1. Efficacy of Trichogrammatidae Species (Hymenoptera) Submitted to the Herbicide Glyphosate
RESUMO: Informações sobre herbicidas seletivos, incluindo o glyphosate, que não afetam organismos não alvo, como inimigos naturais, são importantes nos programas de manejo integrado de pragas na cultura do milho. O glyphosate, na dose de 13,94 L ha-1, foi avaliado em fêmeas de 10 espécies de Trichogrammatidae (Hymenoptera). Uma fêmea de cada espécie

2. Occurrence of Amblycerus species in Cordia trichotoma seeds and their influence on germination
ABSTRACT Forest species can have their seeds damaged by granivorous insects, especially by those in their larval stage. In this context, this study aims to report the occurrence of Amblycerus species in Cordia trichotoma seeds, to describe their main damage to seeds and effects on germination, as well as their associated hymenopteran parasitoids. Therefore,

4. Selection of Trichogramma species as potential natural enemies for the control of Opogona sacchari (Bojer)
ABSTRACT: The banana moth Opogona sacchari (Bojer) (Lepidoptera: Tineidae) is a polyphagous pest that can cause serious damage, especially to banana crops in southern Brazil. It attacks the fruit, lowering its quality and making bananas unsuitable for export. Current control measures are limited and the use of Trichogramma (Hymenoptera: Trichogrammatidae) fo

5. Size and flight ability of Telenomus remus parasitoids reared on eggs of the factitious host Corcyra cephalonica
ABSTRACT In two independent bioassays, size and flight ability of parasitoids reared on eggs of Corcyra cephalonica for 19 generations and parasitoids reared on a natural host (Spodoptera frugiperda eggs) for 250 generations were compared as fast quality control procedures for insect rearing. The size of parasitoids was examined by morphometric analysis usin

6. Two new species of Emersonella (Hymenoptera: Eulophidae: Entedoninae) from the Brazilian Atlantic Forest
Emersonella Girault, 1916 is a wasp genus including species that parasitize Chrysomelidae (Coleoptera) eggs, mainly Cassidinae. It occurs only in the Americas, and is primarily distributed in the Neotropical Region. In this paper two new species of Emersonella from the Atlantic Forest of southeastern Brazil are described and compared to similar species. Emer

7. Egg parasitoids of Edessa meditabunda (Fabricius) (Pentatomidae) in lettuce crop
Egg parasitoids of Edessa meditabunda (Fabricius) (Pentatomidae) in lettuce crop. This study evaluated the occurrence of parasitoids in eggs of the stink bug, Edessa meditabunda (Fabricius, 1794) (Heteroptera, Pentatomidae) found on lettuce crop in Mato Grosso State, Brazil. Samples were collected in the vegetable garden "Cheiro Verde", in the municipality o

8. Natural incidence of egg parasitoids of Edessa meditabunda (F.) (Hemiptera: Pentatomidae) on Crotalaria spectabilis in Campo Novo do Parecis, MT, Brazil
Egg parasitoids of the stink bug Edessa meditabunda (F) were studied on rattlepod Crotalaria spectabilis used in soybean crop rotation in Campo Novo do Parecis, Mato Grosso state, central western Brazil. Seven species of parasitoids were found: two Encyrtidae, one Eurytomidae, and four Platygastridae. The occurrence of Trissolcus euchisti (Ashmead) and Triss

9. Egg parasitoid wasps as natural enemies of the neotropical stink bug Dichelops melacanthus.
Abstract ? The objective of this work was to determine the potential of five species of Scelionidae wasps ? Telenomus podisi, Trissolcus basalis, Trissolcus urichi, Trissolcus teretis and Trissolcus brochymenae ? as natural enemies of the neotropical stink bug Dichelops melacanthus, and to determine if the presence of eggs of other stink bug species influenc

10. Factors affecting attack rate of whitefly on the eggplant.
The objective of this study was to determine the effects of weather, predators and parasitoids, canopy height and plant age, leaf chemical composition, levels of leaf N and K and leaf trichomes on the intensity of Bemisia tabaci attack on Solanum melongena. A higher density of nymph and whitefly adults was recorded at the base and medium of the plant compare

12. Effect of Telenomus remus Nixon (Hymenoptera:scelionidae) density on control of Spodoptera frugiperda (Smith) (Lepidoptera: noctuidae) egg masses upon release in a maize field.
The impact of releasing different densities (0, 6, 9 and 12 adult females m-2) of the egg parasitoid Telenomus remus Nixon on maize plants artificially infested with Spodoptera frugiperda (Smith) egg masses (one m-2) was evaluated. Egg masses were pinned in the mid-rib of the plant 36 days after planting. One egg mass contained approximately 65 eggs. The exp
