Aphid parasitoids (Hymenoptera, Braconidae, Aphidiinae) and their associations related to biological control in Brazil Rev. Bras. entomol.
Starý,Petr; Sampaio,Marcus Vinicius; Bueno,Vanda Helena Paes.
This study evaluated the parasitoid-aphid-plant associations in Brazil with the objective of developing a useful research database for further studies of aphid parasitoid ecology and aphid management. The original material was obtained from collections made in Paraná, Rio Grande do Sul, Minas Gerais, and São Paulo states. The published information on the Aphidiinae in Brazil is revised. The general features of the target parasitoid fauna of Central and South America is summarized and promising biological control programs of some aphid species in Brazil is discussed.

Entomofauna associated to fruits and seeds of two species of Enterolobium Mart. (Leguminosae): harm or benefit? Rev. Bras. entomol.
Meiado,Marcos Vinicius; Simabukuro,Eliana Akie; Iannuzzi,Luciana.
Entomofauna associated to fruits and seeds of two species of Enterolobium Mart. (Leguminosae): Harm or benefit? The aims of the present study were to identify the entomofauna associated to the fruits and seeds of Enterolobium contortisiliquum (Vell.) Morong and Enterolobium timbouva Mart. (Leguminosae), as well as to determine relationships among insects and the possible harm and/or benefit stemming from these associations. Fruit infestation was evaluated and the insects were identified. Seed consumption (%) and the germination of predated seeds (%) were determined. The fruits of E. contortisiliquum exhibited a high percentage of infestation (91%). The most representative species in the fruits were Lophopoeum timbouvae Lameere, 1884, Merobruchus...

Biology and nutrition of Spodoptera frugiperda (Lepidoptera: Noctuidae) fed on different food sources Scientia Agricola
Silva,Débora Mello da; Bueno,Adeney de Freitas; Andrade,Karine; Stecca,Cristiane dos Santos; Neves,Pedro Manuel Oliveira Janeiro; Oliveira,Maria Cristina Neves de.
ABSTRACT: We studied Spodoptera frugiperda development using different food sources in the laboratory and field. Newly hatched larvae were fed soybean, cotton, maize, wheat, and oat leaves. An artificial diet was used as the control. Duration of pre-pupal, pupal, and larva-adult period, pupal weight, sex ratio, survival, larva feeding preferences, oviposition preferences, and nutritional quality of different hosts were evaluated. Insects fed on wheat showed the shortest larva-adult period. The insects fed on cotton and soybean had longer larval development cycles and pupae of lower weight. Feeding preference was evident for third instar larvae and did not differ between wheat, oat, maize, and soybean, which were the preferred hosts. Moths oviposited to a...

Levels of leaf Herbivory in Amazonian trees from different stages In forest regeneration Acta Amazonica
VASCONCELOS,Heraldo L..
Leaves from 120 canopy trees and 60 understory tree saplings growing in primary and secondary forests near Manaus, Brazil, were collected for determination of standing levels of herbivory (percent leaf area lost). Overall, levels of herbivory on leaves of central Amazonian trees were low. About one quarter of the leaves examined (n = 855) had no damage at all. In most other Neotropical sites studied the mean percentage of herbivory was found to vary between 5.7 and 13.1%, whereas in Manaus it was only 3.1%. The data presented here support the contention that levels of herbivore damage are positively related to soil fertility. No significant difference was found in herbivory levels between canopy trees and understory saplings. Also, there was no difference...

Insect Galls of the Parque Nacional do Itatiaia (Southeast Region, Brazil) Anais da ABC (AABC)
MAIA,VALÉRIA C.; MASCARENHAS,BERNARDO.
ABSTRACT The Parque Nacional do Itatiaia (PNI) (Brazilian Southeast Region) was surveyed monthly for insect galls from February/2014 to December/ 2015. A total of 432 gall morphotypes were found. This number places the PNI as the richest Atlantic forest area in number of gall morphotypes. The galls were found on 47 plant families. Among them, Asteraceae were pointed out as the superhost. The gall richness in the lower part of the PNI is higher than that of the plateau. The insect galls were found in 154 native, 56 endemic and only one exotic plant species. Concerning the conservational status, the host plants include two vulnerable species with three morphotypes together. Several new botanical records were reported. Leaves were the most galled plant organ,...

Relationships between four Neotropical species of galling insects and shoot vigor Anais da SEB
Gonçalves-Alvim,Silmary J.; Faria,Maurício L.; Fernandes,Geraldo W..
The plant-vigor hypothesis (PVH) predicts that females of galling insects preferentially oviposit on the most vigorous plant or plant modules, where their offspring performance is highest. We tested the PVH on Neopelma baccharidis Buckhardt (Homoptera: Psyllidae) and Rhoasphondylia friburgensis Tavares (Diptera: Cecidomyiidae) which induce galls on Baccharis dracunculifolia D.C. (Asteraceae), and on two different Cecidomyiidae (Diptera) species that induce galls on Maytenus salicifolia Reiss. (Celastraceae) and Vernonia polyanthes Less (Asteraceae), respectively. The abundance of galls induced by the four galling species increased with increasing shoot length, as predicted by the PVH. However, when we considered the rate of attack per shoot unit length...

Infestation of Mangroves by the Invasive Moth Hyblaea puera (Cramer, 1777)(Lepidoptera: Hyblaeidae) BABT
Faraco,Luiz Francisco Ditzel; Ghisi,Conrado Locks; Marins,Marina; Ota,Sueli; Schühli,Guilherme Schnell.
Abstract We report the first known infestation of mangroves by the invasive moth Hyblaea puera in Paraná, Southern Brazil. The infestation caused massive defoliation of Avicennia schaueriana trees, affecting approximately 20,000 hectares of mangroves. We discuss the implications for conservation and management, focusing on protected areas, the ecology of mangroves, and local livelihoods.

Characterization of resistance expression in genotypes of Solanum Section Lycopersicon against Tuta absoluta (Lepidoptera: Gelechiidae) Ciencia e Investigación Agraria
Vitta,Nancy; Estay,Patricia; Chorbadjian,Rodrigo A.
N. Vitta, P. Estay, and Chorbadjian, R.A. 2016. Characterization of resistance expression in genotypes of Solanum Section Lycopersicon against Tuta absoluta (Lepidoptera: Gelechiidae). Cien. Inv. Agr. 43(3):366-373. Two studies were conducted with the aim of characterizing the antixenosis and antibiosis resistance expression of genotypes in the Solanum section Lycopersicon against Tuta absoluta (Meyrick). The species used were S. lycopersicum (Fiorentino, Naomi and Belle), S. habrochaites (RCAT030597, PI126446), S. chilense (INIABB79), S. peruvianum (RCAT031296, RCAT039874 and RCAT030403) and S. pimpinellifolium (PI390739). For the antixenosis bioassay, a leaf was removed from plants of each genotype and placed in a cup with a floral foam soaked in water....
