A reliable bioassay procedure to evaluate per os toxicity of Bacillus thuringiensis strains against the rice delphacid, Tagosodes orizicolus (Homoptera: Delphacidae)
(Universidad de Costa Rica, 2007)
A reliable bioassay procedure was developed to test ingested Bacillus thuringiensis (Bt) toxins on the rice delphacid Tagosodes orizicolus. Initially, several colonies were established under greenhouse conditions, using ...
Soybean protease inhibitors increase Bacillus thuringiensis subs. israelensis toxicity against Hypothenemus hampei
(2020)
The coffee berry borer (Hypothenemus hampei Ferrari, CBB) is one of the most devastating pests on coffee plantations around the world. Although CBB is susceptible to the effect of δ–endotoxins ...
External Morphology of Tagosodes orizicolus (Homoptera: Delphacidae) Revealed by Scanning Electron Microscopy
(2001)
A comprehensive analysis of the ultrastructure of the delphacid rice pest Tagosodes
orizicolus (Muir) was undertaken using scanning electron microscopy to resolve taxonomic problems in the distinction of females and nymphs ...
Messua sp. (Salticidae), the host spider of the polysphinctine Inbioia pivai (Ichneumonidae: Pimplinae)
(2019)
The koinobiont ectoparasitoids of spiders in the Polysphincta genus group are divided into two well-supported clades. Species in one clade parasitize spiders in the higher araneoid group, and the behaviour of these ...
Patrones de coloración en Hymenoptera: su origen, evolución y posible función en miras a la aplicación biomimética
(2020-04-28)
El presente estudio proporciona la primera caracterización física y funcional del patrón negro-naranja-negro (BOB) que se encuentra en avispas parasitoides de muy pequeño tamaño (3-10 mm). Aunque se había reportado previamente ...
Connecting biology, optics and nanomechanical properties in micro-wasps
(2020)
Coloration in insects provides a fruitful opportunity for interdisciplinary research involving both physics and biology, and for a better understanding of the design principles of biological structures. In this research ...
Spectral measure of color variation of black-orange-black (BOB) pattern in small parasitoid wasps (Hymenoptera: Scelionidae), a statistical approach
(2019)
Small parasitoid wasps are abundant and extremely diverse, yet their colors have not been analyzed. One of the more common color patterns observed in these wasps is a black-orange-black pattern, which is especially common ...
Widespread Occurrence of Black-Orange-Black Color Pattern in Hymenoptera
(2019)
Certain color patterns in insects show convergent evolution reflecting potentially important biological functions,
for example, aposematism and mimicry. This phenomenon has been most frequently documented in Lepidoptera
and ...
First evidence for an aposematic function of a very common color pattern in small insects
(2021-02-11)
Many small parasitoid wasps have a black head, an orange mesosoma and a black metasoma (BOB color pattern), which is usually present in both sexes. A likely function of this widespread pattern is aposematic (warning) ...
Búsqueda y caracterización de proteínas biopesticidas novedosas a partir de cepas de Bacillus thuringiensis
(1999)
En la actualidad se desarrollan y se cultivan comercialmente plantas transgénicas que expresan endotoxinas de Bacillus thuringiensis (Bt) como biopesticida para el control específico de insectos. Sin embargo, se teme que ...
