This work is the first record of Encarsia inaron (Walker, 1839) (Hymenoptera: Aphelinidae) parasitizing Bemisia tabaci (Gennadius, 1889) (Hemiptera: Aleyrodidae) on soybeans in Brazil. Morphological and molecular characterizations are provided, in addition to verification of the presence of E. inaron in areas infested by whiteflies, indicating that the wasp can potentially be used in integrated management programs. Additionally to morphological verification, the molecular analysis allowed the identification of some degree of genetic variability in the genome of the parasitoid., Este es el primer registro de Encarsia inaron (Walker, 1839) (Hymenoptera: Aphelinidae) parasitando Bemisia tabaci (Gennadius, 1889) (Hemiptera: Aleyrodidae) en soja en Brasil. Se proporcionan caracterizaciones morfológicas y moleculares, además de la verificación de la presencia de E. inaron en áreas infestadas por mosca blanca, lo que indica que la avispa puede potencialmente ser utilizada en programas de manejo integrado. Además de la verificación morfológica, el análisis molecular permitió identificar algún grado de variabilidad genética en el genoma del parasitoide.

The aim of this study was to assess the occurrence and identify the egg-parasitoid species of the cassava hornworm (Erinnyis spp.) in cassava plants (Manihot esculenta Crantz - Euphorbiaceae), facilitating their usage in the biological control as a management strategy in the Pará State. During February to December of 2016, cassava hornworm eggs were collected in the Cassava Germplasm Bank area of the Embrapa Amazônia Oriental, located at the city of Belém, State of Pará. In the laboratory, eggs were separated in viable and parasitized and were daily observed until the hatching of the caterpillars and emergence of the parasitoids. The caterpillars were reared until reaching the adult stage and the sex determined at the pupae stage. A total of 482 eggs were collected, with a higher occurrence at March, and 244 caterpillars were obtained with sex ratio of 0.52 with 191 specimens reaching adult stage. Among these adults, 95.81% were Erinnyis ello (Linnaeus) and 4.19% Erinnyis alope (Drury). A total of 1,087 parasitoids were obtained from 131 eggs and belong to four Hymenoptera families: Platygastridae (Telenomus dilophonotae Cameron), Eulophidae (Chrysonotomyia sp. aff. serjaniae), Trichogrammatidae (Trichogramma marandobai Brun, Moraes & Soares) and Encyrtidae (Ooencyrtus sp.). The Erinnyis spp. eggs were mostly parasitized by T. dilophonotae, which was classified along with T. marandobai as constant. The occurrence of these natural enemies highlights the potential for natural biological control against Erinnyis spp.

Hexacladia hilaris Burks (Hymenoptera: Encyrtidae) is a parasitoid associated to several stink bug species in Costa Rica, Porto Rico and United States. In April 2018, at the Passo Fundo (28º15’46” S / 52º24’24” O), Rio Grande do Sul state, Brazil, specimens of H. hilaris were collected from Chinavia erythrocnemis (Berg) (Heteroptera: Pentatomidae). This is the first record of this parasitoid in South America as well as its association with C. erythrocnemis.

This study reports seven species of whiteflies in the genera Aleurothrixus, Dialeurodicus, and Trialeurodes, as well as parasitism of Aleurothrixus floccosus by Signiphora sp. and Cales noacki. Three new hosts of Aleurothrixus aepim are reported. Dialeurodicus cockerellii and Trialeurodes vaporariorum are reported for the first time in Rio Grande do Sul State, Brazil., En este trabajo se registran siete especies de moscas blancas, incluyendo los géneros Aleurothrixus, Dialeurodicus y Trialeurodes, y el parasitismo de Aleurothrixus floccosus por Signiphora sp. y Cales noacki. Tres nuevos huéspedes son reportados a Aleurothrixus aepim. Dialeurodicus cockerellii y Trialeurodes vaporariorum se registran por primera vez en Rio Grande do Sul, Brasil.

The presence of Diaphorina citri Kuwayama (Hemiptera: Psyllidae) and Tamarixia radiata (Waterston) (Hymenoptera: Eulophidae) was recorded in citrus crops of Cundinamarca, Colombia. This work is to know the geographic distribution of D. citri and an initial record of the parasitoid T. radiata in citrus producing areas of this department.
