Three new species of Hyadaphis Kirkaldy, 1904 (Hemiptera, Aphididae, Macrosiphini) are established: Hyadaphis levantina sp. n. from specimens caught on Lonicera nummulariifolia from Lebanon and Israel, and Hyadaphis anethi sp. n. plus Hyadaphis parva sp. n. from specimens respectively caught on Anethum sp. and Andrachne (?) cordifolia from Pakistan. Apterous viviparous females of all three species, alate viviparae of the first two and males of H. anethi are described. Known and new species of Hyadaphis are grouped for two relevant characters: (1) size and shape of siphunculi, and (2) host plant and life cycle; and the discriminant features of apterous viviparous females of the new species are compared with the already described species of the same group and a key for the Hyadaphis species is provided.

Hyadaphis foeniculi (Passerini) (Hemiptera: Aphididae) is a cosmopolitan species and the main pest of fennel in northeastern Brazil. Understanding the relationship between temperature variations and the population growth rates of H. foeniculi is essential to predict the population dynamics of this aphid in the fennel crop.

The fennel aphid, Hyadaphis foeniculi (Passerini) (Hemiptera: Aphididae) is a major pest of fennel, Foeniculum vulgare Miller in northeast region of Brazil. We hypothesize that intercropping can be used as an alternative pest management strategy to reduce aphid yield loss in fennel. Thus, we investigated the severity of fennel plant damage in relation to infestation by the fennel aphid and predation by Cycloneda sanguinea (L.

This research sought to identify the aphid virus vector species associated with lettuce and broccoli crops in Spain, and to determine their population dynamics and ability to transmit Lettuce mosaic virus (LMV). Green tile traps and Moericke yellow water-pan traps were used to monitor aphid flights during the spring and autumn growing seasons of 2001. Aphid species feeding on lettuce were counted weekly.
