Abstract Viral diseases have been studied in-depth for reducing quality, yield, health and longevity of the fruit, to highlight the economic losses. Positive-sense single-stranded RNA viruses are more devastating among all viruses that infect fruit trees. One of the best examples is papaya ringspot virus (PRSV). It belongs to the genus Potyvirus and it is limited to cause diseases on the family Chenopodiaceae, Cucurbitaceae and Caricaceae. This virus has a serious threat to the production of papaya, which is famous for its high nutritional and pharmaceutical values. The plant parts such as leaves, latex, seeds, fruits, bark, peel and roots may… More >

Abstract Pecan Carya illinoinensis (Wang.) K. Koch is one of the most important crops in northern Mexico. In the Comarca Lagunera, during 2013, the pecan acre age was 7075 ha, a nut production of 8648 ton, and a value of US$ 29.9 million (US$ 4230/ha). The aphids Monellia caryella Fitch., Monelliopsis pecanis Bissell and Melanocallis caryaefoliae Davis (Hemiptera: Aphididae) are among the most important insect pests associated with the pecan. The objectives of this study were to identify the species of aphids, determine their population dynamics and parasitism, in pecan orchards with different insect pest management programs, in the Comarca Lagunera.… More >
