Bemisia tabaci MED has been an important pest insect in tobacco production in China in recent years. To understand the resistance of different tobacco cultivars to B. tabaci MED, we compared the performance of whiteflies on seedlings of 6 widely cultivated tobacco cultivars by using clip-cages in this study. The results showed that longevity, fecun...

Cigar tobacco (Nicotiana tabacum L.) is an important cash crop in China. Due to suitable ecological conditions, Hainan province is a major area for growing cigar tobacco. Cigar tobacco leaves are both an important source of fiscal taxation and also the main source of income for farmers in Hainan province. In 2018 and 2019, necrotic leaf spots were...

The purpose of this study was to determine the effects of pre-harvest application concentration, frequency, and timing of harpin β protein on improving quality attributes (fruit firmness (FF), size, skin color, soluble solids content (SSC), and titratable acidity (TA)), susceptibility to physiological postharvest disorders (stem browning, surface p...

To clarify the relationships of Pedesta submacula (Leech, 1890), P. submacula rubella (Devyatkin, 1996) and P. similissima (Devyatkin, 2002), specimens from various localities in China and Vietnam, including the type materials of P. submacula rubella and P. similissima were examined. A neighbor-joining (NJ) tree was also reconstructed based upon pa...

It has been reported that squash leaf curl China virus (SLCCNV) infects some Cucurbitaceae crops except for melon (Cucumis melo L.). A new disease of melon exhibiting severe leaf curl and dwarfing was observed in Hainan Province of China. In this study, the pathogen was identified as SLCCNV through biological and molecular characterization. The iso...

A new species of the genus Pedesta Hemming, 1934, viz. P. wangi sp. nov., is described as new to science from northwestern Guangxi, southern China. Based upon 455 bp partial COI sequences, a neighbor-joining (NJ) tree including the new species and twelve congeneric species is reconstructed. It shows that P. wangi sp. nov. is a cryptic species of P....

Based upon the comparison of the 649 bp COI gene sequences, Hasora mavis Evans, 1934 is proved to be the female of a sexually dimorphic species, H. leucospila leucospila (Mabille, 1891), and thus treated as a junior subjective synonym of the latter.

We report here an environmentally benign and facile approach for the synthesis of gold-silver alloy nanoparticles. This approach involves the co-reduction of HAuCl 4 and AgNO 3 by employing Lysimachia christinae polysaccharide as both reductant and stabilizer without the introduction of any other surfactant. The formed gold-silver alloy nanoparticl...

This study aimed to evaluate whether preharvest or postharvest application of glycine betaine (GB) has the potential to improve fruit quality [fruit firmness (FF), size, skin color, soluble solids content (SSC), and titratable acidity (TA)] and susceptibility to storage disorders (peduncle browning, pitting, and decay) in ‘Lapins’ or ‘Regina’ sweet...
