Apples are a fruit crop of economic and nutritional importance that require cross-pollination primarily by insects for sustainable production. It was recently demonstrated that nocturnal pollinators can contribute as much to apple pollination as diurnal pollinators. However, information concerning nocturnal pollinator identity, activity periods, and community composition in apples is lacking, which limits research expansion. To address this knowledge gap, nocturnal moths in an apple orchard were surveyed during apple bloom from 2018 to 2020 using blacklight traps, with samples collected hourly to delineate moth activity. Observations during the same periods were made to identify moths visiting apple flowers, whose capture data were then compared to other captured moth species to provide useful information concerning community composition during apple bloom. Blacklight surveys yielded 1,087 moths representing at least 68 species from 12 families, wherein 15 species from five families were observed visiting apple flowers. Captured moths were most abundant and diverse in the first two hours after sunset. Most captured moth species did not visit flowers and are likely not associated with apple pollination. However, moth species that were observed visiting flowers were the most abundant overall and most diverse by hour in surveys. Data indicate a rich moth community present among apple orchards during bloom and identify likely moth pollinators of apples. Though more research is required to establish the precise relationships between moth pollination and apples, the information provided here allows for targeted efforts to do so.

This review compiles information on the morphology, historical taxonomic treatments, species origin, gene pool concept, geographical and ecological habitats, and stress tolerance of the azuki bean () and related species. Willdenow (1802) first described the azuki bean in the genus , and Ohwi and Ohashi (1969) finally transferred it to the genus . The genus is currently divided into five subgenera: , , , , and .

The genus Lecanicillium was established in 2001 based on the type species Lecanicillium lecani (former, Verticillium lecani), which is an important entomopathogenic fungus. To date, more than thirty species in the genus have been reported, but much more are waiting to discover. In this study, two novel species isolated from soil in east China were identified.

Insects and flowering plants are the most abundant and diverse multicellular organisms on Earth, accounting for 75% of known species. Their evolution has been largely interdependent since the so-called Angiosperm Terrestrial Revolution (100-50 Mya), when the explosion of plant diversity stimulated the evolution of pollinating and herbivorous insects. Plant-insect interactions rely heavily on chemical communication via volatile organic compounds (VOCs).

In Drosophila, localized mRNA of serves as anterior determinant (AD). Bicoid engages in a concentration-dependent competition with nucleosomes and initiates symmetry-breaking along the AP axis by promoting chromatin accessibility at the loci of transcription factor (TF) genes that are expressed in the anterior of the embryo.
