Effector enrichment by Candidatus Liberibacter promotes Diaphorina citri feeding via Jasmonic acid pathway suppression.

Background: Citrus huanglongbing (HLB) is a devastating disease caused by Candidatus Liberibacter asiaticus (CLas) that affects the citrus industry. In nature, CLas relies primarily on Diaphorina citri Kuwayama as its vector for dissemination. After D.

First Record of as an Entomopathogenic Fungus against Asian Citrus Psyllid, Kuwayama (Hemiptera: Liviidae).

The Asian citrus psyllid Kuwayama (Hemiptera: Liviidae) is the most widespread and devastating pest species in citrus orchards and is the natural vector of the phloem-limited bacterium that causes Huanglongbing (HLB) disease. Thus, reducing the population of is an important means to prevent the spread of HLB disease. Due to the long-term use of chemical control, biological control has become the most promising strategy.

Adaptability and 'Candidatus Liberibacter asiaticus' titres of Diaphorina citri adults on three weed species in China.

Background: Diaphorina citri is a vector of 'Candidatus Liberibacter asiaticus' (CLas), which is associated with citrus huanglongbing (HLB). In this study, the adaptability and CLas titres of D. citri adults on three weed species, namely, Ageratum conyzoides, Solanum nigrum and Praxelis clematidea, which are widely distributed in citrus orchards in China, were determined.

Phytoseiid mites (Acari: Mesostigmata: Phytoseiidae) in Nanling National Nature Reserve, Guangdong, China.

Nanling National Nature Reserve is the biggest natural reserve in Guangdong Province. It is located on the south side of the Nanling middle mountain range, bordering on Hunan Province. During Oct.

Susceptibility of Selected Tea Shoots to Oviposition by (Hemiptera: Cicadellidae) and Feasibility of Egg Removal with Harvesting.

The (Hemiptera: Cicadellidae) female lays its eggs inside the epidermis of the tea plant shoots. This has led to speculation that shoot harvesting could represent a method of egg removal. To verify the validity of this hypothesis, we sought to determine which part of the shoot was used for the oviposition and how the value of the harvested shoot affects the cost of the egg removal.

The preference choices of Conopomorpha sinensis Bradley (Lepidoptera: Gracilariidae) for litchi based on its host surface characteristics and volatiles.

Conopomorpha sinensis Bradley is a host-specific pest of Litchi chinensis and Euphoria longan. Here, we demonstrated that C. sinensis has evolved special physical and chemical mechanisms for host plant location that enable it to survive and reproduce.

The isolation and identification of pathogenic fungi from Drury (Hemiptera: Tessaratomidae).

Background: Litchi stink-bug, Tessaratoma papillosa Drury (Hemiptera: Tessaratomidae), is one of the most widespread and destructive pest species on Sonn and Lour in Southern China. Inappropriate use of chemical pesticides has resulted in serious environmental problems and food pollution. Generating an improved Integrated Pest Management (IPM) strategy for litchi stink-bug in orchard farming requires development of an effective biological control agent.

Interspecific Competition Between Ceratitis capitata and Two Bactrocera Spp. (Diptera: Tephritidae) Evaluated via Adult Behavioral Interference Under Laboratory Conditions.

The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), is considered one of the most invasive tephritid species. It has spread and established populations successfully throughout many of the tropical temperate regions, partially owing to the increase in global trading activity that facilitates diffusion of species. However, C.

[Ecological control effects of Litchi chinensis-Desmodium intortum complex plant ecosystem on litchi pests].

An investigation on the community structure and dynamics of litchi pests and their natural enemies in constructed Litchi chinensis-Desmodium intortum complex plant ecosystem and single L. chinensis ecosystem showed that the total amount of litchi pests in the complex plant ecosystem was 61.27% of that in the single ecosystem in whole year, and only 50.

[Contributing factors and control strategies of pine wilt disease].

There are several types of pine wilt diseases with inherent inter-relations. The diseases are closely related with the complex ecological system composed of local environment, pine trees, insect vectors, and pathogenic nematodes and some other microorganisms. Sustainable pest management based on ecology is a potential approach for pine wilt disease control.
