Development and survival of nymphs of Podisus nigrispinus (Heteroptera: Pentatomidae) fed with caterpillars of Chlosyne lacinia saundersii (Lepidoptera: Nymphalidae)

Abstract

The development and survival of Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) nymphs fed on larvae of Chlosyne lacinia saundersii Doubleday & Hewitson (Lepidoptera: Nymphalidae) was studied at 25 ± 1ºC, 68 ± 10% relative humidity and 12 h photo phase. P. nigrispinus developed until the adult stage when fed on C. lacinia saundersii caterpillars. However, the survival rate of P. nigrispinus during early instars allowed this predator to complement its diet with other preys and to maintain its populations in areas with the sunflower culture

Behavior, Development, and Predation of Podisus nigrispinus (Hemiptera: Pentatomidae) on Spodoptera frugiperda (Lepidoptera: Noctuidae) Fed Transgenic and Conventional Cotton Cultivars

“…For each experiment, F. nigrispinus were placed in transparent plastic pots (9.5 cm in diameter and 9.0 cm in height). The insects were maintained at a room temperature of 27 ± 2°C, 70 ± 10% RH, and a photoperiod of 12:12 (L:D) h. Water was provided using a tube fixed onto the lid of the container, with the tip turned inwards and a piece of cotton placed in the tube hole to allow supply of water by capillary action , Neves and Torres 2009, Silva et al 2009, Oliveira et al 2011, Vacari et al 2013.…”

“…Second-instar F. nigrispinus nymphs were placed individually into petri dishes with a 2.5-ml type anesthetic vial , Silva et al 2009, Oliveira et al 2011). The experiment was performed in a completely randomized design with five treatments and 30 replications.…”

Deleterious Activity of Natural Products on Postures of Spodoptera frugiperda (Lepidoptera: Noctuidae) and Diatraea saccharalis (Lepidoptera: Pyralidae)

“…The control of these species is carried out in the fi rst stages of their culture with synthetic insecticides that increase environmental risks, production costs and the dependence upon synthetic insecticides, intoxication in operators and residues in food (Zanuncio et al, 1998;Rodriguez et al, 2001;Silva et al, 2009). For these reasons, the use of less toxic products, such as neem, pyroligneous, and Asteraceae extracts is important in agricultural areas (Charleston et al, 2005;Habluetzel et al, 2007;Tavares et al, 2009).…”

Effect of the insect growth regulator diflubenzuron on the predator Podisus nigrispinus (Heteroptera: Pentatomidae)

“…They establish, survive and breed in temporary agroecosystems, have a large number of offspring per generation (Oliveira et al 2002), rapid post-embryonic development (Medeiros et al 2003a, b), adapt well to different temperatures and prey species (Torres et al 1998;Lemos et al 2003;Vivan et al 2003), are generalist feeders (Zanuncio et al 1994) and are relatively selective in their vulnerability to insecticides (Smagghe and Degheele 1995;Zanuncio et al 2003). The predatory Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) is one of the most common species of Asopinae studied in the Neotropics (De Clercq 2000), and has been reported in several countries of south and central America as an important biological control agent in different crops (Thomas 1992;Lemos et al 2005;Silva et al 2009). However, the fertility and the fecundity of P. nigrispinus can be affected when exposed to some insecticides Evangelista Júnior et al 2002).…”
