New species and new records of Xylosandrus Reitter, 1913 (Coleoptera: Curculionidae: Scolytinae: Xyleborini) from China.

Two new species of ambrosia beetles Xylosandrus Reitter, 1913 (Scolytinae: Xyleborini), Xylosandrus luokengensis Lin & Gao sp. nov. and Xylosandrus nanlingensis Lin & Gao sp.

RNAi-mediated pest control targeting the Troponin I (wupA) gene in sweet potato weevil, Cylas formicarius.

The sweet potato weevil (Cylas formicarius) is a critical pest producing enormous global losses in sweet potato crops. Traditional pest management approaches for sweet potato weevil, primarily using chemical pesticides, causes pollution, food safety issues, and harming natural enemies. While RNA interference (RNAi) is a promising environmentally friendly approach to pest control, its efficacy in controlling the sweet potato weevil has not been extensively studied.

Nitrite accumulation performance and microbial community of Algal-Bacterial symbiotic system constructed by Chlorella sp. And Navicula sp.

Chlorella sp. and Navicula sp. were separately used to construct an algal-bacterial symbiotic system in two identical sequencing batch reactors (R and R) to explore the influence of algal species differences on nitrite accumulation.

Complete mitochondrial genome of Lefèvre, 1893 (coleoptera: chrysomelidae: eumolpinae), a tea pest from Southern China.

The tea pest, Lefèvre 1893 (Chrysomelidae), belongs to the subfamily Eumolpinae. In this study, the complete mitochondrial genome sequence of from southern China was sequenced using the next-generation sequencing technique, assembled, and annotated using bioinformatics tools. The complete mitochondrial genome was 15,905 bp in length.

HCN-induced embryo arrest: passion fruit as an ecological trap for fruit flies.

Background: Fruit flies are important economic pests of fruits, vegetables, and nuts all over the world. In this study, a permanent ecological trap, which was created by the ovicidal effect of phytogenic hydrogen cyanide (HCN) liberated from passion fruits due to oviposition by fruit flies and can be used in the pest management, were determined.

Results: Observation of fruit fly eggs in Passiflora within the passion fruit cultivation region in southern China, from Aug 2019 to Oct 2020 showed that the exotic Passiflora attracted the native fruit flies to oviposit, but the eggs could not hatch.

as a dead-end trap for adult : A potential biological tactic for protecting citrus orchards.

The Asian citrus psyllid, Kuwayama (Hemiptera: Liviidae), is a key vector of the causal agents of Huanglongbing (HLB), a devastating disease affecting citrus almost worldwide. L. is an important commercial crop in China.

The complete mitochondria genome sequence of Moore.

(Moore) is the most destructive defoliating pests in (Loureiro) Sprenger forests in Southern China. The complete sequences of mitochondria is reported: a circular molecule of 15,516 bp in size included 40.13% for A, 40.

Sexual dimorphism in antennal morphology and sensilla ultrastructure of a pupal endoparasitoid Tetrastichus howardi (Olliff) (Hymenoptera: Eulophidae).

Tetrastichus howardi (Olliff) (Hymenoptera: Eulophidae), a pupal parasitoid of a great number of Lepidoptera pests, has a great potential for biological control. To investigate the olfactory system of this parasitoid, we examined the morphology and ultrastructure of the antennal sensilla of both male and female T. howardi using scanning and transmission electron microscopic techniques.
