Attack behavior of Podisus rostralis (Heteroptera: Pentatomidade) adults on caterpillars of Bombyx mori (Lepidoptera: Bombycidae) BABT
Lemos,Walkymário Paulo; Zanuncio,José Cola; Serrão,José Eduardo.
Attack behavior of the predator Podisus rostralis (Stäl) (Heteroptera: Pentatomidae) adults on fourth instar Bombyx mori L. (Lepidoptera: Bombycidae) caterpillars was studied in laboratory conditions. Ten 24 hours old adults of this predator were observed during two hours with the following attack behavior: (1) Predator: prey finding; prey observation; touching prey with antenna; attack behavior; prey paralysis; predator retreat after attack; attack cessation; successive attacks; and (2) Prey: defense. The predator P. rostralis found its prey before attacking and it approached it with slow circular movements. The attack was usually made in the posterior part of the prey to reduce defense reaction. Larger size of prey in relation to the predator resulted...

Validation of the sampling methodology for Opsiphanes invirae caterpillars on oil palm plantations in the Brazilian Amazon Ciência Rural
Oliveira,Taciane Almeida de; Lemos,Walkymário Paulo; Tinôco,Ricardo Salles; Barbosa,José Carlos; Martins,Ivan Carlos Fernandes.
ABSTRACT: This study validated the use of leaf 17 on the sampling of Opsiphanes invirae Hübner (Lepidoptera: Nymphalidae) through the quantification of caterpillar abundance on the different spirals leaves, in comparison to leaf 17, and, on the apical, intermediate and basal leaf regions. This study was performed in the state of Pará, between March-2014 and March-2015. Results confirmed that leaf 17 is the most adequate method for monitoring this defoliator pest.
