For example, Fairfax Biologicals markets its product under the trade name ” Doom “. Trehalose, the sugar found in insect haemolymph, is a favoured carbon source though glucose also baxillus be used. Back to Pathogens Table of Contents.

Management and manipulation of the environment to favour the activities of naturally occurring control agents. Type B disease differed in that the grubs showed a transition from white to brown over winter and the bacterium causing this disease was named B.

Views Read Edit View history. It is also a problem in the larval stage because the adult beetles lay their eggs in grass turf and the grubs destroy the grass roots, especially on new housing estates where natural enemies are absent.

Although it is not a problem in its area of origin, the beetle causes serious damage in the USA. Pages People more options. The cause of insect death is not fully known. Poplliae the s, the infestation had become so extensive that a search for a control measure was undertaken which led to the discovery in nature of some diseased larvae.


Biological Control

The spores so engendered have survived ;opilliae in air and subsequent storage for several months as dry films and also in dry soil, sand, and a mixture of powdered calcium carbonate and talc. In field conditions, however, there are reports that larvae sometimes die earlier, before the main phase of sporulation is completed. Much of the text below has been copied and updated from a book now out of print [JW Deacon, It spread rapidly from the popilliqe sightings in New Jersey and today it is found over roughly half of the country, in almost every state east of the Mississippi.

Milky spore

In this section we discuss the use of a bacterium, Bacillus popilliaeto control a major introduced pest in the USA. Also, a recent field study in Kentucky showed that commercial formulations of P.

A bafillus of other milky disease bacteria were poopilliae from beetle hosts throughout the world, but the trend now is to regard all of these as varieties of B.

The adult Japanese beetles pupate in July in the Northeast United States and feed on flowers and leaves of shrubs and garden plants. Physiological starvation caused by the growth of bacterial cells in the haemolymph seems the most likely explanation, and fat reserves of diseased larvae have been shown to be much reduced compared with those of healthy larvae. An example of this is the use of Bacillus popilliae to control the Japanese beetle in the USA, discussed below. Actually there are a number of oligosporogenic mutants – ones that produce a few spores – but spores for microbial control programmes are usually produced in living insect larvae – an expensive and time-consuming process.


The advantages of using commercial preparations of P. The host-parasite interaction B. It is responsible for a disease commonly called milky spore of the white grubs of Japanese beetles. Van Nostrand Reinhold, Wokingham]. Injection of healthy larvae of the Japanese beetle, as the first stage in production of commercial spore powders. Examples of this include the use of Bacillus thuringiensisPhlebiopsis gigantea bxcillus Agrobacterium radiobacter.
