Abstract A new species of microgastrine wasp, Cotesia invirae Salgado-Neto & Whitfield, sp. nov., is described from southern Brazil in Santa Maria, Rio Grande do Sul. This species is a koinobiont gregarious larval endoparasitoid and spins a common mass of cocoons underneath the host caterpillars of Opsiphanes invirae (Huebner, 1818) (Lepidoptera: Nymphalidae), feeding on the palm trees Syagrus romanzoffianum (Cham.) Becc.; Livistona chinensis (N.J. Jacquim) R. Brown; Roystonea regia (HBK) O.F. Cook; Archontophoenix cunninghamiana Wendland & Drude (Palmaceae). Morphological, molecular, biological, ecological and geographical data are integrated to describe the new species.

Abstract A new species of Diolcogaster (Hymenoptera: Braconidae) is described and illustrated. Additionally, its position within the recently published key to New World species of the xanthaspis species-group (to which the described Diolcogaster belongs) is provided. The gregarious larval parasitoid Diolcogaster choi sp. nov. was collected in Maringá, Paraná State, Brazil. This natural enemy was recovered from a caterpillar of Hypercompe cunigunda (Stoll, 1781) (Lepidoptera: Erebidae) that was feeding on plant of passionflower, Passiflora edulis Sims (Passifloraceae). The fauna of the xanthaspis group in the New World now includes five species, including the new species from Brazil described in this paper. Diolcogaster choi sp. nov. differs anatomically,...

ABSTRACT A new species of Diolcogaster (Ashmead, 1900) (Hymenoptera: Braconidae) is described and illustrated. Additionally, a key to all New World species formally published of the xanthaspis species-group (to which the new species belongs) is provided. The solitary larval parasitoid Diolcogaster flammeus sp. nov. was collected in Viçosa, Minas Gerais State, Brazil. This natural enemy was reared from caterpillars of Agaraea minuta (Schaus, 1892) (Lepidoptera: Erebidae) feeding on plants of spiked spiralflag ginger, Costus spicatus (Jacq.) Sw. and ginger spiral, Costus spiralis (Jacq.) Roscoe var. spiralis (Costaceae). The fauna of the xanthaspis group in the New World included just three published species prior to this publication. Diolcogaster flammeus...

ABSTRACT: This note is the first report on the infection of adult stage of Melanagromyza sojae Zehntner, 1900 (Diptera: Agromyzidae) by the entomopathogenic fungus Ophiocordyceps dipterigena (Hypocreales: Ophiocordycipitaceae) (Berk. & Broome) G. H. Sung, J.M. Sung, Hywel-Jones & Spatafora, in subtropical Brazil. Entomopathogenic fungi, which attack dipteran insects, are of great scientific and economic importance mainly due to their potential as biological control agents of insect pests. Our findings bring new perspectives on the geographical distribution and host range of Ophiocordyceps dipterigena. We emphasize the need of further studies and research on new biological control agents of agricultural pests such as the soybean stem miner fly.

Salgado-Neto,Geraldo.

Xanthozona melanopyga (Wiedmann, 1830) (Diptera: Tachinidae) is recorded here as a parasitoid of Brassolis astyra Godart, 1824 (Lepidoptera: Nymphalidae). Dipteran endoparasitoids have been recorded as pupal endoparasitoids of Brassolis sophorae (L.), due to the scientific and economic importance of these interespecific relationships, and aiming to increase the knowledge on natural and conservative biological control, I hereby record Xanthozona melanopyga (Wiedmann) as larval-pupal parasitoid of Brassolis astyra Godart for the State of Rio Grande do Sul, Brazil. For the first time.

First report of parasitism on pupae of Opsiphanes invirae amplificatus Stichel (Lepidoptera, Nymphalidae) by Conura (Conura) maculata (Fabricius) (Hymenoptera, Chalcididae) in Rio Grande do Sul, Brazil. This scientific note records the parasitism on pupae of Opsiphanes invirae amplificatus Stichel (1904) by Conura (Conura) maculata (Fabricius). This is a report of this interaction in the subtropical region of South America and the first report of the occurrence of this parasitoid in the state of Rio Grande do Sul, Brazil.

This note is the first report on the infection of Diloboderus abderus Sturm (Coleoptera: Melolonthidae) larvae by the fungusOphiocordyceps melolonthae (Hypocreales: Ophiocordycipitaceae) in subtropical Brazil. Identification was made possible by extraction and sequencing of the fungal DNA that was covering the larvae’s mouthparts, prothorax, cuticle, and digestive tract (alimentary canal). Amplification, sequencing and comparison of the ITS region of the ribosomal DNA with voucher sequences of GenBank were performed and were 95% similar to Ophiocordyceps melolonthae. The fungus is an entomopathogen which attacks Melolonthidae larvae, having scientific and economic importance because of the need for increased knowledge on its distribution and on...

ABSTRACT: The scientific and economic importance of soybean root rot justifies the study of this disease, especially the role of insects as dispersers in the spread of root pathogens. The objective was to identify and evaluate qualitatively and quantitatively the role of Cyclocephala modesta, Dyscinetus gagatesand Diloboderus abderus(Coleoptera: Melolonthidae) in the dispersion of root pathogens in cultivated fields. The fungi were identified to the species level with DNA extraction and sequencing of these organisms within Melolonthidae larvae. Larvae were dissected and separated into the parts: mouth parts, prothorax, cuticle and digestive tract (alimentary canal). The Internal Transcribed Spacer region of the rRNA was amplified and compared to sequences...

ABSTRACT: This study investigated the natural parasitism of Mythimna sequax Franclemont, 1951, in wheat during the crop season of 2008. In total, 237 larvae were captured, of which 10.12% were parasitized. The Tachinidae species Winthemia trinitatis (Thompson, 1963), Winthemia tricolor (Wulp, 1890), Lespesia aletiae (Riley, 1879), and Lespesia archippivora Beneway, 1963 are reported for the first time parasitizing the wheat armyworm in Brazil. In addition, two other genus of parasitoids were identified, one Tachinidae Peleteria Robineau-Desvoidy, 1830 and one Ichneumonidae Ophion (Fabricius, 1798). This study reported for the first time four Tachinidae species parasitizing W. sequax, and further studies are needed to promote the conservation of these...

Syntomopus parisii and Leptomeraporus sp. parasitizing Melanagromyza sojae in Brazil

Salgado-Neto,Geraldo; Palma,Janine; Costa,Valmir Antonio.

ABSTRACT: This note is the first report of Syntomopus parisii De Santis 1976 and Leptomeraporus sp. (Hymenoptera, Pteromalidae) simultaneously parasitizing Melanagromyza sojae Zehntner, 1900 (Diptera, Agromyzidae) in Brazil. The Pteromalidae parasitoids are natural enemies of stem miner flies, opening perspectives for biological control of soybean stem miner fly.

ABSTRACT: The occurrence of white grub roots in soybean crops in the South of Brazil has gradually increased. However, there is not information on the biological control of grubs by entomopathogenic fungi. This study aimed to induce infection by Ophiocordyceps melolonthae and analyze longevity in Cyclocephala modesta and Dyscinetus gagates larvae (Coleoptera: Melolonthidae). In the laboratory, Cyclocephala modesta and Dyscinetus gagates had a mortality rate of 85% and 75%, respectively.
