Insect Chemical Ecology provides a comprehensive view of how
natural selection acts upon interacting organisms and how
particular physical and biological properties of chemical compounds
act as constraints upon which natural selection may act. Individual
chapters raise specific questions as to the nature of these
interactions. The first part contains reviews on antagonistic and
mutualistic chemical interactions, the raw materials' of chemical
evolution, the economics of offensive and defensive chemicals, and
neurobiology. The second part discusses particular problems such as
the evolution of resistance, insect pollination, learning,
pheromones, sequestration of semiochemicals, the role of
microorganisms, sex attractants, the evolution of host races and
biotypes, and the role of semiochemicals and the evolution of
sociality of insects. The last chapter discusses the role of
chemical-based pest management programs in an ecological and
evolutionary framework.
This volume contains reviews which are based on a symposium, given
th at the 30 meeting of The Phytochemical Society of North America,
held at Laval University in Quebec City, Canada on August 11-15,
1990. During the past two decades, there have been major new
developments in methods which can be applied toward the isolation,
separation and structure determination of complex natural products.
Therefore, the topic of this symposium, "Modem Phytochemical
Methods," is a very timely one. The organizers of the symposium
recognized that it would not be possible to cover in detail all new
advances in phytochemical methodology. It was therefore decided to
emphasize general reviews on recent developments of major
separation techniques such as high performance liquid
chromatography as well as supercritical fluid chromato graphy. In
addition, advances in commonly used structure determination
methods, mainly NMR and MS, are reviewed. Other topics include
methodo logies of micro-sampling for isolation and analysis of
trichome constituents as well as recent breakthroughs on
biosynthetic studies of monoterpenes using "enriched" basal cells
of trichomes. The volume concludes with a review of quantitative
structure-activity relationship (QSAR) studies of biologically
active natural products. In Chapter I, K. Hostettmann and his
colleagues give a general review of recent developments in the
separation of natural products with major emphasis on preparative
separations of biologically active plant constituents. The authors
present a comparison of droplet countercurrent chromatography
(OCCC) with the highly rapid and more versatile centrifugal
partition chromatography (CPC)."
