Fertility table and rate of population growth of the predator Supputius cincticeps (Heteroptera: Pentatomidae) on one plant of Eucalyptus cloeziana in the field

Abstract

The reproductive potential and population growth (r m and λ) of the predator Supputius cincticeps (Heteroptera: Pentatomidae) were evaluated using a life and fertility table. S. cincticeps was reared on one plant of Eucalyptus cloeziana in the field and fed with Tenebrio molitor (Coleoptera: Tenebrionidae) pupae. Females of this predator had a net reproductive rate (R o ) of 21.02 females/female; an intrinsic rate of population increase (r m ) of 0.041 and finite rate of increase (λ) of 1.042. This resulted in population growth of S. cincticeps in the eucalyptus plant with a doubling time of 17.01 days. This natural enemy can be reared under field conditions with alternative prey for use in biological control. Such individuals of S. cinticeps will be better adapted to field conditions when they are liberated.

A dieta alimentar da presa Tenebrio molitor (Coleoptera: Tenebrionidae) pode afetar o desenvolvimento do predador Podisus nigrispinus (Heteroptera: Pentatomidae)?

“…Além da criação de P. nigrispinus, larvas, pupas e adultos de T. molitor podem ser utilizados na criação de outros predadores (Grundy et al, 2000;Zanuncio et al, 2004), parasitoides (Zanuncio et al, 2008;Andrade et al, 2010), pássaros (Martinson;Flaspohler, 2003), morcegos (Mccartney et al, 2007), aranhas (Japyassú;Jotta, 2005), peixes (Ng et al, 2001) e lagartos (Font; Molina-Borja, 2004) e na degradação de resíduos de criatórios de aves (Fischer et al, 2004).…”

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

“…On the other hand, the number of eggs per female of the N. roseipennis predator was lower with caterpillars of P. includens in insect resistant PI229358 soybean cultivar (Pfannenstiel & Yeargan, 1998) (Zanuncio et al, 2000) and of P. nigrispinus (Lemos et al, 2001;Freitas et al, 2006), because predators of the stink bug feed on plants to increase their capacity of postures in habitats with lower prey availability (Coll & Guershon, 2002;Zanuncio et al, 2004;Lemos et al, 2009b).…”

Phytophagy of the predator Podisus nigrispinus (Dallas, 1851) (Hemiptera: Pentatomidae) fed on prey and Brassicaceae

“…In the field, plant-derived substances can be an alternative or complementing the diet of predatory bugs (Crum et al, 1998), allowing them to maintain their longevity (Valicente and O'Neil, 1995;Zanuncio et al, 2004). The use of plants as dietary supplement may or may not lead to a better establishment of predatory bug populations, depending on the composition of the agroecosystems .…”

“…Alternative preys and artificial diets are used to mass rearing this predator P. nigrispinus (Fernandes et al, 1996;Zanuncio et al, 1996a;Saavedra et al, 1997;Zanuncio et al, 1996b), in view of the difficulties of using natural prey in the laboratory.…”
