ABSTRACT - The objective of this work was to describe the sexual dimorphism and mating behavior of Lobiopa insularis for the development of pest control and management programs. The morphological characteristics for separating males and females were described with the aid of a stereomicroscope. Mating sequence was recorded over 72 hours with a digital camera. There are differences between males and females in the last abdomen segments, and males maintain a guarding position after mating. The obtained data can be used in monitoring programs to precisely identify the sex of the insects, also shedding light on the ecological features of this pest and Nitidulidae. RESUMO - O objetivo deste trabalho foi descrever o dimorfismo sexual e o comportamento de cópula de Lobiopa insularis, para o desenvolvimento de programas de controle e manejo de pragas. As características morfológicas para separação de machos e fêmeas foram descritas com auxílio de estereomicroscópio. A sequência de cópula foi registrada por 72 horas com câmera digital. Há diferenças entre machos e fêmeas nos segmentos finais do abdômen, e os machos mantêm posição de guarda após a cópula. Os dados obtidos podem ser usados em programa de monitoramento para uma identificação precisa do sexo do inseto, além de lançarem luz sobre os traços ecológicos desta praga e de Nitidulidae. |

Herbivory is known to increase the emission of volatiles, which attract natural enemies to herbivore-damaged plants in laboratory and agricultural systems. We report on signalling through volatiles induced by Euschistus heros (F.) (Heteroptera: Pentatomidae) in two legumes that influence the attraction and retention of the egg parasitoid Telenomus podisi (Ashmead) (Hymenoptera: Scelionidae). Air-borne extracts obtained from two host plants of E. heros, soybean, Glycine max, and pigeon pea, Cajanus cajan (Leguminosae), produce a different blend of emitted volatiles when attacked by adult males or females and nymphs of the pest species, compared with the undamaged plants. The same results were obtained when the plants were treated with extracted saliva of E. heros which had been mechanically introduced into the plants. This indicates that some substance in the saliva contributed to the release of the volatiles. Bioassays in a Y-tube olfactometer with female T. podisi and treated plants confirmed the significant preference of the egg parasitoid for plants attacked by either males, females, or fourth instar nymphs of the pest species. On the other hand, volatile extracts obtained from soybean subjected to the velvetbean caterpillar, Anticarsia gemmatalis, a non-host species for T. podisi, showed a different blend of volatiles compared to those obtained from plants subjected to E. heros. Additionally, the volatiles obtained from this planthost complex were not attractive to T. podisi. These results indicate that E. heros causes an increase in the emission of specific plant volatiles, and that the induction is possibly caused by an elicitor present in the pest saliva. The possibility that these plant volatiles play an important role in the attraction and retention of the egg parasitoid T. podisi is discussed.
