Book Description
Excerpt from The Serphoid and Chalcidoid Parasites of the Hessian Fly Because Of the important influence which they exercise in its con trol, the hymenopterous parasites of this pest early became a matter Of interest to entomologists and have become increasingly so as the years have gone by. Because Of aroused interest in natural-control methods, the past 2 or 3 decades have witnessed extensive and in tensive studies on the biology Of various hymenopterous parasites Of injurious insects. Workers on the hessian fly have been active in this field, their investigations resulting in the uncovering Of numer ous heretofore unknown parasites attacking the fly and in the ac cumulation Of much information regarding those already known. More than 130 authors and upward Of 200 separate articles involv ing seven different languages make up the present literature dealing with parasites Of this one host. This mass Of literature, scattered through many different journals, bulletins, etc., and involving much synonymy and many changes in names, taken in conjunction with the natural difficulties involved in the identification of these minute insects, has made it extremely difficult for one engaged in a study Of the parasites Of the fly either to determine their identities or to know what has been written about any particular species. A press ing demand has arisen for a coordinated discussion Of information now available regarding the exact identities, synonymy, distribution, etc., Of the various species attacking this fly.
