Effects of two different plants, potato, Solanum. tuberosurn L., and toma to, Lycopersicon esculentum Mill., arrd fceding regimes on selected life history characteristics ofthe predator Podisus maculiventris (Say) were investigated. Prey were third instar Colorado potato beetle, Leptinotarsa decemlineata (Say). Without access to prey, survivo rsh ip was initially higher for P. maculiuentris provided either potato or tomato plants than for predators provided only water. However, no major difference in survivorship was detected after the 35th day of life. Predators provided only plants lived up to 50 days, and predators provided only water lived up to 60 days. Predators provided either plants 01' water lost weight initially but then maintained a low weight throughout the remainder of their lives. In contrast, P. maculiventris having no access to plants or water lost weight continually until death. When feeding on relatively few L. decemlineata, P. maculiventris maintained longevity but decreased reproduction. As the time between feedings ofprey to predators increased, P. maculiventris laid fewer eggs, had lower body weights, and laid eggs later in Iife than those predators feeding on prey more frequently. These results support the concept of a trade-off between longevity and reproduction when P. maculiventris feeds on relatively few prey, This trade-off is not affected by the host plant upon which prey were reared. A tradeoff between longevity and reproduction is consistent with previous studies with P. maculiventris and may help to explain how this predator and others like it can maintain populations in fields where prey are not readily available.
