Drought stress in tomatoes: changes in plant chemistry and potential nonlinear consequences for insect herbivores
G English-Loeb, MJ Stout, SS Duffey - Oikos, 1997 - JSTOR
Insect herbivores respond variably to drought-stressed plants; in some cases herbivore
performance (eg fecundity, survival) is enhanced, in others it is negatively affected. We used …

Trichomes and spider-mite webbing protect predatory mite eggs from intraguild predation
A Roda, J Nyrop, M Dicke, G English-Loeb - Oecologia, 2000 - Springer
Predaceous arthropods are frequently more abundant on plants with leaves that are pubescent
or bear domatia than on plants with glabrous leaves. We explored the hypothesis that for …
