Braz. j. biol; 84 (), 2024
Abstract Horismenus camobiensis sp. nov. (Hymenoptera: Eulophidae), is described based on morphological, molecular and ecological data; this new species of chalcid wasp acts as hyperparasitoid of Opsiphanis invirae (Hübner, 1818) (Lepidoptera: Nymphalidae) in its parasitoid Cotesia invirae Salgado-Neto ...

Notes on the biological development of the darkling beetle Blaps nefrauensis nefrauensis Seidlitz, 1893 (Coleoptera: Tenebrionidae)

Braz. j. biol; 82 (), 2022
Several endemic species of Blaps occur in Tunisia, and the species Blaps nefrauensis nefrauensis has been reported in Moulares (urban zone in west-central Tunisia), where it lives and reproduces in home gardens and old buildings. The aim of this work is to study the life cycle of the darkling beetle, con...

First list of parasitoids in flies of medical, veterinary, and forensic importance in Rio Grande do Sul - Brazil

Braz. j. biol; 82 (), 2022
Necrophagous flies are of great importance for human and animal health. In places where their development occurs, parasitoids can be used as a tool to control these dipterans. In Brazil, the fauna of these parasitoids has been investigated in some regions. However, in Rio Grande do Sul, it is known the o...

Tetrastichus howardi (Hymenoptera: Eulophidae): first report of parasitism in Oxydia vesulia (Lepidoptera: Geometridae)

Braz. j. biol; 81 (2), 2021
The adaptation of native lepidopteran species to eucalyptus plantations reduces the productivity of this crop in Brazil. Oxydia vesulia Cramer (Lepidoptera: Geometridae) is a secondary pest, frequently reported in eucalyptus plantations with population outbreaks and economic damages. Methods of biologica...

Entomopathogenic nematodes for the control of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) pupae

Arq. Inst. Biol; 88 (), 2021
Helicoverpa armigera (Hübner) is a polyphagous insect of difficult control and maize is an important host crop of this insect. Entomopathogenic nematodes (EPNs) are control agents of soil pests. This study aimed to verify the action of EPNs for the control of H. armigera pupae. Laboratory and greenhouse...

Standard culture of Paratanytarsus grimmii Schneider, 1885 (Diptera: Chironomidae), for its use in toxicity bioassays

Braz. j. biol; 80 (4), 2020
Abstract The management and use of native species under laboratory conditions is the main difficult for species proposal for its use in bioassays. The present study showed the results about management under controlled conditions of Paratanytarsus grimmii (Diptera: Chironomidae), that is a parthenogenetic...

Verification of atmospheric plasma irradiation as an alternative control method for Tribolium castaneum (Herbst)

Braz. j. biol; 80 (3), 2020
Abstract Radio frequency plasma, RF plasma, has been applied to a number of industrial applications. Laboratory experiments were conducted to determine the RF plasma potential in Tribolium castaneum (Herbst) control. Three treatment variables: (1) helium or argon plasmas; (2) two power levels (50 and 100...

Biology and External Morphology of the Immature Stages of Dirphia moderata Bouvier (Lepidoptera: Saturniidae: Hemileucinae) in Anacardium occidentale L

Abstract The genus Dirphia Hübner, [1819] presents Neotropical distribution. This genus, besides causing accidents of interest in public health, is a potential defoliator pest of cultivated plants, among them the cashew tree (Anacardium occidentale L.), a crop of great economic importance. This study d...

Palmistichus elaeisis (Hymenoptera: Eulophidae) rearing in Tenebrio molitor (Coleoptera: Tenebrionidae) submitted to different diets

Arq. Inst. Biol; 87 (), 2020
The ecological, physiological and behavioral processes of insects are linked to their nutrition. The diet of host insects can modify the development of natural enemies and affect their reproductive performance. The objective of this work was to evaluate the development and reproduction of Palmistichus el...
