Metabolic rates of two hemipteran members of a predator-prey complex

Searching behavior and time budgets of the predator Podisus maculiventris

“…The results supported the idea that rest time was an important component of the total searching bout, rather than only 'wasted' time (Evans, 1976). Eong resting periods also have been found for the lyge'fd predator Geocoris punctipes, for which resting periods were associated with decreased water loss (Cohen, 1982), and decreased oxygen consumption and metabolic rates (Cohen, 1984(Cohen, , 1985. In addition, resting times of G. punctipes were spent in areas of the plant canopy with high humidity (Cohen, 1982) or lower temperatures (Cohen, 1985).…”

In our study, most long resting periods were spent under leaves or at the base of stems, similar to the findings for G. punctipes, so that resting by P. maculiventris may similarly serve to lower metabolic rates or prevent water losses caused by exposure to hostile microhabitats.…”

Foraging on and Consumption of Two Species of Papaya Pest Mites,Tetranychus kanzawaiandPanonychus citri(Acari: Tetranychidae), byMallada basalis(Neuroptera: Chrysopidae)

“…Most insects spend only a small part of their time feeding compared with resting and other activities (Matthews and Matthews 1978, Cohen 1985, Wiedenmann and OÕNeil 1991. Our study indicated that, during a 2-h period after an absence of prey, secondand third-instar M. basalis foraged for most of the time on all life stages of T. kanzawai and P. citri, whereas Þrst instars spent only half of the time actively foraging.…”

Feeding Fitness and Quality of Domesticated and Feral Predators: Effects of Long-Term Rearing on Artificial Diet

“…Several studies that were spawned by these questions were reviewed by Cohen and Staten (1994), and they showed that although domesticated predators were smaller and less fecund than their feral counterparts, both populations showed similar prey selection characteristics (Hagler and Cohen, 1991), similar metabolic efficiencies (Cohen, 1984(Cohen, ,1985bCohen and Urias, 1988), and similar digestive abilities when resorting to natural prey (Cohen and Byrne, 1992). Cohen and Staten (1994) and Cohen (unpublished data) demonstrated that domesticated predators fed strictly on artificial diets were able to survive field conditions and consume natural prey.…”
