Citrus Huanglongbing (HLB) is one of the most destructive diseases of citrus worldwide and is threatening the survival of the Floridian citrus industry. Currently, there is no established cure for this century-old and emerging disease. As a possible control strategy for citrus HLB, therapeutic compounds were screened using a propagation test system with 'Candidatus Liberibacter asiaticus'-infec...

Background Dengue fever is a serious public health issue in Pakistan for many years. Globally plants have been reported to contain compounds with insecticidal properties. These properties have been demonstrated more recently on the larval stages of mosquitoes. Therefore, Citrus cultivar seeds were evaluated for larvicidal potential against the primary dengue vector Aedes aegypti. Methods Extr...

Mentha piperita and Citrus sinensis was an aromatic plants well known for its fragrance and distinct aroma. In this prospective study to evaluate the chromatogram detection of ethanol extract of Mentha piperita and Citrus sinensis with standard flavonoid marker eriocitrin by HPTLC technique. HPTLC chromatogram was developed in ethanolic extract of Mentha piperita, Citrus sinensis and standard f...

Six Alabama Satsuma mandarin orchards (four conventionally sprayed and two unsprayed) were surveyed during 2005 and 2006 to determine the population dynamics of arthropod pests and their natural enemies. Twenty-eight arthropod pest species were encountered; the major foliage pests were citrus whitefly, Dialeurodes citri (Ashmead); purple scale, Lepidosaphes beckii (Newman); Glover scale, L. glo...

BACKGROUND It has been reported that fruit intake protects against cardiovascular disease (CVD). However, most of the relevant studies were conducted in Western countries, and only a few investigated Japanese populations. The present cohort study assessed the effect of citrus fruit intake on the incidence of CVD and its subtypes in a Japanese population. METHODS A baseline examination consist...

Citrus Huanglongbing (HLB), a highly devastating citrus disease, is associated with 'Candidatus Liberibacter asiacitus' (CLas), a member of phloem-inhabiting α-proteobacteria. HLB can affect all cultivated citrus and no cure is currently available. Previous studies showed that Kaffir lime (Citrus hystrix), primarily grown in South Asia and Southeast Asia, was tolerant to HLB but the molecular m...

Citrus genus includes some of the most important cultivated fruit trees worldwide. Despite being extensively studied because of its commercial relevance, the origin of cultivated citrus species and the history of its domestication still remain an open question. Here, we present a phylogenetic analysis of the chloroplast genomes of 34 citrus genotypes which constitutes the most comprehensive and...

background and aims: citrus exocortis disease is naturally limited to citrus plants and causes a serious disease on sensitive rootstocks such as trifoliate orange. the aim of this study was to sample new variants of citrus exocortis viroid from fars trees with yellowing and suberization symptoms and comparison with other isolates of this viroid. materials and methods: a number of symptomatic or...

The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Psyllidae), is one of the most economically destructive pests of citrus worldwide. D. citri vector the phloem-inhabiting bacterium Candidatus Liberibacter asiaticus, which is the presumed causal agent of huanglongbing (HLB) disease in citrus in North America. HLB, otherwise known as citrus greening disease, is the greatest biotic t...

A method of multiplex polymerase chain reaction (PCR) was developed for the simultaneous detection of Citrus yellow mosaic virus (CYMV) and fastidious Citrus greening bacterium, Candidatus Liberibacter asiaticus (CLa) in sweet orange trees. Initially total DNA from individual CLa and CYMV infected citrus plants were mixed and both pathogens were detected simultaneously by multiplex PCR. Subsequ...
