Neural processing of chemosensory information from the locust ovipositor
… (basiconic sensilla) located on the ovipositor and genital segments of the locust serve to control the chemical features of the substrate before and during oviposition. They occur dispersed and also crowded in fields between mechanosensory exteroceptors sensitive to touch or wind …

Morphology of Acercaria: investigations of the ovipositor and internal anatomy
… morphology with a treatment focusing on the ovipositor. By comparing ovipositors among representatives of Hemiptera's infraorders and describing their character states using a common lexicon for homologous structures, it became apparent that ""laciniate"" (plant-piercing) ovipositors vary in …

Aspects of the morphology of the ovipositor of Hylotrupes bajulus (L.) (Coleoptera: cerambycidae)
… years. The female H. bajulus has an elongated ovipositor comprised of the modified abdominal segments 8 and 9, intersegmental membrane 8/9, and pair of distal gonostyli. When not in use, the ovipositor is retracted within abdominal segment 7. The 8th abdominal segment forms the proximal end of …

Role of labellar and ovipositor taste sensilla of Drosophila suzukii in host recognition: a morpho-functional and behavioural approach.
… to infest healthy fruits because of its serrated ovipositor used to pierce the skin of fruits and lay eggs in them. This saw-like ovipositor represents one key adaptation, but other traits, such as fruit recognition mediated by the olfactory and/or gustatory systems, are also implicated. …

Structure, distribution and innervation of sensilla on the ovipositor of the spruce budworm Choristoneura fumiferana, and electrophysiological reponses from type II sensilla
… used to perform this first investigation of the ovipositor of Choristoneura fumiferana. The female spruce budworm has four types of trichoid sensilla on its ovipositor. A unique and rare type of sensillum is described. This Type II sensillum is multiporous and also has a single pore at the tip. …

Fine structure of the ovipositor and studies of feeding and oviposition site selection by the serpentine leafminer, Liriomyza trifolii (Burgess) (Diptera: Agromyzidae)
Ovipositors of female leafminers were examined microscopically to locate and describe types of sensory receptors present. Two basic types were found: trichoid sensilla and basiconic sensilla. These receptors are believed to function as mechano- and chemoreceptors to evaluate the suitability of a …

Integrating Molecular, Ecological and Morphological Data to Explore the Biodiversity of Microgastrine Parasitoid Wasps
… wasps. The morphology of the insect ovipositor apparatus is often functionally constrained for females and strongly correlated with and convergent on feeding behavior of its host caterpillars. Discriminant analysis found that male genitalia shape was also correlated with the …

Natural regulation of coprophagous Diptera in Virginia
… is normally accomplished by penetration of the ovipositor throush the posterior spiracles of the host, The ovipositor of one female was observed to penetrate the anterior spiracle of a face fly pupa. Muscidifurax ravtor is not limited to the spiracles for penetration of house fly pupae. …

Morphological Variation and Community Science in Orthoptera
… key morphological traits, such as body size and ovipositor length, and we directly compare phenotype with genotype for a subset of crickets demonstrating nuclear genetic introgression, phenotypic intermediacy of hybrids, and essentially unidirectional mitochondrial introgression. We discuss how …

Spotted Wing Drosophila (Drosophila suzukii) in Arkansas: Winter Morphs, Wild Hosts, and Fungal Control
… native Drosophila, SWD females have a serrated ovipositor that allows them to attack ripening fruit. Since its introduction, it is unclear how and where they overwinter in Arkansas, what local hosts they utilize and what potential alternative tactics can be used to combat this pest. In states …

Oviposition behaviour of Neltumius arizonensis Schaeffer (Coleoptera: Bruchidae) : a biological control agent of Prosopis spp. in South Africa
… remaining stationary, and scraping of the ovipositor across the surface prior to egg deposition, occupied significantly more time on pods than other activities. Pod type did not affect the total time females spent on pods, nor the frequency of visits to pods. The availability of clean seeds …

Spotted-wing Drosophila: Investigating the Efficacy of Innovative and Alternative Management Techniques
… SWD use a heavily sclerotized and serrated ovipositor to deposit eggs in ripening and ripe fruit. Larvae then emerge and develop within the flesh which results in unmarketable fruit at harvest. Consequently, there is a zero-tolerance threshold for larvae in fresh fruit. Current management …

The complex foraging strategy of the specialised gallfly Urophora cardui (Diptera: Tephritidae) for host plants (Cirsium arvense, Asteraceae)
… by conspecifics also. On the tip of the females’ ovipositor there is a receptor field with several morphological different receptor types. Mainly they seem to have mechanoreceptive as well as chemosensory functions. These receptors enable the females to measure and analyse the inner structure of …

Plant-insect interactions between female dogwood borer and apple
… and evening. Casting flight, probing with the ovipositor, and oviposition were the most frequent behaviors observed, but the duration of those behaviors was relatively short compared with the much lengthier periods of resting behavior that typically occurred within the canopy. Data from a …
