We open Volume 7 with a series of four chapters on plant virus transmission by insects. In Chapter 1, Karen Gibb and John Randles present preliminary information about an association between the plant bug Cyrtopeitis nicotianae (Heteroptera: Miridae) and velvet tobacco mottle virus (VTMo V): the only reported instance of mirid transmission of a known virus. Mirids could be considered as likely vectors of plant viruses because they are phytophagous, possess a piercing-sucking-feeding apparatus, have winged adults, and are cosmopolitan pests of a wide range of crops. Surprisingly, however, there are only three plant viruses purportedly transmitted by heteropterous vectors, compared with the nearly 250 by homopterous ones. To what extent these figures reflect actual differences in the abilities of members of the two suborders to transmit plant pathogens remains to be determined. Compared with the Homop tera, the Heteroptera have been ignored by researchers as potential vectors of plant viruses. The authors are quick to point out that additional studies are needed before generalizations can be made about virus-mirid-plant interactions and that virus transmission by mirids is not easily characterized using the conventional transmission criteria and terminology established for such homopterous vectors as aphids and leafhoppers. Transmission of VTMoV by C. nicotianae appears to have characteristics in common with both nonpersistent noncirculative and circulative (persistent) transmission."

3 million college degrees will be awarded this year. For these 3 million students and the millions more that will follow, great challenges await them. They will be challenged in finding a job. They will be challenged in obtaining a job. However, their greatest challenge will be learning how to "succeed" in that job. New employees must learn how to: assimilate into their new role as young professionals, navigate the inner workings of the corporate world, build a favorable image and reputation, create political capital and develop and leverage meaningful contacts. While thousands of books have been written with the aim toward helping someone find work and obtain work; this unique, enlightening and extremely valuable book takes a starkly different approach. "Why Didn't Somebody Tell Me This Stuff?" is written with the sole intent of helping one truly "succeed" in their career. This book is quite simply unlike any other career oriented resource available today.
