Environmental Entomology, 1979
Gelis tenellus is among the top 3 most abundant hyperparasites of Apanteles melanoscelus (Ratzburg). Inexperienced females do not discriminate between parasitized and unparasitized host coccons. Mock cocoons treated with a hexane extract of the host cocoons were probed more than untreated mock cocoons suggesting the existence of a kairomone that ...

Journal of Insect Physiology, 2012
The probing and larviposition behaviour of the bird cherry-oat aphid, Rhopalosiphum padi on summer and winter host plants were investigated using electrical penetration graph (EPG) coupled with simultaneous video recording. In this way the precise probing history prior to parturition can be monitored and the location of possible reproductive stimulants

Willingness to Pay and Accept for Hosting Olympic Games in Germany
SSRN Electronic Journal, 2016This empirical study investigates whether and how much individuals are willing to pay for hosting Olympic Games in Germany. Moreover, it is examined for the first time what individuals are willing to accept to host Olympic Games in their own country if they do not like that. Furthermore, this study identifies determinants that influence the willingness

The Importance of Stimulus Patterns for Host-Plant Recognition and Acceptance
1976Studies of lepidopterous larvae have indicated that at least for these plant feeding insects host-plant recognition and acceptance are based upon complex mixed olfactory and gustatory sensory information. Although a particular compound or category of compounds may dominate the chemical composition of a plant and may contribute the major sensory cue, it

Host-plant acceptance by aphids: cues initiating reproduction
2010The host-plant acceptance behaviour of aphids was examined, in two aphid species, the bird cherry-oat aphid, Rhopalosiphum padi and the pea aphid, Acyrthosiphum pisum, to elucidate the recognition factors used to assess plant suitability for parthenogenetic reproduction.

Laboratory investigations on the role of host instar in host location and acceptance of naïve females of Psyttalia concolor (Szépligeti) (Hymenoptera Braconidae) were conducted. Ceratitis capitata (Wiedemann) (Diptera Tephritidae) larvae were used as hosts.
