Abstract BACKGROUND: Nucleopolyhedrovirus (SeNPV) and Microplitis pallidipes are important biological control agents of Spodoptera exigua populations. The interactions between these their combined effect on pest were investigated in the laboratory commercial greenhouses. RESULTS: searched for deposited eggs more healthy larvae than virus‐infected 3 days after viral infection. Each female parasitoid that developed a host oviposited host, or emerged from cocoon carrying virus transmitted to...
Abstract Previous studies have shown that the infectivity of baculovirus to herbivores is affected by phytochemicals ingested during acquisition viral inoculum on foliage host plants. Here, we measured effects 14 plant species Spodoptera exigua nucleopolyhedrovirus (Se NPV ) its larvae. The order LD 50 values Se among plants was Ipomoea aquatica > Brassica oleracea Raphanus sativus Amaranthus tricolor Spinacia Vigna unguiculata Solanum melongena Capsicum annuum Apium graveolens Allium...
Many studies have supported the enemies hypothesis, which suggests that natural are more efficient at controlling arthropod pests in polyculture than monoculture agro-ecosystems. However, we do not yet evidence as to whether this hypothesis holds true peach orchards over several geographic locations. In two different areas eastern China (Xinchang a town Shanghai municipality, and Hudai, Jiangsu Province) during continuous three-year (2010–2012) investigation, sampled predators Trifolium...
Abstract It has been reported that the susceptibility of insect herbivores to entomoviruses is affected by phytochemicals ingested during acquisition viral inoculum on foliage host plants. However, relationship between this and poorly understood. To test hypothesis plant‐mediated effects susceptibility, we measured from three plants, soybeans ( Glycine max ), collards Brassica oleracea ) water convolvuluses Ipomoea aquatica larval beet armyworm Spodoptera exigua nucleopolyhedrovirus NPV...
Abstract BACKGROUND Interactions between herbivorous insects and entomoviruses may depend on host plant, perhaps mediated through changes in herbivore innate immunity. RESULTS Caterpillars ( Spodoptera exigua ) fed Glycine max had high viral loads low melanization rates together with enzyme [PO, DDC, TH] activities gene expressions. Ipomoea aquatica melanization, expressions while those Brassica oleracea or artificial diet intermediate levels of each. Melanization were negatively correlated...
Urbanization is a pressing challenge for earth's humans because it changing not only natural environments but also agricultural lands. Yet, the consequences of cropland loss on pest insect populations that largely depend these habitats remain unclear. We used 17-year data set to investigate dynamics three moth species (i.e., striped stem borer, yellow and pink borer) their driving forces across largest mega-urban region China. Total abundance declined by about 80%, which was strongly...
AbstractThe behaviour and oviposition of solitary endoparasitoid Microplitis pallidipes Szepligeti (Hymenoptera: Braconidae) were monitored to investigate the ability parasitoids distinguish between nucleopolyhedrovirus (NPV)-infected noninfected Spodoptera litura Fabricius (Lepidoptera: Noctuidae) larvae. The results indicated that parasitoid searching time until first attack on infected larvae greater than those recorded larvae; number attacked by parasitoids, percent attacks parasitism...
The physiological effects of nucleopolyhedrovirus (NPV) infection and parasitism by Microplitis pallidipes (Hymenoptera: Braconidae) on the hemocytes Spodoptera exigua (Lepidoptera: Noctuidae) larvae were examined. We found that compared to healthy (control) larvae, total hemocyte count (THC) granulocyte in parasitized increased 1 day after parasitization then decreased, while plasmatocyte was not significantly affected for first 5 days but enhanced 6 parasitization. In + infected both THC...
Abstract The use of ground cover vegetation is becoming a prominent way promoting biodiversity and associated ecosystem services in Chinese orchards. Despite the large number studies that have addressed effects on natural enemy populations related pest control, it still unclear whether enhanced control can increase yield reduce pesticide. We performed an experiment comparing three practices (ryegrass, clover hairy vetch) versus bare commercial pear orchards Yangtze River Delta East China...
Abstract BACKGROUND Tri‐trophic interactions among plants, insect herbivores and entomopathogens are one of the hot topics in ecology. Although plants have been shown to impact between entomopathogens, it is still unclear how affect cellular immunity entomopathogens. RESULTS The number hemocytes proportion two main cell types (granular plasmatocytes), plasmatocyte‐spreading rate, apoptosis Spodoptera exigua caspase ( Se Casp‐1, Casp‐5) activities gene expressions were all higher expression...
