Densities of aphids (Aphis gossypii and A. spiraecola) and mummified aphids at different phenological stages of a blueberry crop were estimated for the purpose of developing sampling plans. Our data set comprised 99 samples taken during the period 20

Pest status of leafminers in cider-apples: The case of orchards in Asturias (NW Spain)

Autor: Josep A. Jacas, M. Miñarro

Publikováno v: Crop Protection. 30:1485-1491

Microlepidopterous leafminers are a potential threat to Spanish cider-apple orchards. For pest management purposes it is important 1) to know the species composition, their incidence and their spatial distribution and 2) to have an efficient and accu

BACKGROUND: The within- and between-plant distribution of the tomato leafminer, Tuta absoluta (Meyrick), was investigated in order to define action thresholds based on leaf infestation and to propose enumerative and binomial sequential sampling plans
