The microbial ecology within the rhizosphere of Tylenchulus semipenetrans-infected Citrus L. trees was examined. Sixty bacterial strains were obtained from roots infected and eggs T. semipenetrans. Among these some agar plates two nematophagous fungi, Dactylellina gephyropaga (Drechsler) Ying Yang & Xing Z. Liu Arthrobotrys conoides Drechsler. Bacterial identified using 16S rDNA, gyrA rpoB gene...

Citrus, as one of the globally important fruit trees, has been an object of interest for understanding genetics and evolutionary process in fruit crops. Meta-analyses of 19 Citrus species, including 4 globally and economically important Citrus sinensis, Citrus clementina, Citrus reticulata, and 1 Citrus relative Poncirus trifoliata, were performed. We observed that codons ending with A- or T- a...

In previous migration studies, the presence of citrus pollen on adult Helicoverpa zea (Boddie), in conjunction with synoptic weather systems and 72-h backtrack trajectories, were used to identify source zones of migrants. However, data are lacking regarding the retention of citrus pollen for 72-h by H. zea adults. We exposed laboratory-reared and feral H. zea adults to citrus blooms for a 12-h ...

Citrus canker caused by Xanthomonas citri subsp. citri (Xcc) is one of the most important bacterial diseases of citrus. Because citrus canker is not found in many countries including European Union and Australia, Xcc is strictly regulated in order to prevent its spread. In this study, the effects of X-irradiation on Xcc growth either in the suspension or on the surface of citrus fruits were inv...

India is one of the leading citrus−producing countries, next to China and Brazil. Despite sizeable production, especially lemons limes, contributes meagerly world’s citrus market. Of various factors responsible for restricted quantum export, canker (Xanthomonas citri pv. citri) serious causes directly impacts appearance fruits. Considering extent damage, present study aimed understand impact Xa...

The two-spotted spider mite, Tetranychus urticae, causes damage to crops grown in northeast Brazil. adoption of biological control methods and curative (plant-based insecticides) is an essential practice for pest management agroecological systems. Therefore, the aim present study was investigate chemical properties, toxicity, ovicidal activity oils (EOs) from Lippia sidoides, Croton rhamnifolio...

The aim of the present work was to study bioactivity lemon, orange, and grapefruit peel essential oils (EOs) obtained from Argentinian plantations on different agronomically important insect fungal species. chemical profile EOs determined by Gas Chromatography-Mass Spectrometry (GC/MS); insecticidal activity studied through contact fumigant assays; antifungal evaluated with tests. Orange EO mos...

Citrus spp. are spread mainly in the Mediterranean basin and represent largest fruit source for human consumption. Postharvest losses, due to diseases metabolic disorders of fruits, can cause severe wastage, reaching 30 50% total production. Preserving quality extending shelf life essential objectives postharvest technological innovation, determined by proper handling, treatment, storage transp...

Citrus peels, the waste by-products of citrus juices factories are reckoned valuable healthful functional food. The present investigation performed to assess nutritional status of wheat and fortified biscuits with citrus peels powders. Study included determination of gross chemical composition, caloric value , minerals (Fe, Mn, Cu, Ca, Mg, Na, K and P) of wheat and fortified biscuits with citru...
