Edward B. Mondor,* Michelle N. Tremblay and Richard L. Lindroth Department of Entomology, University of Wisconsin, Madison, WI 53706, USA *Correspondence: E-mail: [email protected] Abstract Organisms often exhibit transgenerational phenotypic changes in response to an increased risk of parasitism or predation. Shifts in global atmospheric composition could modify these phenotypic effec...

It has been hypothesized that the success of a biological control introduction is, in part, dependent on the ability of the control agent to become established in its new environment or to its new population of hosts through local adaptation. Despite this, few studies have investigated the influence of the recent coevolutionary history of pest species and natural enemies on the efficacy of biol...

in this research, host stage preference of parasitoid wasp, aphidius matricariae haliday in choice and no-choice tests and functional response of the parasitoid were investigated on common wheat aphid, schizaphis graminum rondani on the alvand cultivar in laboratory conditions at 20, 25 and 30 °c, rh 70 ±10 % and a photoperiod of 16 h l : 8 h d. the maximum mean parasitisms in choice and no-cho...

in this research, the effect of entomopathogenic fungus, beauveria bassiana (ascomycota, hypocreales), on functional response (in laboratory) and reproduction (in microcosm) of parasitoid wasp, aphidius matricariae haliday (hym.: braconidae) on its host, myzus persicae (sulzer) (hem.: aphididae) was investigated. illustrating number of mummified aphids versus initial density of green peach aphi...
