Rice Stink Bug

Biological control of Oebalus insularis eggs is considered an important strategy in the control of this rice “stink bug”. Effects of essential oils (EOs) from Piper jacquemontianum Kunth and Piper marginatum Jacq. (Piperaceae) on the viability of parasitized and unparasitized eggs by Telenomus podisi, in concentrations of 0.5 to 2.0%, were evaluated. EOs from both species at a concentration of 2% affected the development of embryons of O. insularis as well as of T. podisi after 24 and 48h of their administration. In both species, P. jacquemontanium and P. marginatum LC50, 24 h before the application of treatments on eggs of O. insularis was 3.835 y 3.037, respectively. LC50 after 48 h of treatment with EOs showed contrasting results which varied from 2.207 and 1.811. for P. jacquemontianum and P. marginatum, respectively. LC50 calculated before 24 h in parasitized eggs of O. insularis by T. podisi, was 3.037 and 2.171 for P. jacquemontianum y P. marginatum, respectively, while after 48h of treatment it was 1.166 y 1.935, respectively. Absorption of the EO components by the unparasitized and parasitized eggs of O. insularis by T. podisi was higher after 48 h of exposition. This is due to the longer exposure time, which allows higher penetration of the EOs into the interior of insect eggs by microscopic pores and micropyle.

Biological control has been reducing the use of chemical products against insect pests, specially predatory Pentatomidae. Species of this group can present high variations in their life cycle as a result of their diet. Thus, the objective of this research was to study nymph development and reproduction of Podisus distinctus (Stäl, 1860) (Heteroptera: Pentatomidae) fed on Bombyx mori L., 1758 (Lepidoptera: Bombycidae) larvae (T1), compared to those fed on Tenebrio molitor L., 1758 (Coleoptera: Tenebrionidae) (T2) and Musca domestica L., 1758 (Diptera: Muscidae) larvae (T3) at a temperature of 25 ± 0.5ºC, relative humidity of 70 ± 2%, and photophase of 12 h. Predators fed on B. mori showed duration of the nymph phase (18.68 ± 1.02) similar to those fed on T. molitor (18.32 ± 1.49). Pre-oviposition and oviposition periods and number of egg masses, besides eggs and nymphs per female, were higher with B. mori (5.83 ± 2.02; 15.00 ± 7.40; 8.42 ± 1.84; 296.69 ± 154.75; and 228.55 ± 141.04, respectively) while longevity of males and females of P. distinctus was 25.76 ± 16.15 and 35.00 ± 16.15 days with T. molitor, and 20.57 ± 13.60 and 23.46 ± 12.35 days with B. mori, respectively.

The mecideine stink bug genus Mecidea is represented in America north of Mexico by three species: Mecidea major Sailor, Mecidea minor Ruckes, and Mecidea longula Stål. M. major and M. minor are widely distributed, occurring collectively from the Midwest to California. M. longula is known only from south Florida. The life histories of M. major and M. minor have been published including laboratory rearing from egg to adult and descriptions of the immature stages. However, no key has been developed for identification of the nymphs of these two species. Here, we present a key to the nymphs of these taxa to the species and instar levels.

The Subject

Accurate identification of parasitoids is crucial for biological control of the invasive brown marmorated stink bug, Halyomrpha halys (Stål). A recent work by Talamas et al. (2017) revised the Palearctic fauna of Trissolcus Ashmead, egg-parasitoids of stink bugs, and treated numerous species as junior synonyms of T. semistriatus (Nees von Esenbeck). In the present paper, we provide a detailed taxonomic history and treatment of T. semistriatus and the species treated as its synonyms by Talamas et al. (2017) based on examination of primary types, molecular analyses and mating experiments. Trissolcus semistriatus, T. belenus (Walker), T. colemani (Crawford), and T. manteroi (Kieffer) are here recognized as valid and a key to species is provided. The identification tools provided here will facilitate the use of Trissolcus wasps as biological control agents and as the subject of ecological studies.
