Quality control and production of biological control agents by J C van Lenteren

By J C van Lenteren

Using organic regulate brokers has been expanding around the world and there at the moment are many businesses mass-producing such organisms, rather for the regulate of insect pests. even though, there's a nice want for qc within the construction and use of those ordinary enemies, which come with insect parasitoids and predators, fungi and viruses. This e-book has been written through major scientists from Europe and North the US to supply either history idea and useful assistance in this subject.

The Social Construction of Science: A Comparative Study of Goal Direction, Research Evolution and Legitimation

This ebook issues the institutionalisation of the actual sciences. The ebook breaks with the demonstrated culture within the heritage, philosophy and sociology of sciences by way of trying to trap either the cognitive and social dimensions of institutionalisation in a single unified research. This unifica­ tion has been accomplished via a remedy of study as objective directed social motion - a subject which has been constructed either theoretically and empirically.

Example text

By analogy, we expect naïve parasitoids foraging for hosts to use stimuli unambiguously associated with oviposition as key stimuli, and not, for example, stimuli associated with finding the host habitat. This is in fact what is observed, for example, in L. heterotoma, which does not link a novel odour to the presence of a substrate, but to the presence of hosts (Vet and Groenewold, 1990). Current knowledge indicates that the key stimuli used by naïve parasitoids in associative learning are always host-derived.

Is of particular interest to those developing quality control methods. Insight into the variability and predictability of naturalenemy behaviour will lead to adequate and realistic tests to evaluate foraging behaviour.
