Biologia de Neotrioza tavaresi Crawford, 1925 (Hemiptera, Psyllidae), galhador da folha do araçazeiro (Psidium cattleianum)

Biology of the leaf gall inducer Neotrioza tavaresi Crawford, 1925 (Hemiptera, Psyllidae) on strawberry guava tree (Psidium cattleianum). A field study was conducted in Curitiba region, State of Paraná, southern Brazil, to describe the life cycle of Neotrioza tavaresi Crawford, 1925, a leaf galling insect in strawberry guava trees (Psidium cattleianum). Three cycles were observed (1997, 1998, 1999) during regular field trips and the insects were observed in Piraquara municipality, where 15 samples with 50 infested leaves were sampled in the 1997-98 cycle. Galls were dissected for detailed studies. Neotrioza tavaresi has a univoltine cycle in which adult individuals were found inside the galls from August onwards. The sexually mature insects with sex ratio 1, emerged from the galls after their dehiscence caused by feeding of the adult insects on the gall walls. Adult emergence started in early October and ended by early December, with its peak in November. Copulation took place as soon as adults exit the gall and egg laying started the next day. Females had more than 100 ovarioles containing 218.7±44.7 (n=50) fully formed eggs. This indicated the short sexual adult life-span (aprox. 5-7 days) of the species, also characterized by a concentrated oviposition. Adult individuals fed and laid their eggs on younger shoots of the plant. The bottoms of the yellowish eggs were inserted into the leaf tissue, mainly on its adaxial edge (78.1%). The nymphs hatched and, as they fed on the adaxial side of expanding leaves, modified the cell growth pattern and the round-shape galls developed on the adaxial side with one insect inside. The gall wall showed distinct layers, with the inner one suppliyng the food to the insects, and the outer layer supplying gall protection. Nymphs went through five instars and the exuviae remained stuck on a ball of wax inside the gall. All parasitoids found were Hymenoptera belonging to Chalcidoidea: Eulophidae (1 sp), Pteromalidae (2 spp) and Encyrtidae (3 spp). The findings suggest that leaf gall inducer and parasitoids insects and plant life cycles are closely connected and both leaf sprouting and gall opening seem to be triggered by the same environmental and plant conditions. The high abundance of shoots may favor insect performance as adult individuals can easily find an ideal place for feeding, copulating and laying eggs.

Partamona nigrilabris Pedro & Camargo, 2003, um novo sinônimo de P. nigrior (Cockerell, 1925) (Hymenoptera, Apidae)

P. nigrilabris was described based on specimens wrongly labelled as from "Salvador-BA, Brasil". It is considered as a new synonym: Partamona nigrior (Cockerell, 1925) = P. nigrilabris Pedro & Camargo, 2003, syn. nov.

Drosophila angustibucca Duda sensu Frota-Pessoa is an undescribed species (Diptera, Drosophilidae)

Drosophila nappae sp. nov. , belonging to the subgroup I of the Drosophila tripunctata species group of the subgenus Drosophila, is described from flies of one strain established from several females collected from July 1994 through April 1995 at Morro Santana, Porto Alegre, state of Rio Grande do Sul, Brazil. This species has been misidentified during the past fifty years as Drosophila angustibucca (sensu Frota-Pessoa, 1954; non Duda, 1925, described from Costa Rica). Illustrations of male and female terminalia are also provided.
