Abstract This study simplifies the complex relationship among grapevine plants, aphids, ladybirds, and ants, which is essential for effective pest management and ecological balance. This study investigated the impact of aphid attacks and the presence of ants and ladybirds on the volatile compounds profile released into the chemosphere of the community consisting of the common vine Vitis vinifera, the aphid Aphis illinoisensis, the ladybird Coccinella undecimpunctata-and the ant Tapinoma magnum. This study aims to analyze the volatile compounds emitted by the grapevine and surrounding insects in response to these intricate interactions. The extraction of volatile organic compounds (VOCs) was carried… 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… More >
