The photos of adults, male and female genitalia, abdominal special structures are presented. species similar to N. meyricki Hering, 1925 sinensis Davis, 1975, but it can be distinguished easily by characters in genitalia as straight gnathos lateroposterior process anellus h-type bifurcated. Key males all Meyrick, 1909 some biological information also given. Molecular...

Multicellular eukaryotic organisms are attacked by numerous parasites from diverse phyla, often simultaneously or sequentially. An outstanding question in these interactions is how hosts integrate signals induced the attack of different parasites. We used a model system comprised plant host Arabidopsis thaliana, hemibiotrophic bacterial phytopathogen Pseudomonas syringae, and herbivorous larvae moth Trichoplusia ni (cabbage looper) to characterize mechanisms involved systemic-induced...

Abstract BACKGROUND Monitoring arthropod pests and their natural enemies provides essential information for pest control decisions in agricultural production. Traditional monitoring methods, such as trapping visual surveys, have practical limitations because of time‐consuming preprocessing steps the need knowledgeable taxonomists. We tested environmental DNA (eDNA) metabarcoding approach cowpea ( Vigna unguiculata ) across seven climatic sub‐regions China, comparing it with traditional...

Insect-specific ascoviruses with a circular genome are distributed in the USA, France, Australia and Indonesia. Here, we report first ascovirus isolation from Spodoptera exigua Hunan, China. DNA-DNA hybridization to published demonstrated that new China isolate is variant of Heliothis virescens 3a (HvAV-3a), thus named HvAV-3h. We investigated phylogenetic position, cell infection, vesicle production viral DNA replication kinetics HvAV-3h, as well its host-ranges. The major capsid protein...

Abstract Ascoviruses are insect-specific large DNA viruses that mainly infect noctuid larvae, and transmitted by parasitoids in the fields. Heliothis virescens ascovirus 3h (HvAV-3h) has been recently isolated from Spodoptera exigua , without parasitoid vector identified previously. Here we report Microplitis similis a solitary endoparasitoid wasp, could transmit HvAV-3h between S. larvae laboratory. When female wasp acquired virus served as vector, period of virion viability on ovipositor...

Abstract The family Bombycidae (sensu Minet, 1994) is a diverse group of species belonging to the superfamily Bombycoidea. It an economically important moth species, containing well‐known silk‐producing insects, as well many pests agriculture and forestry. morphology‐based hypothesis Minet (1994) on composition in conflict with subsequent phylogenetic hypotheses for based nuclear genes. In this paper, complete mitochondrial genomes nine are presented first time. Based these genomes, four...

Ascoviruses are double-stranded DNA viruses that pathogenic to lepidopteran hosts, particularly noctuid larvae. Infection of a larva is characterized by retarded growth, reduced feeding and yellowish body color. In this paper, we reported the growth development three major agricultural insect pests, Helicoverpa armigera (Hübner), Spodoptera exigua (Hübner) litura (Fabricius), infected with Heliothis virescens ascovirus 3h (HvAV-3h). Using 10-fold serial dilutions (0 7) HvAV-3h-containing...

The current study investigated the impacts of temperature on development and reproductivity sweet potato leaf folder, Brachmia macroscopa (Lepidoptera: Gelechiidae), in leaves under laboratory conditions. We determined developmental time B. larval, pupal, pre-adult stage at different temperatures. Male female longevity, male lifespan, mortality immature stages, oviposition period were also six constant temperatures (21°C, 24°C, 27°C, 30°C, 33°C, 36°C), based age-stage, two-sex life tables....

Abstract Heliothis virescens ascovirus 3 h (HvAV-3h), a dsDNA insect virus, belonging to the family Ascoviridae , can infect caterpillars of several Noctuidae species by ovipositing parasitoid wasps. In order provide comprehensive overview interactive responses host larvae after infection ascovirus, transcriptome analysis Spodoptera exigua HvAV-3h was conducted from 6 168 hours post (hpi). Approximately 101.64 Gb RNA sequencing (RNA-seq) data obtained infected and uninfected S. were used...

Plants respond to herbivorous insect attacks by releasing volatiles that directly harm the herbivore or indirectly attracting its natural enemies. Although larvae of Spodoptera litura (the tobacco cutworm) are known induce release host plant volatiles, effects such on location S. and parasitoid Microplitis similis, a enemy larvae, poorly understood. Here, we found both regurgitate litura-infested cabbage leaves attracted M. similis. had reduced preference for plants been infested with 24 48...

Gene families, which are parts of a genome's information storage hierarchy, play significant role in the development and diversity multicellular organisms. Several studies have focused on characteristics gene such as function, homology, or phenotype. However, statistical correlation analyses distribution family members genome yet to be conducted. Here, novel framework incorporating analysis selection based NMF-ReliefF is reported. Specifically, proposed method starts by obtaining families...

Microplitis similis Lyle (Hymenoptera: Braconidae) is a solitary endoparasitic braconid that generally parasitizes larvae of Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae) and many other noctuid species. To understand host preference, fitness, the effects M. on hosts, we compared percentage parasitism, development periods, growth in candidate We found high levels parasitism S. litura (F.) but not Helicoverpa armigera larvae. The parasitoid wasp took similar amounts time for larvae,...
