Ground penetrating radar has come to public attention in recent criminal investigations, but has been a developing and maturing remote sensing field for some time. In the light of recent grow.h of the technique to a w.de range of applications, the need for an up-to-date reference text has become pressing. This fully revised and expanded edition of david Daniels''bestselling text, Surface-Penetrating Radar (IEE, 1996) presents, for the non-specialist user or engineer, all the key elements of this technique, w.ich span several disciplines including electromagnetics, geophysics and signal processing. The book enables the user to assess the potential of the technique and apply it effectively w.th current *** new.edition is a greatly expanded treatment of a radar technique that penetrates the surface of the ground or man-made structures and contains many additional contributions by leading experts in the field. Ground penetrating radar is increasingly used to examine archaeological sites, engineering structures (e.g. bridges, roads) etc., and has come to some prominence in forensic investigations. GPR is also used for the detection of landmines. The book presents the principles w.th an emphasis on practical applications and also includes a CD w.th many examples of GPR data and processing techniques as Mathcad w.rksheets.

The potato psyllid, Baetericera （= Paratrioza） cockerelli （gulc）（Hemiptera： Triozidae）, is a maj.r pest of potato. Studies w.re conducted to determine the age at w.ich both males and females reach reproductive maturity and the effect of age and time of day on sex attraction. Adult B. cockerelli reach reproductive maturity w.thin 48 h post-eclosion, w.th females being mature on the day of eclosion and males at 1 day post-eclosion. Oviposition generally began 2 days after mating but w.s delayed w.en females mated w.thin 2 days post-eclosion. In laboratory olfactometer assays, the age of females used as odor sources and the age of males assayed to these odors did not affect sex attraction, w.th both younger （1-4-day-old） and older （8-10-day-old） males being attracted to females, regardless of female age （1-4-day-old or 8-10-day-old）. Males assayed to live females at different times during the photophase （betw.en 8：00 and 20：00 hours） w.re attracted to females betw.en 11：00 and 17：00 hours, show.ng a temporal periodicity in sex attraction w.th B. cockerelli at least during the photophase.
