Predation rate of Spodoptera frugiperda (Lepidoptera: Noctuidae) larvae with and without defense by Podisus nigrispinus (Heteroptera: Pentatomidae) BABT
Zanuncio,José Cola; Silva,Carlos Alberto Domingues da; Lima,Eraldo Rodrigues de; Pereira,Fabrício Fagundes; Ramalho,Francisco de Souza; Serrão,José Eduardo.
The effect of the defense of the prey Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) on predation rates of Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) females was studied. P. nigrispinus preyed 1.0, 1.4, 1.2, 3.8 and 3.0 and 0.4, 0.8, 1.6, 2.8 and 3.2 third instars of S. frugiperda larvae with and without defense, respectively, with the densities of one, two, four, six and eight larvae. The attack rate and the manipulation time were, respectively, 0.67 ± 0.39-h and 6.72 ± 2.88 h for P. nigrispinus females fed with larvae with defense and 2.51 ± 0.16-h and 0.51 ± 0.77 h for those without defense. The functional response of the predator P. nigrispinus varies with the defense and the density of the prey S. frugiperda, with larger...

Effect of ivermectin on the life cycle and larval fat body of Culex quinquefasciatus BABT
Alves,Stenio Nunes; Serrão,José Eduardo; Mocelin,Giovani; Melo,Alan Lane de.
The present work investigated the behavior, survival rate and lethal effect of 1.5 ppb ivermectin on Culex quinquefasciatus larvae, based on morphological and biological parameters, and possible alterations of their fat body. Changes in the number of eggs/egg mass and length of the larval stage were investigated. For this experiment, 600 larvae of 3rd and 4th instars of the mosquito were tested. The laid eggs were separated and the hatched larvae were counted. Some larvae submitted to 1.5 ppb ivermectin solution were used to prepare samples for histological study. Results obtained showed that ivermectin in a concentration of 1.5 ppb caused paralysis to the larvae with a mortality rate of 73.38%, mobilization of substances stored in the fat body and...

Development and survival of nymphs of Podisus nigrispinus (Heteroptera: Pentatomidae) fed with caterpillars of Chlosyne lacinia saundersii (Lepidoptera: Nymphalidae) BABT
Silva,Carlos Alberto Domingues da; Zanuncio,Teresinha Vinha; Cunha,Bruno Gomes; Castro,Ancidériton Antonio de; Canevari,Glauco da Cruz; Serrão,José Eduardo; Zanuncio,José Cola.
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.

No direct effects of resistant soybean cultiva IAC-24 on Podisus nigrispinus (Heteroptera: Pentatomidae) Chilean J. Agric. Res.
Cola Zanuncio,José; Azevedo de Freitas,Fernando; de Souza Tavares,Wagner; Lourenção,André Luiz; Vinha Zanuncio,Teresinha; Serrão,José Eduardo.
The parameters of survival, development and reproduction of Podisus nigrispinus Dallas, 1851 (Heteroptera: Pentatomidae) may be affected by feeding on soybean (Glycine max L. Merr.; Fabaceae) cultivars. The direct effect was evaluated of the insect-resistant soybean 'IAC-24' (insect-susceptible soybean 'UFVS-2006' + pupae of Tenebrio molitor L., 1758 Coleoptera: Tenebrionidae versus 'IAC-24' plants + pupae of T. molitor) in the nymph and adult stages of the predator P. nigrispinus. The duration of the nymph stage was similar between treatments, but 'IAC-24' reduced the duration of the IV instar of this predator. The survival of P. nigrispinus was similar between treatments in the instars I, II, IV and V and in the nymph stage, but the survival of the III...
