BACKGROUND The honey bee (Apis mellifera) is a highly diverse species commonly used for honey production and pollination services. The oviposition of the honey bee queen affects the development and overall performance of the colony. To investigate the ovary activation and oviposition processes on a molecular level, a genome-wide analysis of lncRNAs, miRNAs and mRNA expression in the ovaries of ...

1. Plant defence of Viburnum shrubs against oviposition by its specialist herbivore, the viburnum leaf beetle [VLB Pyrrhalta viburni(Paykull)], involves an egg-crushing wound response in twigs. Although the response is variable among Viburnum species, it can have a strong impact on egg survivorship. Beetles typically aggregate egg masses with conspecifics along infested twigs, forming clusters ...

The waste artificial larval rearing media of New World screwworms, Cochliomyia hominivorax (Coquerel) were evaluated to determine their effectiveness as oviposition attractants. Various concentrations of waste larval media resulting from rearing screwworm larvae in gel and cellulose fiber-based artificial diets tested over a 4-wk period attracted varying number of gravid screwworm flies to ovip...

The oviposition preference and larval performance of females of Ceratitis capitata (Wiedemann) were examined. Wild or laboratory-reared females were tested for oviposition preference in relation to papaya fruit in different stages of ripeness, as well as to two different fruits: papaya and apple. The results demonstrated that both laboratory-reared and wild females preferred ripe papaya fruit c...

biological reactions of the two-spotted spider mite (tss), tetranychus urticae, were studied on nine cultivars of tomatoes. the spider mites were reared on leaf discs, taken from fruiting stages of the host plants. the effects of feeding on some tomato cultivars, namely: long shelf life, meran (greenhouse cultivars), redclude, western red, imperial, yazd, mazandaran, west azarbaijan and khorasa...

Location and selection of an oviposition site is an essential part of the life history of all mosquito species. The remarkable number of oviposition be­ haviors range from the common, e.g. deposition of eggs on or near the water surface, to the unusual, e.g. egg brooding by adult females (73, 74). The initiation of an ovipositional flight is linked with environmental factors, especially rainfal...

toxicity and oviposition deterrent activities of ethereal extracts of exocarp and kernel of ginkgo biloba seed were evaluated on various life stages of two spotted spider mite tetranychus urticae. petroleum ether was used for extraction. bioassay was conducted using three replicates for testing five concentrations 35, 45, 60, 75 and 100 g/l of pure extracts. lc50 was measured by pri-probit soft...
