Benzylchlorocarbene: UV Absorption Spectrum, Kinetics for 1,2-H Migration and Mechanism for Reaction With Acetic Acid as Determined by Combined Continuous and Laser-Flash Photolysis

Publikováno v: Laser Chemistry. 10:267-275
The UV absorption spectrum of benzylchlorocarbene, generated by laser flash photolysis of 3-chloro-3- benzyldiazirine, has been observed in the 290-330 nm range. The lifetime of this species, 18 ns at 25°C, is determined by the rate of the 1,2-H mig

Isolation and structure determination
Autor: P. E. Howse, I. D. R. Stevens, O. T. Jones
Publikováno v: Insect Pheromones and their Use in Pest Management ISBN: 9780412444104
Before starting on any attempt to isolate an insect pheromone, it is important to demonstrate that such a chemical cue is actually involved and also to define the behaviour that is associated with its production and release. Examples of behaviour mig

Factors controlling responses of insects to pheromones
Autor: P. E. Howse, I. D. R. Stevens, O. T. Jones
Publikováno v: Insect Pheromones and their Use in Pest Management ISBN: 9780412444104
This chapter will concentrate on the factors affecting the emitter and receiver of a pheromonal signal. Chapter 1 showed that the interpretation of the signal (i.e. for all practical purposes the response) depends on the context and internal state of

Lure and kill
Autor: P. E. Howse, I. D. R. Stevens, O. T. Jones
Publikováno v: Insect Pheromones and their Use in Pest Management ISBN: 9780412444104
The last chapter discussed the use of semiochemical-based traps for population control through mass trapping. This theme will now be continued but ‘lure and kill’ techniques differ in one respect: the insect, once attracted by the semiochemical l

The role of pheromones in insect behaviour and ecology
Autor: I. D. R. Stevens, P. E. Howse, O. T. Jones
Publikováno v: Insect Pheromones and their Use in Pest Management ISBN: 9780412444104
Primer pheromones may act upon sexual maturation of adult insects (as in the honey bee, Chapter 1) or on development. In locusts both kinds of effect occur. At low densities the desert locust, Schistocerca gregaria, is cryptically coloured, but in hi

Other uses of semiochemicals
Autor: O. T. Jones, I. D. R. Stevens, P. E. Howse
Publikováno v: Insect Pheromones and their Use in Pest Management ISBN: 9780412444104
As the chemical ecology of insect pests slowly becomes unravelled, new opportunities have arisen to exploit semiochemicals in different ways in order to achieve the goal of managing insect pest problems. The semiochemicals used often differ substanti
