Ovarian development, fertility and fecundity inPodisus maculiventrisSay (Heteroptera:Pentatomidae): an analysis of the impact of nymphal, adult, male and female nutritional source on reproduction

Reproduction and longevity of Supputius cincticeps (Het.: Pentatomidae) fed with larvae of Zophobas confusa, Tenebrio molitor (Col.: Tenebrionidae) or Musca domestica (Dip.: Muscidae)

“…This agrees with lower weight of the ovaries and quantity of fat bodies of P. nigrispinus females fed with M. domestica larvae (Lemos et al 2003). Therefore, nymphs of predatory Pentatomidae fed with food of lower nutritional value will produce adults with reduced fertility (Wittmeyer et al 2001). This shows a direct effect of the diet on total number of individuals produced by predatory Pentatomidae in the next generations.…”

“…Despite of the similarity that was found among the pre-and post-oviposition periods and the number of eggs/egg mass, with different alternative preys, the oviposition period, number of egg masses and total number of eggs per female of S. cincticeps had significantly lower values when reared on M. domestica larvae than on Z. confusa or T. molitor larvae. These results showed direct relationship between body weight and fecundity of females of this predator and indirectly a possible better nutritional quality of larvae of both Tenebrionidae (Mohaghegh et al 1999, Wittmeyer et al 2001. Besides, the number of S. cincticeps nymphs hatched was ca.…”

“…This shows a direct effect of the diet on total number of individuals produced by predatory Pentatomidae in the next generations. However, this negative impact tends to be overcomed or reduced when these natural enemies feed on better quality or different prey types (Wittmeyer et al 2001. Longevity of S. cincticeps females was ca.…”

Survival and Reproduction of Podisus nigrispinus (Heteroptera: Pentatomidae): Effects of Prey Scarcity and Plant Feeding

“…This seems to be intrinsic to the species studied and it is not affected by adverse conditions including prey shortage, because oviposition would occur only after feeding on sufficient quantity and quality of prey to form egg masses (Shapiro et al, 2000;Wittmeyer et al, 2001). Similar egg viability between treatments shows that even with a cumulative effect of undernourishment or malnutrition, P. nigrispinus females did not reduce the egg viability if prey is found after 15 days of prey shortage.…”

Podisus nigrispinus (Heteroptera: Pentatomidae) and IAC-24 Soybean Cultivar Are Compatible

“…Poorly nutritious prey, such as larvae of Musca domestica L., 1758 (Diptera: Muscidae) and caterpillars of Trichoplusia ni Hübner, 1803 (Lepidoptera: Noctuidae) reduced the growth and the fertility and increased the development and mortality of predators (Wittmeyer et al, 2001;Zanuncio et al, 2001), but this effect was reduced for Podisus nigrispinus Dallas, 1851 (Heteroptera: Pentatomidae) when branches of Eucalyptus cloeziana F. Muell or Psidium guajava L. (Myrtaceae) were added to the diet of Tenebrio molitor L., 1758 (Coleoptera: Tenebrionidae) pupae (Lemos et al, 2009a). However, the mortality rate of Geocoris punctipes Say, 1832 (Hemiptera: Lygaeidae) was higher with caterpillars of A. gemmatalis in insect resistant soybean cultivar (Rogers & Sullivan, 1986) and Nabis roseipennis Reuter, 1872 (Hemiptera: Nabidae) had slow development and reduced fertility with caterpillars of Pseudoplusia includens Walker, 1857 (Lepidoptera: Noctuidae) in insect resistant soybean cultivar (Pfannenstiel & Yeargan, 1998), indicating that such crops may have indirect impact on polyphagous insects.…”
