Host Plant Selection

2003
Generally, host plant selection of leaf-cutting ants and particularly the mechanisms of selective foraging in Atta ants have been extensively studied with laboratory colonies as well as with natural colonies in the field using pick-up assays as method for both (e.g., Cherrett 1972a,b; Hubbell and Wiemer 1983; Howard 1987, 1988; Vasconcelos and Cherrett

Host selection by a kleptobiotic spider

Naturwissenschaften, 2004
Why do kleptobiotic spiders of the genus Argyrodes seem to be associated with spiders of the genus Nephila worldwide? Observations following introduction of experimental insect prey of different sizes and weights on to host webs revealed that: (1) small prey are more effectively retained on the web of Nephila clavipes than on the web of another common ...

Bacterial Virulence and Host Selection

Journal of Burn Care & Rehabilitation, 1991
A clinically lethal strain of Pseudomonas aeruginosa was tested and its growth patterns in normal plasma and in normal whole blood clotted with thrombin were compared. Two stock cultures were used; one was maintained in liquid nitrogen and one was passed from plate to plate 24 times on blood agar plates at room temperature.

Parasites, Immunology of Hosts, and Host Sexual Selection

The Journal of Parasitology, 1994
Parasite-mediated sexual selection is reviewed with special emphasis on the bird literature. Choosy females may benefit from choosing parasite-free mates if such males provide better parental care, do not transmit contagious parasites, or provide resistance genes to offspring. There is evidence in support of each of these mechanisms.

Factors affecting host selection in an insect host–parasitoid interaction

Ecological Entomology, 1997
1. Many parasitoids can develop successfully in different stages of the same host but the costs of parasitism may vary between the stages. The stage of host attacked has generally been determined when there is no choice, giving a misleading impression of host selection or preference. 2. The rate of parasitism by a

Selective attention and host‐plant specialization

Entomologia Experimentalis et Applicata, 1996
AbstractThe importance of attentional processing is summarized, and the different ways in which selective attention is maintained, explained. Examples from arthropods are highlighted. The significance of selective attentiveness for insect herbivores is discussed.

Host selection byHylemya antiqua (Meigen)

Journal of Chemical Ecology, 1978
Volatile components ofAllium cepa L, trapped in and recovered from Porapak Q, were separated by gas-liquid and thin-layer chromatography. Fractions eliciting oviposition fromHylemya antiqua (Meigen) were analyzed by combined gas chromatography-mass spectroscopy (GC-MS) and were found to contain saturated and unsaturated disulfides. Authentic samples of

Parasites, immunology of hosts, and host sexual selection.

The Journal of parasitology, 1995
Parasite-mediated sexual selection is reviewed with special emphasis on the bird literature. Choosy females may benefit from choosing parasite-free mates if such males provide better parental care, do not transmit contagious parasites, or provide resistance genes to offspring. There is evidence in support of each of these mechanisms.

Parasitism, Host Immune Function, and Sexual Selection

The Quarterly Review of Biology, 1999
Parasite-mediated sexual selection may arise as a consequence of 1) females avoiding mates with directly transmitted parasites, 2) females choosing less-parasitized males that provide parental care of superior quality, or 3) females choosing males with few parasites in order to obtain genes for parasite resistance in their offspring.
