Black cottonwood (Populus trichocarpa) is a species of economic interest and an outstanding study model. The aspen borer (Saperda calcarata) causes irreversible damage to poplars other riparian in North America. insect can produce multiple effects ranging from the presence some galleries stem tree death. Despite ecological commercial importance this tree–insect interaction, genetic mechanisms u...

Industrial valorization of proteins from traditional edible insects requires knowledge their nutritional, chemical, technological characteristics. Therefore, these characteristics in two Mexican (A. cordifera and B. mellifica) were studied compared to commercial insect species (H. illucens). The nutritional attributes protein concentrates (PCs) determined by content, amino acid polyphenol compo...

The ability of insects to persist in urban greenspace depends on their usefully interact with available plant resources. Greenspace design influences plant–insect interactions by: (1) limiting the plant-species pool for interaction through choice, (2) that are site-occupancy dynamics, and (3) mediating insect preferences based context particular structural barriers, microclimatic changes or com...

Insect diapause is a dynamic process consisting of several successive phases. The conception and naming of the phases is unsettled and, sometimes, ambiguous in the literature. In this paper, the ontogeny of diapause was reviewed and the most often used terms and the best substantiated phases were highlighted, explained and re-defined. The aim was to propose relatively simple and generally appli...

Symbiotic interactions between microorganisms and social insects have been described as crucial for the maintenance of these multitrophic systems, observed stingless bee Scaptotrigona depilis yeast Zygosaccharomyces sp. SDBC30G1. The larvae S. ingest fungal filaments SDBC30G1 to obtain ergosterol, which is precursor biosynthesis ecdysteroids that modulate insect metamorphosis. In this work, we ...

Three new papers report the long-awaited functional characterization of the Drosophila receptor for the circadian-rhythm-regulating signalling molecule PIGMENT DISPERSING FACTOR (PDF). The discovery of the PDF receptor heralds progress in understanding the circadian pacemaker circuit and output pathways in insects.
