Sex pheromones, typically released by females are crucial signals for the reductive biology of insects, primarily detected by sex pheromone receptors (PRs). A clade of PRs in three mirid bugs, Apolygus lucorum, Adelphocoris lineolatus, and Adelphocoris suturalis, has been found to respond to pheromones, (E)-2-hexenyl butyrate (E2HB) and hexyl butyrate (HB), with higher sensitivity to E2HB. In this study, we aimed to identify PRs responsible for the other two pheromone components, HB and (E)-4-oxo-2-hexenal (4-OHE), by using a combination of phylogenetic analyses, sequence similarity analyses, and in vitro functional studies.

Article Synopsis
  • The genus Alternaria includes important fungal pathogens that affect various organisms, with a focus on a new mycovirus discovered from a strain isolated from diseased tobacco leaves in China.
  • This mycovirus, named Alternaria botybirnavirus 2 (ABRV2), has a genome made up of two dsRNA components, with lengths of 6,162 bp and 5,865 bp.
  • The dsRNAs encode hypothetical proteins that share a percentage of amino acid sequence similarity with proteins from a related virus, indicating that ABRV2 is a new member of the Botybirnavirus genus.

Ethnopharmacological Relevance: Honey-processed licorice (HPL) is the roasted product of licorice. It is recorded in the "Shang Han Lun" that licorice has better protection on heart after honey-processed. However, researches regarding its protective effect on the heart and the distribution of HPL in vivo are still limited.

Deoxynivalenol (DON) is a mycotoxin widely detected in cereal products contaminated by Fusarium pseudograminearum megabirnavirus 1 (FpgMBV1) is a double-stranded RNA virus infecting . In this study, it was revealed that the amount of DON in was significantly suppressed by FpgMBV1 through a high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) assay. A total of 2564 differentially expressed genes were identified by comparative transcriptomic analysis between the FpgMBV1-containing strain FC136-2A and the virus-free strain FC136-2A-V.

Star anise (Illicium verum) production is an important industry in parts of southern China (Wang et al. 2011). The production of star anise (cultivar Dahong) was seriously affected by a leaf spot disease during the summer of 2020 in Rong County, Guangxi province, China.

Mirid bugs are a group of important insect pests that cause large annual losses in agricultural production. Many studies have focused on the isolation and identification of sex pheromones in mirid bugs, and the components and biological activity of the sex pheromones have also been studied as a way to control these pests. However, few studies have focused on the mechanisms of pheromone perception.

Finding a suitable oviposition site is a challenging task for a gravid female moth. At the same time, it is of paramount importance considering the limited capability of most caterpillars to relocate to alternative host plants. The hawkmoth, (Sphingidae), oviposits on solanaceous plants.

Apolygus lucorum (Meyer-Dür) (Hemiptera: Miridae) is a serious pest of cotton, jujube, grape and many other crops around the world. Understanding how olfactory information directs this insect to its host plants may provide environment-friendly approaches to the control of its population in agriculture. In our study, we cloned an odorant receptor gene, AlucOR46, that was specifically expressed in antennae and female-biased.

Apolygus lucorum (Meyer-Dür) (Hemiptera: Miridae) is one of the most serious agricultural pests, feeding on a wide range of cultivated plants, including cotton, cereals and vegetables in the north of China. This insect can frequently switch between habitats and host plants over seasons and prefer plants in bloom. A.

Male moths can finely discriminate the sex pheromone emitted by conspecific females from similar compounds. Pheromone receptors, expressed on the dendritic membrane of sensory neurons housed in the long trichoid sensilla of antennae, are thought to be associated with the pheromone reception. In this study, we identified and functionally characterized 4 pheromone receptors from the antennae of Spodoptera litura (Lepidoptera: Noctuidae).
