Abstract

of course, precludes its use for biocontro1. Such records are obtained from field and literature surveys. Ideally, field surveys include plant species and genera related to the. target weed: a survey for thistle and knapweed insects in Europe covered all available members of the tribe Cynareae (77); f or insects of Rhamnus cathartica, additional species and genera of Rhamna­ ceae were searched (51) ; for insects of Cytisus scoparius, a broad range of Leguminosae were included (56); and to obtain information on insects of CuscutaJ 10 species of the genus w ere surveyed (5). Broad surveys such as and the probable host range in the country of introduction. The absence of these reveal the preferences and host range of the ins ects in the study area the insect from plants related to the weed after a thorough field survey is the best single index of host spec ificity. A literature search for host records is always made before a weed insect is used for, biocontrol. If the insect is an important pest, this soon becomes apparent although individual literature records are not necessarily reliable. Incorrect records result from transient insects and from misidentification of either insect or host.
