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 ...
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 ...
Phenology of an urban population of Lyssomanes jemineus Peckham & Wheeler (Araneae: Salticidae) with a list of other jumping spiders from the same Costa Rican site
(2019)
Jumping spiders were sampled for 24 months in a Costa Rican urban environment and one
of the species collected, Lyssomanes jemineus, was observed in detail in order to document its
phenology in this disturbed habitat. ...
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 ...
New insights into the molecular phylogeny of the swimming crabs of the genera Portunus Weber, 1795 and Achelous De Haan, 1833 (Brachyura: Portunidae) of the Americas
(2018)
Earlier studies of swimming crabs (family Portunidae) in the Americas suggested polyphyly of Portunus Weber, 1795. Our previous molecular analyses provided evidence for a subdivision of the genus, resulting in a reassignment ...
Seagrass organic carbon stocks show minimal variation over short time scales in a heterogeneous subtropical seascape
(2018)
Blue carbon initiatives require accurate monitoring of carbon stocks. We examined sources of variability in seagrass organic carbon (Corg) stocks, contrasting spatial with short temporal scales. Seagrass morphology and ...
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 ...
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 ...
Richness of cultivable endophytic fungi along an altitudinal gradient in wet forests of Costa Rica
(2016-04)
We collected various plant species along an altitudinal gradient ranging from 400 to 2900 m in tropical wet forests of Costa Rica, isolated the associated endophytic fungi, and performed bioinformatic analyses to determine ...
Isolation of Flavonoids from Deguelia duckeana and Their Effect on Cellular Viability, AMPK, eEF2, eIF2 and eIF4E
(2016)
Preparations of Deguelia duckeana, known in Brazil as timbó, are used by indigenous people to kill fish. Reinvestigation of its extracts resulted in the isolation and identification of 11 known flavonoids identified as ...
