Floral mimicry of decaying plant or animal material has evolved in many lineages and exploits, for the purpose pollination, insects seeking oviposition sites. Existing studies suggest that volatile signals play a particularly important role these systems. Here, we present first large-scale phylogenetically informed study patterns evolution emissions plants mimic insect Multivariate analyses showed strong convergent evolution, represented by distinct clusters chemical phenotype space carrion,...
The oriental fruit fly Bactrocera dorsalis is one of the most destructive agricultural pests worldwide, with highly debated species delimitation, origin, and global spread routes.Our study intended to (i) resolve taxonomic uncertainties between B. carambolae, (ii) reveal population structure invasion routes across Asia, Africa, Oceania, (iii) identify genomic regions that are responsible for thermal adaptation dorsalis.Based on a high-quality chromosome-level reference genome assembly, we...
The volatile compounds emitted from uninfested apple seedlings, cv. Royal Gala, and seedlings infested with generalist herbivore Epiphyas postvittana larvae were sampled using headspace collection analyzed by gas chromatography-mass spectrometry. Nine additional only detected in [including benzyl alcohol, (E)-β-ocimene, cyanide, indole, (E)-nerolidol, four unidentified compounds]. Infested produced larger amounts of (Z)-3-hexenyl acetate, linalool, 4,8-dimethyl-1,3(E),7-nonatriene, methyl...
Plant chemical signals are important olfactory cues for the survival and reproduction of phytophagous insects. The diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidae) is a Brassica spp. (Brassicales: Brassicaceae) specialist pest, with most its life events occurring on hosts. We conducted scanning electron microscopy study morphology distribution antennal sensilla male female P. xylostella. Seven morphological types were identified in antennae xylostella: 3 trichodea (Tr I,...
Abstract Males of the oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), are strongly attracted to, and feed voraciously on, methyl eugenol (ME) use metabolites this chemical to synthesize their sex pheromone. Previously, Wong et al. (1989 ) proposed that B . males were ME even before attaining sexual maturity. However, interpretation is possibly confounded by fact that, in monitoring age‐related mating readiness, presented with equal‐aged females. As a result, if...
Abstract The Artocarpus fruit fly, Bactrocera umbrosa (Fabricius) (Diptera: Tephritidae), is an oligophagous pest infesting Moraceae fruits, including jackfruit ( heterophyllus Lamarck), a commodity of high value in Malaysia. scarcity fundamental biological, physiological and ecological information on this pest, particularly relation to behavioural response phytochemical lures, which are instrumental the success many area-wide fly control management programmes, underpins need for studies...
Abstract Bactrocera carambolae Drew & Hancock and B. papayae (Diptera: Tephritidae), two closely related sibling species in the dorsalis (Hendel) complex were shown to have different rates of sexual maturity. The response males methyl eugenol was observed begin 10 days after emergence increased with age. attractancy peaked at 28 above. also found require a higher dosage (1 mg) for optimal response. These results are contrast those reported previously. correspond age when first mating...
The effects of substerilizing doses gamma radiation on the longevity and level inherited sterility in Australian moth Teia anartoides Walker were determined. Six day-old male pupae treated with 0, 100, 160 Gy by using a 1.25 MeV Cobalt60 irradiation source. Laboratory studies showed that had little impact adult moths P1, F1, F2 generations. Inherited deleterious resulting from observed progeny F1 Outcrosses between substerile parental males or their highly sterile to wild-type females did...
The unique genetic phenomena responsible for inherited F1 sterility in Lepidoptera and some other arthropods provide advantages the use of a sterile insect technique (SIT) program. Lepidopteran females generally can be completely sterilized at dose radiation that only partially sterilizes males same species. When these mate with fertile females, many radiation-induced deleterious effects are by generation. At appropriate radiation, egg hatch mated irradiated is reduced resulting (F1)...
In this study we identified a number of moth (Lepidoptera) species that are potential targets for the sterile insect technique (SIT), and assessed feasibility using stable isotope signatures as markers to distinguish mass-reared from wild species. Large natural differences in isotopic commercially available sugars render them novel insects. Sugar beet (Beta vulgaris L.; Caryophyllales: Amaranthaceae), C3 plant, has signature (a measure ratio isotopes 13C:12C) around -27‰ relative Vienna Pee...
Abstract Fuller's rose weevil (FRW; Pantomorus cervinus ) (Coleoptera: Curculionidae), a polyphagous pest of citrus and other horticultural plants, was studied in laboratory assays designed to identify potential semiochemicals from host plants that might be exploited for management. Using still‐air bioassays, weevils were found most attracted fresh whole lemon leaves compared with cut and/or dried leaves. White clover, an understorey plant kiwifruit orchards, also attractive the dual‐choice...
