Review of the genus Novius Mulsant (Coleoptera: Coccinellidae) from China with description of four new species.

N/A.

A new species of the genus Blackburn (Coleoptera, Coccinellidae) from China, with description of the immature stages.

A new species Huang & Wang, is described from Yunnan Province, China, as a newly discovered predator on Gennadius (Hemiptera, Sternorrhyncha, Aleyrodidae). The new species is a valuable addition to the 14 species of this genus in China known before. A diagnosis, detailed description, including the structure of its immature stages, illustrations, and the distribution of the new species are provided.

Distribution and accumulation of Cadmium in different trophic levels affecting Serangium japonicum, the predatory beetle of whitefly Bemisia tabaci, biologically, physiologically and genetically: An experimental study.

Cadmium (Cd) is a heavy metal that is of great concern in agroecosystems due to its toxicity to plants, herbivores, carnivores, and human beings. The current study evaluated the allocation and bioaccumulation of Cd from soil to cotton plants, cotton plants to herbivore pests, and herbivorous pests to a natural enemy predator. When soil was spiked with 100 mg/kg Cd, results demonstrated that cotton roots accumulated more Cd than the stems and leaves.

Rosamultin Attenuates Acute Hypobaric Hypoxia-Induced Bone Injuries by Regulation of Sclerostin and Its Downstream Signals.

Wang, Xing-Min, Hui Liu, Jian-Yu Li, Jin-Xia Wei, Xia Li, Yong-Liang Zhang, Ling-Zhi Li, and Xi-Zheng Zhang. Rosamultin attenuates acute hypobaric hypoxia-induced bone injuries by regulation of sclerostin and its downstream signals. 21:273-286, 2020.

Antagonistic interaction between male-killing and cytoplasmic incompatibility induced by Cardinium and Wolbachia in the whitefly, Bemisia tabaci.

Cardinium and Wolbachia are maternally inherited bacterial symbionts of arthropods that can manipulate host reproduction by increasing the fitness of infected females. Here, we report that Cardinium and Wolbachia coinfection induced male-killing and cytoplasmic incompatibility (CI) when they coexisted in a cryptic species of whitefly, Bemisia tabaci Asia II7. Cardinium and Wolbachia symbionts were either singly or simultaneously localized in the bacteriocytes placed in the abdomen of B.

Compatibility and Efficacy of the Parasitoid and the Entomopathogenic Fungus for Biological Control of Whitefly .

Biological control is an effective method for whitefly management compared to the potential problems caused by chemical control, including environmental pollution and the development of resistance. Combined use of insect parasitoids and entomopathogenic fungi has shown high efficiency in control. Here, we assessed the impacts of an entomopathogenic fungus, on the parasitism rate of a dominant whitefly parasitoid, , and for the first time also compared their separate and combined potential in the suppression of under semi-field conditions.

RNAi knock-down of the Bemisia tabaci Toll gene (BtToll) increases mortality after challenge with destruxin A.

Bemisia tabaci (Gennadius) Middle East-Asia Minor 1 (MEAM1) is a well known invasive insect species. Little information is available on immune system of B. tabaci to date.

Toxicological and biochemical basis of synergism between the entomopathogenic fungus Lecanicillium muscarium and the insecticide matrine against Bemisia tabaci (Gennadius).

The sweetpotato whitefly Bemisia tabaci (Gennadius) was challenged with different combinations of matrine (insecticide) and Lecanicillium muscarium (entomopathogenic fungus). Our results revealed a synergistic relationship between matrine and L. muscarium on mortality and enzyme activities of B.

Plantmediated horizontal transmission of Wolbachia between whiteflies.

Maternal transmission is the main transmission pathway of facultative bacterial endosymbionts, but phylogenetically distant insect hosts harbor closely related endosymbionts, suggesting that horizontal transmission occurs in nature. Here we report the first case of plant-mediated horizontal transmission of Wolbachia between infected and uninfected Bemisia tabaci AsiaII7 whiteflies. After infected whiteflies fed on cotton leaves, Wolbachia was visualized, both in the phloem vessels and in some novel 'reservoir' spherules along the phloem by fluorescence in situ hybridization using Wolbachia-specific 16S rRNA probes and transmission electron microscopy.

De novo sequencing-based transcriptome and digital gene expression analysis reveals insecticide resistance-relevant genes in Propylaea japonica (Thunberg) (Coleoptea: Coccinellidae).

The ladybird Propylaea japonica (Thunberg) is one of most important natural enemies of aphids in China. This species is threatened by the extensive use of insecticides but genomics-based information on the molecular mechanisms underlying insecticide resistance is limited. Hence, we analyzed the transcriptome and expression profile data of P.

The genus Shirozuella Sasaji (Coleoptera, Coccinellidae, Shirozuellini) from the Chinese mainland.

The genus Shirozuella Sasaji, 1967 from the Chinese mainland is reviewed. Eight species are recognized, including four new species: Shirozuella motuoensissp. n.

A review of the genus Serangium Blackburn (Coleoptera, Coccinellidae) from China.

The genus Serangium Blackburn from China is reviewed. The genus Catanella Miyatake is removed from synonymy with Serangium. Serangium baculum Xiao is transferred to Catanella, as Catanella baculum (Xiao), comb.

[Development and reproduction of B-biotype Bemisia tabaci on four cucurbitaceous host plants].

The study on the development and reproduction of B-biotype Bemisia tabaci on four cucurbitaceous host plants, i. e., cucumber, hairy gourd, bitter cucumber, and sponge gourd, showed that the one generation development duration of B.

[Effects of different concentration ammonium-n on Hydrilla verticillata antioxidant enzymes under Cd stress].

In this paper, submersed plant Hydrilla verticillata was cultivated in a 1/10 Hoagland culture medium added with different concentration NH4 + -N (0, 0. 5, 2. 0, 4.

[Effects of both single and combined pollution of Cd and Nh4+ on Hydrilla verticillata and Myriophyllum spicatum].

Combined pollution is more ubiquitous than the single pollution in water and soil environment. Iodine method was used to study the effects of both single and combined pollution of Cd and NH4+ on Hydrilla verticillata and Myriophyllurn spicatum. Results came out that H.

[Study on the fluorescence spectra of LaL3 with DNA].

A fluorescence method is presented for the determination of DNA. The method is based on the interaction of LaL3 [L = morin (2', 3, 4', 5, 7-Pentahydroxyflavone), 2'-OH group deprotonated] with DNA in NH3 x H2O-NH4Cl buffer of pH = 8.0, with lambdaex at 387 nm, and lambdaem at 535 nm.
