Plants produce chemical defenses that poison insect herbivores or deter their feeding, but are also accompanied by microbial endosymbionts crucial for nutrition, reproduction, and fitness. Hence, plant could target a herbivore's beneficial endosymbionts, this has not yet been demonstrated. Here, we studied flavonoids induced when rice is attacked phloem-feeding pest, the brown planthopper (BPH), which harbors yeast-like symbionts (YLS) essential such as remedying deficiencies in sterols. BPH...
ABSTRACT Most associations between animals and their gut microbiota are dynamic, involving sustained transfer of food-associated microbial cells into the shedding microorganisms external environment with feces, but interacting effects host factors on composition internal communities poorly understood. This study laboratory cultures fruit fly Drosophila melanogaster reared in continuous contact food revealed time-dependent changes that were strongly influenced by presence abundance . When...
Spodoptera frugiperda is a significant migratory invasive pest, identified as serious threat to agricultural production and food security in China. However, our knowledge, the effects of most host plants on biological characteristics S. have not been well studied. To develop effective management strategies for its new habitat, basic ecological knowledge this pest are crucial requirements. Here, we examined six cash crops maize, wheat, soybean, tomato, cotton Chinese cabbage development,...
The resident microbiota of animals represents an important contribution to the global microbial diversity, but it is poorly known in many animals. This study investigated bacterial diversity plant phloem-sap-feeding whiteflies, aphids and psyllids by pyrosequencing 16S rRNA gene amplicons. After correction for sequencing error, just 3-7 operational taxonomic units were recovered from each insect sample sequenced sufficient depth saturation rarefaction curves. Most samples dominated primary...
The fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), is a significant invasive pest identified as serious threat to global agricultural production and food security. However, its ovipositional preference, larval feeding selectivity, nutritional indices are less studied. Here, we investigated these traits of FAW when fed on maize, wheat, soybean, tomato, cotton, Chinese cabbage, analyzed the correlation between contents crops. results showed that highest number eggs were laid maize...
Abstract Olfaction and gustation play critical roles during the host-location search process of insects. Several chemosensory receptor genes are thought to be involved in providing specificity olfactory sensory neuron responses. The aphid endoparasitoid, Aphidius gifuensis , has been used as a biological control agent against variety species; this parasitoid is able detect its target host(s) effectively parasitic process. To understand mechanism host detection A . we assembled specific...
Abstract The high osmotic pressure generated by sugars in plant phloem sap is reduced phloem‐feeding aphids sugar transformations and facilitated water flux the gut. genes mediating these osmoregulatory functions have been identified validated empirically pea aphid Acyrthosiphon pisum : sucrase 1 ( SUC1 ), a glycoside hydrolase family 13 (GH13), aquaporin AQP1 member of Drosophila integral protein (DRIP) aquaporins. Here, we describe molecular analysis GH13 AQP representatives four groups:...
Insect glutathione S-transferases (GSTs), a multifunctional protein family, play crucial role in detoxification of plant defensive compounds. However, they have been rarely investigated Sitodiplosis mosellana, destructive pest wheat worldwide. In this study, we characterized for the first time delta (SmGSTd1) and two epsilon GST genes (SmGSTe1 SmGSTe2) analyzed their expression patterns functions associated with adaptation to host defense species.
Low proportion of essential amino acids (EAAs) is one the barriers for animals to use phloem as a diet. Endosymbionts with EAAs synthesis functions are considered crucial ameliorating lack in insects' diets. In this study, we transferred insects from cabbage-reared Myzus persicae population onto 3 new plant species including eggplant, tobacco and spinach. The performance on these plants was evaluated dynamics endosymbionts relation host alternation were recorded. We found that ratio largely...
Abstract Mythimna separata (Walker) (Lepidoptera: Noctuidae) is one of the most destructive phytophagous pests. Here we present detailed instructions to achieve successful application CRISPR/Cas9‐mediated genome editing on M. . We optimized procedures, including egg collection and incubation. further successfully conducted microinjection washed eggs by applying water surface. then evaluated effects injection timing both viability efficiency using NPC1b as target gene. observed that Cas9...
Abstract BACKGROUND Insects cannot synthesize sterols and must acquire them from food. The mechanisms underlying how insects uptake dietary are largely unknown except that NPC1b, an integral membrane protein, has been shown to be responsible for cholesterol in Drosophila melanogaster . However, whether NPC1b orthologs other insect species, particularly the economically important pests, function similarly remains determined. RESULTS In this study, we characterized of Helicoverpa armigera , a...
The pea aphid, Acyrthosiphon pisum (Harris) (Hemiptera: Aphididae), shows wing polyphenism (winged and wingless morphs) in its life cycle. winged morph is adapted for dispersal; two developmental adult stages (for dispersal reproduction) are based on breeding periods. morphs show different phototactic behavior the can change preference to light according stages. To determine mechanism ecological functions of phototaxis A. pisum, we first investigated aphid at analyzed response lights...
