Low Rate

Since 1986 several isolated stands of chestnut (Castanea sativa) located north of the Swiss Alps have been infected with the chestnut blight fungus (Cryphonectria parasitica). At all sites (1–3), the diversity of the vegetative compatibility types was low. To control the disease, the hypovirus CHV1 was introduced at seventeen sites in five cantons. In total, 571 cankers were treated with local C. parasitica isolates containing CHV1. Re-inspection of the cankers one to two years after treatment demonstrated that the percentage of active cankers was significantly reduced in three cantons. Re-isolations of C. parasitica showed that the hypovirus persisted in 33% to 75% of the treated cankers and was disseminated to new cankers at a low rate. The difficulties and the potential of hypovirus treatment of small chestnut stands are discussed.

A proposal for the development of a world-wide biological control organisation

It has been proposed that the existing Organisation Internationale de Lutte Biologique (a mainly western European and Mediterranean body) should be enlarged and restructured to form a world-wide International Organisation for Biological Control. IOBC would be open to individual as well as institutional members, and would have largely autonomous regional sections in different parts of the world. IOBC is expected to come into being early in 1971.

RésuméLe charançon perceur de tiges, Mecinus janthinus (Germar), est un agent de lutte biologique classique bien établi et prometteur pour le contrôle d'une mauvaise herbe exotique invasive, la linaire à feuilles larges (Linaria dalmatica (L.) Mill.) (Scrophulariaceae). Dans cet article, nous présentons des caractéristiques du rostre faciles à identifier, permettant la différenciation, à faible grossissement, des sexes de charançons perceurs de tiges vivants. Ces caractéristiques peuvent être utilisées par des travailleurs possédant une formation minimale afin d'identifier correctement le sexe des charançons. Ceci permettra donc une détermination rapide de la proportion des sexes des populations sur le terrain, améliorant ainsi les délais de capture, puis de lâchers.

Bean Beetle

As part of a continual search for potential pathogens of insects for use in biological control or on an integrated pest management program, two bacilliform virus-like particles (VLP) of similar morphology have been found in the Mexican bean beetle Epilachna varivestis Mulsant and the house cricket, Acheta domesticus (L. ).Tissues of diseased larvae and adults of E. varivestis and all developmental stages of A. domesticus were fixed according to procedures previously described. While the bean beetles displayed no external symptoms, the diseased crickets displayed a twitching and shaking of the metathoracic legs and a lowered rate of activity.Examinations of larvae and adult Mexican bean beetles collected in the field in 1976 and 1977 in Maryland and field collected specimens brought into the lab in the fall and reared through several generations revealed that specimens from each collection contained vesicles in the cytoplasm of the midgut filled with hundreds of these VLP's which were enveloped and measured approximately 16-25 nm x 55-110 nm, the shorter VLP's generally having the greater width (Fig. 1).

In the late 1970s, Brazilian peppertree, Schinus terebinthifolia Raddi (Sapindales: Anacardiaceae), was targeted for classical biological control in Florida because its invasive properties (see Host Plants) are consistent with escape from natural enemies (Williams 1954), and there are no native Schinus spp. in North America. The lack of native close relatives should minimize the risk of damage to non-target plants from introduced biological control agents (Pemberton 2000). [...]
