Locust adults can form gregarious swarms and cause locust plagues. Few studies have evaluated the efficacy of a mixture two biocontrol agents for controlling adults. Here, we assessed effects protozoan agent, Nsoema locustae, fungal Aspergillus oryzae XJ-1, at ratios against in lab. Synergistic were observed (χ2 > χ2 (df, 0.05) Po PE). The maximum mortality caused by an N. locustae–A. XJ-1 was 92.67% on 12th day after inoculation, much higher than those each agent. In addition, median...
Insects have evolved sophisticated olfactory reception systems to sense exogenous chemical signals. Odorant receptors (ORs) on the membrane of chemosensory neurons are believed be key molecules in sensing cues. ORs different species insects diverse and should tune a its own specific semiochemicals relevant their survival. The orthopteran insect, locust (Locusta migratoria), is model hemimetabolous insect. There very limited knowledge functions although many OR genes been identified genomic...
Olfaction in animals is important for host localization, mating and reproduction heterogeneous chemical environments. Studying the molecular basis of olfactory receptor neurons (ORNs) systems can elucidate evolution olfaction associated behaviours. Odorant receptors (ORs) insects have been identified, particularly holometabolous model Drosophila, some them functionally studied. However, ORs locust-a hemimetabolous insect most crop pest-have not yet hindering our understanding locust...
A novel entomopathogenic fungus of Locusta migratoria was identified as Aspergillus oryzae using a comparative sequence analysis the internal transcribed spacer regions, aflatoxin B1 detection and morphological analysis. The isolated from dead locust collected in northwestern China found to be pathogenic insect. Phylogenetic experiments revealed 99% similarity between those three species, A. oryzae, flavus parvisclerotigenus which are same branch Flavi section genus Aspergillus. Tests detect...
Microsporidia are obligate intracellular parasites, existing in a wide variety of animal hosts. Here, we reported AlocSWP2, novel protein identified from the spore wall Antonospora locustae (formerly, Nosema locustae, and synonym, Paranosema locustae), containing four cysteines that conserved among homologues several Microspodian pathogens insects mammals. AlocSWP2 was detected mature spores via indirect immunofluorescence assay. In addition, immunocytochemistry localization experiments...
Locusts and grasshoppers are pests of many agricultural crops, their frequent outbreaks worldwide threaten food security. Microbial control agents currently used to suppress the early (nymphal) stages pests, but they often less effective against adults, which primarily responsible for locust plagues. The fungal pathogen Aspergillus oryzae XJ-1 has high pathogenicity in nymphs. To assess its potential controlling we evaluated virulence A. (i.e., Aspergillus, LAsp) adults using laboratory,...
Biological control methods provide a sustainable approach for reducing agricultural losses caused by locust plagues. Space mutagenesis can generate high numbers of mutations using satellites and spacecrafts, including beneficial stable mutants. Aspergillus oryzae XJ-1 was recently reported to show virulence against locusts. We subjected this fungal pathogen space obtain more effective strains. Pathogen conidia powder mutated in the China Station 6 months. obtained five mutants A. XJ-1,...
is an excellent pollinator in nature and plays a vital role the conservation of agro-ecosystems food security. Given important gut bacterial community host health regulation growth development, using 16S rRNA gene sequencing data, present study explored composition its diversity at different life stages (eggs, young larvae, old pupae, 1-day-old adults cocoons) solitary bee
Fungi play an increasingly important role in the biological control of insect pests. Aspergillus oryzae XJ1 is highly virulent to locust adults and nymphs, which are a destructive economic pest worldwide. Because its host association with locusts, unique Aspergillus, this study, we examined genetic relationships A. within Aspergillus. We sequenced genome compared it genomes other species. The complete 37.9 Mb, comprising 11,720 putative genes, assembled into eight chromosomes. size similar...
The palps of locust mouthparts are considered to be conventional gustatory organs that play an important role in a locust's food selection, especially for the detection non-volatile chemical cues through sensilla chaetica (previously named terminal or crested sensilla).There is now increasing evidence these also have olfactory function.An odorant receptor (LmigOR2) and odorant-binding protein (LmigOBP1) been localized neurons accessory cells, respectively, basiconica palps.Single sensillum...
Insects have evolved sophisticated olfactory reception systems to sense exogenous chemical signals. These signals are transduced by Olfactory Receptor Neurons (ORNs) housed in hair-like structures, called chemosensilla, of the antennae. On ORNs' membranes, Odorant Receptors (ORs) believed be involved odor coding. Thus, being able identify genes localized ORNs is necessary recognize OR genes, and provides a fundamental basis for further functional situ studies. The RNA expression levels...
