Acceptance of International Students: Host and Sojourner Characteristics
International Journal of Group Tensions, 1997This study was designed to investigate how both characteristics of the sojourner and of the host affect how American students regard and treat international students in the United States. Undergraduates (N=198) evaluated college admission applications. All applicant information was held constant except for gender, race, and nationality.

The influence of previous host age on current host acceptance in Trichogramma
Entomologia Experimentalis et Applicata, 1997Abstract Trichogramma principium Sug. & Sor. females were sequentially offered two portions of the grain moth (Sitotroga cerealella Oliv.) eggs, either young (1‐day old) or old (eggs that had developed 6 days at a temperature of 20 °C). The probability of host acceptance depended not only on current host age, but also on the age of the previously ...

The host-feeding parasitoid Ooencyrtus nezarae Ishii accepted 0–7 d eggs of Riptortus clavatus Thunberg. Host acceptance behavior was divided into four different behavioral phases: examining, drilling, host feeding, and ovipositing. The amount of feeding and number of eggs laid per host decreased with increasing host age.

Telenomus remus Nixon is an egg parasitoid used against fall armyworm, Spodoptera frugiperda (J. E. Smith), in various countries of the Americas. The feasibility of rearing T. remus at lower cost and greater efficiency on a novel host, Ephestia kuehniella Zeller, was addressed in a two-part study. The first part of the study compared acceptance of eggs

Host-acceptance behaviour in an herbivorous fly, Delia antiqua
Journal of Insect Physiology, 1988Abstract Host-plant recognition in the onion fly, Delia antiqua (Meigen), was investigated by presenting reproductively mature females with surrogate plants and manipulating single surrogate features against a backdrop of unchanged stimuli. Colour, shape, and size of surrogate foliage all influenced oviposition.

Host-Acceptance Behavior of Dinocampus coccinellae (Hymenoptera: Braconidae)
Annals of the Entomological Society of America, 1992Dinocampus coccinellae (Schrank) spent >80% of a 300-s observation period in host-handling activities (orienting toward, pursuing, and attacking hosts) when exposed to individual adult Coleomegilla maculata (DeGeer) or Coccinella septempunctata (L.). When D.

Host acceptance and oviposition byPodagrion meridionale Masi
Entomophaga, 1969The egg capsules ofSphodromantis viridisForsk. are composed of an inner, hard core and an outer spongy cover. The female ofPodagrion meridionaleMasi oviposits readily in mature or old egg capsules. Oviposition lasts more than half an hour and is preceeded by lengthy probing. The adult parasites chew out emergence holes in the capsule.

Evolution of host acceptance and its reversibility in a seed beetle
Ecological Entomology, 20161. Adapting to a low‐quality plant may require modification of an insect's digestive physiology, oviposition behaviour, or other host‐use traits. If colonising a marginal host entails a cost, a decay in adaptation would be expected after selection is relaxed, i.e. if populations on a novel host are reverted to their high‐quality ancestral host.

Dynamic information and host acceptance by a tephritid fruit fly
Ecological Entomology, 1989Abstract. 1. Female apple maggot (Rhagoletis pomonella Walsh) flies held in field cages usually oviposited in an unparasitized (non‐pheromone marked) fruit when it was encountered. 2.
