with pure methyl eugenol or cue-lure over 4 seasons. b. dorsalis ca ... | 2000 | 14658515 |
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 |
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 |
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 |
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 |
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 |
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 |
