Agromyzidae (Diptera) of Economic Importance by K.A. Spencer

By K.A. Spencer

The unique stimulus which began KENNETH SPENCER on a examine of the Agro­ myzid flies was once a call for participation, which he authorised, to translate from the German the monograph on Leaf Miners by way of Professor E. M. HERING. From this constructed approximately twenty years of collaboration till Professor HERING's dying in 1967. Dr. SPENCER has himself defined over six hundred new species within the kin, a lot of which he accrued and reared from identified host crops in the course of his huge travels to all of the 5 major continents. mostly because of his paintings, the variety of species recognized in Britain has elevated from ninety in 1945 to 313 this present day. he's therefore uniquely certified to jot down this e-book concerning the hundred and fifty or so species that are on a regular basis linked to cultivated vegetation. a lot of the taxonomic element supplied the following could be of worth basically to experts; yet with assistance from a microscope and the botanical host checklist (Chapter 2) and the various illustrations (mostly ready via ANN SPENCER) these in agri­ cultural institutes and in different places should still now be capable of determine the vast majority of species stumbled on attacking vegetation in any a part of the world.
