Abstract

Predation by Podisus maculiventris (Say) (Hemiptera: Pentatomidae) was evaluated with Erionota thrax (L.) (Lepidoptera: Hesperidae), Pericyma cruegeri (Butler) (Lepidoptera: Noctuidae), Pareuchaetes pseudoinsulata Rego Barros (Lepidoptera: Arctiidae), Papilio polytes (L.) (Lepidoptera: Papilionidae) and Eudocima phalonia (L.) comb. nov. (Lepidoptera: Noctuidae). Both free-choice and no-choice experiments indicated that the P. maculiventris attacked and consumed all the larvae of the 5 species included in the tests. Although the larvae died at different intervals, most of them were dead within 24-120 h of the introduction of the predatory species. Since the P. maculiventris is polyphagous in nature and the present findings indicate that these predators will feed on the introduced biocontrol moth, P. pseudoinsulata, it is recommended not to take the predators out of the quarantine laboratory for the field release on Guam. Additionally, P. maculiventris will feed on some native species as they become available.

Se evaluó la depredación por Podiscus maculiventris (Say) (Hemiptera: Pentatomidae) utilizando Erionota thrax (L.) (Lepidoptera: Hesperidae), Pericyma cruegeri (Butler) (Lepidoptera: Noctuidae), Pareuchaetes pseudoinsulata Rego Barros (Lepidoptera: Arctiidae), Papilio polytes (L.) (Lepidoptera: Papilionidae) y Eudocima phalonia (L.) comb. nov. (Lepidoptera: Noctuidae). Los resultados de ambos experimentos de opción-libre y de no opción indicó que P. maculiventris ataca y consume todas las larvas de las cinco especies incluidas en las pruebas. Aunque las larvas murieron en diferentes intervalos, la mayoria de ellos murió entre las 24 y 120 hors después de la introdución de la especie depredadora. Debido a que P. maculiventris es polífago en la naturaleza y los resultados actuales indican que estos depredadores se alimentan de P. pseudoinsulata, una polilla introducida como un agente de control biológico, se recomienda que no se dejan salir estos depredadores del laboratorio de cuarantena para liberarlos en el campo. Por otra parte, P. maculiventris se pueden alimentar de algunas especies nativas en cuanto estén disponsibles
