Lime [Citrus aurantifolia (Cristm.) Swingle] is a Citrus species that is a popular ingredient in many cuisines. Some citrus plants are known to originate in the area ranging from northeastern India to southwestern China. In the current study, we characterized and compared limes grown in Bhutan (n = 5 accessions) and Indonesia (n = 3 accessions). The limes were separated into two groups based on...

The spatial distribution of the three principal species of sharpshooter (Dilobopterus costalimai Young, Acrogonia sp. e Oncometopia facialis Signoret), vectors of Xylella fastidiosa causal agent of Citrus Variegated Chlorosis, was studied by using geostatistics. The evaluations were carried out in a commercial ‘Pera’ sweet orange (Citrus sinensis [L.] Osb.) grove budded on Rangpur lime (Citrus ...

Phyllocnistis citrella Stainton, the citrus-leafminer, is an important pest of citrus worldwide. Knowledge of natural parasitism levels is fundamental to the establishment of tactics of management and control of this species. This work aimed to evaluate the parasitism in two citrus orchards, one of ‘Montenegrina’ (Citrus deliciosa Ten.) and the other of ‘Murcott’ (C. sinensis (L.) Osbeck x C. r...

Citrus canker, caused by the bacterium Xanthomonas citri subsp. citri (Xcc), is a severe disease of citrus. Xcc presents broad spectrum of citrus hosts including economically important species whereas X. fuscans subsp. aurantifolii-type C (XauC) causes a milder disease and only infects Citrus aurantifolia. Trehalase catalyzes hydrolysis of the disaccharide trehalose, a sugar that has been repor...

The environmental problems caused by chemical peeling of citrus, together with the establishment of new applications for enzymatic preparations with degradative activities led several investigators to study enzymatic peeling as an alternative to traditional chemical peeling. The principle of enzymatic peeling is based on the digestion, through an enzymatic preparation, of the pectic substances ...

Efficacy of essential oils extracted from peel of various citrus species; Citrus reticulata, Citrus sinensis, Citrus paradisi and Citrus grandis were determined against the adults of Callosobruchus chinensis and Tribolium castaneum as well as against the larvae of Trogoderma granarium in order to find out safe alternatives of high toxics. Four concentrations of each oil; 2%, 4%, 6% and 8% were ...

Citrus is the first tree crop in terms of fruit production. The colour of Citrus fruit is one of the main quality attributes, caused by the accumulation of carotenoids and their derivative C30 apocarotenoids, mainly β-citraurin (3-hydroxy-β-apo-8'-carotenal), which provide an attractive orange-reddish tint to the peel of oranges and Mandarins. Though carotenoid biosynthesis and its regulation h...

Genome wide selection (GWS) is essential for the genetic improvement of perennial species such as Citrus because of its ability to increase gain per unit time and to enable the efficient selection of characteristics with low heritability. This study assessed GWS efficiency in a population of Citrus and compared it with selection based on phenotypic data. A total of 180 individual trees from a c...

Citrus represents one of the most widely grown crops on planet, extensively cultivated for both fresh fruit and juice markets. The productivity citrus orchards can be seriously affected by highly aggressive pathogenic bacteria, such as Xanthomonas citri subsp. citri, Xylella fastidiosa pauca currently Candidatus Liberibacter asiaticus. Different microbiological biocontrol agents have been descr...

in the study of natural enemies of mealybugs (hem.: pseudococcidae) in fars province, iran, a large number of parasitized mealybugs were collected, and the emerged encyrtid species identified as leptomastidea alleni noyes & hayat, 1994. the identification was confirmed by zhihong xu, institute of applied entomology, zhejiang university of china. the genus and species is a new record for iran. t...
