Codling-moth larvae

Table VII. There was no significant difference between the potency of o-chloro-fluorobenzene and p-bromofluorobenzene toward codling moth larvae, but o-bromo-fluorobenzene and p-chlorofluorobenzene must be tested to determine whether the detectable difference is due to the difference in halogen substitution or to position isomerism.

Baculoviruses are generally named after the insect from which they were first isolated. For example, Cydia pomonella granulovirus (CpGV) was isolated initially from codling moth larvae and Anagrapha falcifera nuclear polyhedrovirus (AfNPV) was isolated from the alfalfa looper. This nomenclature is now widely accepted but it often conceals the number of insects that can be infected and the preferred insect host of the virus. 

The most important enemies of the codling moth are braconid and ichneumon wasps on pupae and fully grown caterpillars. They are not as effective as they are against leaf rollers, however, as the codling moth larva inside the fruit is very well protected against these parasites. 

Young codling moth larvae are highly susceptible to infection by viruses and bacteria. 

Cause Codling moth larvae. These fat, white or pinkish, V " caterpillars tunnel into nuts and may have departed by the time you discover the damage. Nuts may have a hole filled with what looks like moist sawdust. Control codling moths with superior oil or pyrethrin. Late-blooming cultivars, such as Hartley and Vina", are least suscefjtible to codling moths. For more information, see Fruit with holes surrounded by brown, crumbly excrement" on page 22. 

It was with the action of phenothiazine that the importance of particle size was first recognised, in 1939, in relation to its toxicity to codling moth larvae, and in 1940 in relation to its anthelmintic effect, in both of which it was shown that reduction in particle size increased activity. The improvement in biological response to griseofulvin on microni-sation is well known similar blood levels of the dmg were obtained with half the dose of micronised dmg compared to those of non-micronised griseofulvin.

Kairomones are chemical messengers that bring advantageous news to the receiver, and the floral scents are kairomones from the honeybees viewpoint. Many predators are guided by kairomones emitted by their food. For example, apple skins exude a chemical that attracts the codling moth larva. In some cases kairomones help the underdog. Certain marine mollusks can pick up the scent of their predators, the sea stars, and make their escape.
