Parasitoid wasps are rapidly developing as a model for evolutionary biology. Here we present chromosomal genomes of two Anastatus wasps, A. japonicus and fulloi, leverage these to study fundamental questions-genome size evolution venom evolution. shows much larger genome than is known among other with unexpectedly recent bursts LTR retrotransposons. Importantly, several genomic innovations, including Piwi gene family expansion, ubiquitous expression profiles, well transposable element-piRNA...
Abstract Insect pest management is a very important aspect for plant protection in crops production. Remote sensing provides large number of techniques that are beneficial entomological research. Although radars have been used studying migrations insects many years, most radar studies vertically tracing high‐altitude migration behaviour insects. Light detection and ranging (lidar) counterpart to radar, now operating the optical part electromagnetic spectrum, which has recently applied...
Soybean oil is a significant alternative to synthetic chemicals for environmentally friendly and sustainable pest control. This study evaluated soybean its fatty acids (palmitic, oleic, stearic acids; individually) their acaricidal repellent effects against Panonychus citri (Tetranychidae) predators [ Neoseiulus californicus barkeri [Phytoseiidae]) using laboratory foliar dipping topical spray methods. The LC 50 (Lethal Concentration) values palmitic, acids, P. were 0.86%, 0.95%, 0.56%,...

Tetranychus urticae Koch and kanzawai Kishida are important pest mites of various crops economic importance around the world. Prey consumption functional responses two species phytoseiid on these spider were evaluated at 25 ± 1°C, 65 10% RH in artificial climatic chamber with a photoperiod 16 h light:8 dark. The response both Neoseiulus was type II three immature stages (egg, larva protonymph) species. value attack rate coefficients (α) N. californicus to each stage greater than...
Anastatus japonicus Ashmead (Hymenoptera: Eupelmidae) is a solitary egg endoparasitoid that has been studied for inundative biological control of Halyomorpha halys Stål (Hemiptera: Pentatomidae) in China. In this study, we assessed the reproductive attributes and functional response on factitious host, Antheraea pernyi (Guérin-Méneville) (Lepidoptera: Anthelidae) at 25 ± 1 °C, 70 5% relative humidity 16 h:8 h light/dark photoperiod.
The genus Anastatus comprises a large group of parasitoids, including several biological control agents in agricultural and forest systems. taxonomy phylogeny these species remain controversial. In this study, the mitogenome A. fulloi Sheng Wang was sequenced characterized. nearly full-length 15,692 bp, compromising 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA region (CR). total A + T contents were 83.83%, 82.18%, 87.58%, 87.27%, 82.13% whole mitogenome, PCGs, CR, respectively....
Asian corn borer, Ostrinia furnacalis (Guenée), is a key pest in the Asian-Western Pacific countries. It overwinters as full-grown larvae plant stalks or spun-silk covering located debris temperate regions of China. Supercooling point (SCP) and survival rate after low sub-zero temperature treatment were assessed for field-collected populations laboratory using cool bath with 1°C/min cooling until -40°C. Mean SCPs varied among geographical populations, significant decline from -22.7°C Haikou,...
Neoseiulus californicus and N. cucumeris are both potential candidates for the biological control of key pests in China. Whereas has mainly been used to spider mites, released thrips mites. To understand combined use suppress outbreaks Tetranychus urticae, predatory performance these species against different stages T. either separately or combination, was evaluated by assessing their functional responses laboratory. The values attack rate coefficient (α) each stage urticae exceeded those...
RT-qPCR remains a vital approach for molecular biology studies aimed at quantifying gene expression in range of physiological or pathological settings. However, the use appropriate reference genes is essential to attain meaningful results. Anastatus japonicus Ashmead (Hymenoptera: Helicopteridae) an important egg parasitoid wasp and natural enemy fruit bugs forest caterpillars. While recent transcriptomic have analyzed profiles A. specimens, offering robust foundation functional research...
Although the release of egg parasitoids has proven to be an effective strategy for control fall armyworm (FAW), a single parasitoid, however, exposed some deficiencies in practice, and it is worthwhile explore whether combination multiple parasitoid species released can used FAW by adopting inter- or intra-specific relationship. In this study, we compound balls Te. remus Tr. chilonis maize fields effects combinations different proportions these two on FAW. The results showed that improved...
Trissolcus japonicus (Ashmead) (Hymenoptera: Scelionidae) and Anastatus Ashmead Eupelmidae) are the most important egg parasitoids of Halyomorpha halys Stål (Hemiptera: Pentatomidae) in northern China. In this study, we assessed fitness these two parasitoid species at different temperatures. We examined intrinsic competition inside host eggs by providing each with H. masses previously parasitized other species, time intervals between attacks. also investigated their intraguild for releasing...
Background The oriental fruit fly, Bactrocera dorsalis Hendel, causes serious losses to production and is one of the most economically important pests in many countries, including China, Spalangia endius Walker a pupal parasitoid various dipteran hosts, may be considered potentially ectoparasitic B. dorsalis. However, lack genetic information on this organism an obstacle understanding mechanisms behind its interaction with host. Analysis S. transcriptome essential extend resources species...
T. chilonis is a commonly used biological agent, but its existing host eggs have shown some problems in the breeding of chilonis, and search for more suitable imminent. Here, we focused on S. c. ricini, an intermediate that was past Trichogramma spp. has since received less attention. We attempted to understand effects developmental temperature duration longevity egg production, evaluated functional response ricini egg, screened wasp-to-egg ratio production chilonis. Our results showed after...
Trichogramma is a kind of egg parasitoid wasp that widely used to control lepidopterous pests. Temperature one the main factors determines various life activities this species, including development, reproduction and parasitism efficiency. Heat shock proteins (HSPs) are highly conserved ubiquitous best known for their responsiveness temperature other stresses. To explore potential role HSPs in we obtained full-length cDNAs six HSP genes (Tchsp10, Tchsp21.6, Tchsp60, Tchsp70, Tchsc70-3,...
We studied the parasitism capacity of Spalangia endius as a pupal parasite Bactocera dorsalis after switching hosts. used pupae B. and M. domestica hosts by S. in laboratory. The capacities were compared at different host densities parasitoid ages. two functional responses fitted Holling Type II equation. More parasitized than all densities. ability to control was α/Th (parasitism capacity) = 32.1950, which much stronger that dorsalis, 4.7380. rate wasps had decreased emergence time...
Abstract BACKGROUND Anastatus japonicus Ashmead, a biological control agent utilized in China to fruit bugs and forest caterpillars, is efficiently raised on large Chinese oak silkworm ( Antheraea pernyi ) eggs. Here, we investigated the parameters of non‐diapaused diapaused after long‐term storage within eggs host, , under laboratory conditions. RESULTS Diapaused mature larvae were more cold‐tolerant than larvae, as reflected by lower supercoiling point, freezing higher survival rate at...
Anastatus japonicus Ashmead is a widely used biological control agent against stink bugs that can be successfully reared using the large eggs of Chinese silkworm.
