Abstract Terms describing or identifying developmental stages of horticultural crops are not used consistently, thus the meaning each term becomes ambiguous. The cause for this discrepancy is speculative; however, could be minimized if a set widely applicable definitions were available as guides in selecting appropriate terms. Lott (2) recommended terms “mature” and “ripening” their derivatives. However, his its derivatives restricted to fruit while it still attached plant, “ripe”...
In many insect species olfaction is a key sensory modality. However, examination of the chemical ecology insects has focussed up to now on living above ground. Evidence for behavioral responses cues in soil other than CO2 scarce and role played by process finding host roots below ground not yet understood. The question whether soil-dwelling beetle larvae can smell their plant been under debate, but proof as lacking that olfactory perception volatile compounds released damaged plants, known...
Abstract Background Fusarium graminearum and avenaceum are two of the most important causal agents head blight (FHB) wheat. They can produce mycotoxins that accumulate in infected wheat heads, including deoxynivalenol (DON) enniatins (ENNs), produced by F. , respectively. While role DON as a virulence factor toward is well known, ENNs has been poorly explored. Results obtained to-date indicate may confer an advantage to only on particular hosts. In this study, with use ENN-producing ENN...
Abstract In parasitic wasps, various kinds of antennal plates have been interpreted as olfactory organs due to the presence numerous pores. However, on basis ultrastructural investigations, some these multiporous were revealed being release sites exocrine glands while others postulated a gustatory function. Such sensilla, present only female antennae, show unique features, found exclusively in Platygastroidea, with differences between Scelionidae and Platygastridae. The cuticular apparatus...
Paysandisia archon (Lepidoptera: Castniidae) is a serious pest of palm trees. A comprehensive knowledge the insect olfactory system essential for development efficient semiochemical-based control methods. The sensilla are located particularly on antennae, and these can detect plant volatiles that provide important cues insects in search their host plants. To date, fine structure P. antennal studies role host-plant perception have not been investigated great detail. Using light microscopy...
The mandibles are among the most important appendages of insects’ mouthparts. Their morpho-functional organization is correlated with variation in dietary preferences. In this study, we investigated ultrastructural and metal composition two ladybird species different habits: Harmonia axyridis (an entomophagous species) Subcoccinella vigintiquatuorpunctata (a phytophagous species). was studied using Scanning Transmission Electron Microscopy, whereas Energy-Dispersive X-ray spectroscopy (EDX)....
SUMMARY We have studied the courtship behaviour of Trichopria drosophilaePerkins (Hymenoptera: Diapriidae), a pupal parasitoid common fruit fly Drosophila melanogaster Meigen (Diptera: Drosophilidae), to understand role antennae. Virgin pairs perform an intense and stereotyped antennal courtship, which leads copulation. During antennation, two male fourth antennomeres come into contact with apical female antennomeres, thus secretion produced by sex pheromone gland is spread onto receptors....
SUMMARY Volatiles emanating from ripening fruit harvested at different stages of maturity were analyzed with direct sampling techniques and a flame‐ionization‐equipped gas chromatograph. All fruits within the selected range ripened into commercially salable products. Although firmness, soluble solids, carbon dioxide production indicated nearly equivalent categories presence detectable volatiles was markedly dependent upon harvest. Additional volatile fractions detected when cut prior to...
Dryocosmus kuriphilus is a gall-inducing insect, which can cause significant damage on plants of the genus Castanea Mill., 1754. Antennae and ovipositor are main sensory organs involved in location suitable oviposition sites. Antennal sensilla host plant location, while assess suitability ovipositional bud. On both organs, diverse sensillar present. Here, distribution ultrastructural organization were investigated by scanning transmission electron microscopy. The antennae D. filiform...
ABSTRACT Neodryinus typhlocybae (Hymenoptera: Dryinidae) is a natural enemy of the planthopper Metcalfa pruinosa , which was introduced from North America into Europe and has become established in various regions as pest species. Vibrational signals play crucial role communication M . appears to be exploited by N Scanning transmission electron microscopy have shown that antennae females peculiar complex sensory structures: deep longitudinal grooves house long sensilla trichodea, termed here...
