Citrus leprosis virus C (CiLV-C) causes a severe disease affecting citrus orchards in the Western hemisphere. This study reveals the molecular variability of the virus by analyzing four genomic regions (p29, p15, MP and RNA2-intergenic region) distributed over its two RNAs. Nucleotide diversity (π) values were relatively low but statistically different over the analyzed genes and subpopulations...

The Chinese citrus fruit fly, Bactrocera (Tetradacus) minax (Enderlein), is one of the major citrus pests in Bhutan and can cause >50% mandarin (Citrus reticulata Blanco) fruit drop. As part of the development of a management strategy for the fly in mandarin orchards, population monitoring and experimental manipulations were carried out to determine: (i) adult emergence period; (ii) adult pheno...

Pasteuria penetrans Sayre & Starr parasitizes several nematode species and is considered a promising biocontrol agent of the root-knot nematode, Meloidogyne spp. (1,7). Numerous plant-parasitic nematodes, including Tylenchulus semipenetrans, however, are seldom if ever infected by this biocontrol agent (3). Tylenchulus semipenetrans Cobb is the most economically important and widespread nematod...

Citrus tristeza is one of the most destructive diseases of citrus and its causing agent CTV was introduced from Japan to northern Iran in the late 1960s. After about three decades of restriction to originally infected Satsuma trees, natural spread of CTV has being undertaken and melon aphid (Aphis gossypii Glov.) was confirmed as a potent vector in these areas. Regarding the specificity of aphi...

The use of synthetic acaricides for management of pest mites may alter the efficacy of the ectoparasitoid Tamarixia radiata (Waterston) in biological control of Diaphorina citri Kuwayama, the vector of the bacteria associated with huanglongbing (HLB) in citrus orchards. We evaluated the toxicity of 16 acaricides that are recommended for the control of citrus-pest mites to T. radiata. Acrinathri...

The African citrus psyllid, Trioza erytreae (Del Guercio) (Hemiptera, Triozidae), is native to tropical Africa and invasive species in North America Europe. main host plants are citrus, displaying a preference for lemon trees. This psyllid was recently detected the northwest region of Iberian Peninsula, both Spain Portugal. Here, we used model combining reaction-diffusion stochastic long-distan...

Conyza species are considered one of the most aggressive weeds in Aegean and Mediterranean regions Turkey terms their invasive character ability to spread agricultural nonagricultural areas, including citrus orchards vineyards. This study was conducted determine distribution vineyards these efficacy glyphosate when used at different growth stages. The majority fields nearly half vineyard were v...

Darjeeling mandarin (Citrus reticulata Blanco) is one of the most popular fruit crops and Kalimpong districts West Bengal, India. The cultivation crop significantly affected by attack Chinese citrus fly Bactrocera (Tetradacus) minax (Enderlein) (Diptera: Tephritidae). Survey was conducted in months November December 2017 2018 to find out dimension problem along with its distribution, detection ...
