The black cutworm, Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae), has been considered a major insect pest in China that causes damage to corn at the seeding stage. The present study measured the lethal and sublethal effects of the neonicotinoid insecticide clothianidin on A. ipsilon. Clothianidin, incorporated using an artificial diet, exhibited signs of active toxicity on fourth-instar larvae of A. ipsilon, with a 50%-lethal concentration (LC50) of 27.77 µg/g. Clothianidin at the LC20 and LC40 levels impaired the normal development of A...

The spatial distribution, composition and source of hydrophobic organic compounds (HOCs) including polyaromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and organochlorinated pesticides (OCPs) of the sedimentary microplastics (0.25-5 mm) in Hong Kong were investigated. The concentration of ΣPAHs ranged between 70.8 and 1509 ng g-1 with inter-site differences although the regional difference was insignificant, indicating localised pyrolytic and petrogenic input of PAHs. The concentration of ΣPCBs (13-1083 ng g-1 ) varied with both study sites and regions with higher concentrations obtained in the western waters, possibly due to the input from Pearl River...

Avian leukosis virus subgroup J (ALV-J) was isolated in meat-type breeder chickens for the first time in 1988 in the United Kingdom. Due to the application of an eradication program, there were fewer reports related to myelocytomatosis or ALV-J in China after 2013. However, there was another breakout almost simultaneously in six provinces of China in February 2018. On-site, 15- to 20-week-old broiler breeder chickens showed depression, paralysis and weight loss. Mortality for certain flocks reached 15%. Sick chickens showed numerous yellow-white neoplasms growing in the sternum, rib and lumbar vertebra and had hepatic and renal metastasis...
