BOOK REVIEW AND NOTICES 



Principles of acarology by G. O. Evans, CAB International, Wallingford, xviii + 564 

 pages, £65, hardback. — The ticks and mites are almost as diverse as insects in their 

 habits and lifestyles, being terrestrial, aquatic (salt and fresh water), herbivores 

 (including gall-makers), predators, commensals and parasites. This astonishing variety 

 is excellently presented in this formidable textbook. The book concentrates on the 

 functional morphology of the Acari, constantly comparing and contrasting structure 

 and function across the many different modes of life. The largest chapter is on 

 classification, detailing the many different groups of ticks and also the relationship 

 between the ticks and other arthropods. Mites and ticks are an order of magnitude 

 smaller than insects — for example the holothyrids which are regarded as 'large to 

 very large' have adults ranging from 2 to 7 mm! Nevertheless, many species are of 

 major economic or medical importance — Varroa on honeybees, Lyme disease 

 transmitted by ticks, spider mites on garden plants and crops, chiggers etc — and many 

 have developed intimate relations with insects and other animals. All aspects of the 

 creatures' biology are considered, profusely illustrated and thoroughly referenced.

Insect pollination of crops, 2nd edn by John B. Free, London, Academic 

 Press, 1993, xii + 684 pages, hardback. — After a general introduction to pollinating 

 insects — mainly honeybees, bumblebees and solitary bees — there follows an extensive 

 review of pollination, arranged by plant crop family. 



The larvae of gall midges (Diptera: Cecidomyiidae) by B. M. Mamaev and 

 N. P. Kirvosheina, translated by J. H. Wieffering, edited by J. C. Roskam, Rotterdam, 

 Balkema, 1993, x + 294 pages, £30, hardback. — This is a translation of the original 

 Russian work Lichinki gallits, published in Moscow in 1965. After introductory 

 chapters on biology, comparative morphology, collecting, preservation and study, 

 the major portion of the book is devoted to a systematic outline of gall midge larvae.
