herbivore-induced plant volatiles accurately predict history of coexistence, diet breadth, and feeding mode of herbivores.	herbivore-induced plant volatiles (hipvs) serve as specific cues to higher trophic levels. novel, exotic herbivores entering native foodwebs may disrupt the infochemical network as a result of changes in hipv profiles. here, we analysed hipv blends of native brassica rapa plants infested with one of 10 herbivore species with different coexistence histories, diet breadths and feeding modes. partial least squares (pls) models were fitted to assess whether hipv blends emitted by dutch b. rapa diffe ...	2017	28134434
sequential above- and belowground herbivory modifies plant responses depending on herbivore identity.	herbivore-induced changes in plant traits can cause indirect interactions between spatially and/or temporally separated herbivores that share the same host plant. feeding modes of the herbivores is one of the major factors that influence the outcome of such interactions. here, we tested whether the effects of transient aboveground herbivory for seven days by herbivores of different feeding guilds on tomato plants (solanum lycopersicum) alters their interaction with spatially as well as temporall ...	2017	28178961
possible insecticidal mechanisms mediated by immune-response-related cry-binding proteins in the midgut juice of plutella xylostella and spodoptera exigua.	cry toxins are insecticidal toxin proteins produced by a spore-forming gram-positive bacterium bacillus thuringiensis. interactions between the cry toxins and the receptors from midgut brush border membrane vesicles (bbmvs), such as cadherin, alkaline phosphatase, and aminopeptidase, are key steps for the specificity and insecticidal activity of cry proteins. however, little is known about the midgut juice proteins that may interfere with cry binding to the receptors. to validate the hypothesis ...	2017	28231709
high bacterial agglutination activity in a single-crd c-type lectin from spodoptera exigua (lepidoptera: noctuidae).	lectins are carbohydrate-interacting proteins that play a pivotal role in multiple physiological and developmental aspects of all organisms. they can specifically interact with different bacterial and viral pathogens through carbohydrate-recognition domains (crd). in addition, lectins are also of biotechnological interest because of their potential use as biosensors for capturing and identifying bacterial species. in this work, three c-type lectins from the lepidoptera spodoptera exigua were pro ...	2017	28257054
an entomopathogenic bacterium, xenorhabdus hominickii anu101, produces oxindole and suppresses host insect immune response by inhibiting eicosanoid biosynthesis.	an entomopathogenic bacterium, xenorhabdus hominickii anu101, was isolated from an entomopathogenic nematode, steinernema monticolum. x. hominickii exhibited significant insecticidal activities at ≥6.6×10(2) colony-forming units per larva against a lepidopteran insect, spodoptera exigua with hemocoelic injection. the insecticidal activity of x. hominickii was reduced by an addition of arachidonic acid (aa, a catalytic product of pla2), but enhanced by an addition by dexamethasone (dex, a specifi ...	2017	28302381
specificity of induced resistance in the tomato, lycopersicon esculentum.	specificity in the induced responses of tomato foliage to arthropod herbivores was investigated. we distinguished between two aspects of specificity: specificity of effect (the range of organisms affected by a given induced response), and specificity of elicitation (ability of the plant to generate distinct chemical responses to different damage types). specificity of effect was investigated by examining the effect of restricted feeding by helicoverpa zea on the resistance of tomato plants to an ...	1997	28307296
the defensive function of ni in plants: response of the polyphagous herbivore spodoptera exigua (lepidoptera: noctuidae) to hyperaccumulator and accumulator species of streptanthus (brassicaceae).	metals sequestered by plants may defend them against herbivores and/or pathogens. we explored the effect of plant metal content on a polyphagous herbivore, spodoptera exigua. plant experiments used a ni hyperaccumulator (streptanthus polygaloides) and two ni accumulator species (s. breweri and s. tortuosus). high- and low-ni plants of each species were produced by growing plants on either ni-amended or unamended soil. mean leaf ni contents for plants grown on ni-amended soil and control soil, re ...	1999	28307697
p143 proteins from heterologous nucleopolyhedroviruses induce apoptosis in bm-n cells derived from the silkworm bombyx mori.	we previously demonstrated that ribosomal rna (rrna) of bombyx mori bm-n cells is rapidly degraded upon infection with heterologous nucleopolyhedroviruses (npvs), including autographa californica multiple npv (acmnpv), hyphantria cunea mnpv, spodoptera exigua mnpv and s. litura mnpv, and that this response is triggered by viral p143 proteins. the transient expression of p143 proteins from heterologous npvs was also shown to induce apoptosis and caspase-3-like protease activation in bm-n cells. i ...	2017	28315706
aminopeptidase n1 is involved in bacillus thuringiensis cry1ac toxicity in the beet armyworm, spodoptera exigua.	understanding how insecticidal proteins from the bacterium bacillus thuringiensis (bt) interact with their hosts is crucial to fully explain the molecular bases of bt specificity and insecticidal activity. previous studies support atp binding cassette transporters (abcc2/3) and one cadherin-like protein are cry1ac functional receptors in the beet armyworm (spodoptera exigua). in this study, a combined one-dimensional gel electrophoresis and immunoblotting approach identified aminopeptidase n (ap ...	2017	28327568
molecular identification of differential expression genes associated with sex pheromone biosynthesis in spodoptera exigua.	species-specific sex pheromone is biosynthesized and released in most female moths as a chemical cue in mating communication. however, information on genes involved in this pathway is limited. the beet armyworm, spodoptera exigua, is a cosmopolitan agricultural pest that causes severe economic losses to many crops. in china, the female sex pheromones in sex pheromone glands (pgs) of s. exigua have been measured which comprises (z,e)-9,12-tetradecadienyl acetate, (z)-9-tetradecen-l-ol, (z)-9-tetr ...	2017	28349297
functional characterization of the aspartic proteinase cathepsin d in the beet armyworm (spodoptera exigua).	in insects, proteolytic enzymes are involved in food digestion and the metamorphosis process. in the present study, the full-length cdna of an aspartic proteinase, spodoptera exigua cathepsin d (secatd), was cloned, and its functions in metamorphosis were characterized. secatd contains an open reading frame of 1152 nucleotides, encoding a 384-amino acid polypeptide including a signal peptide and two functional domains (family a1 propeptide of amino acids (19-45) and a cathepsin d-like domain of ...	2017	28351737
mtase domain of dendrolimus punctatus cypovirus vp3 mediates virion attachment and interacts with host alp protein.	dendrolimus punctatus cypovirus (dpcpv) is an important pathogen of d. punctatus, but little is known about the mechanisms of dpcpv infection. here, we investigated the effects of vp3, vp4 and vp5 structural proteins on the viral invasion. both the c-terminal of vp3 (methyltransferase (mtase) domain) and vp4 (a-spike) bound to spodoptera exigua midgut brush border membrane vesicles (bbmvs) in a dose-dependent manner, and the binding was inhibited by purified dpcpv virions. importantly, anti-mtas ...	2017	28368302
development and survival of spodoptera exigua (lepidoptera: noctuidae) on alternate crops in cotton cropping pattern, with implications to integrated pest management.	spodoptera exigua (hübner) is a polyphagous pest that shifts its population to different hosts during its life cycle to receive nutritive advantages. therefore, demographic evaluation of alternate hosts is important for effective pest management. here, we have evaluated castor (ricinus communis l.), cauliflower (brassica oleracea l.), cotton (gossypium hirsutum l.), okra (abelmoschus esculentus l.), and spinach (spinacia oleracea l.) for growth, survival, and population development of s. exigua. ...	2017	28383691
