A search is being conducted to determine the indigenous parasites and predators of the alfalfa weevil, Hypera postica (Gyll.), in Alberta (Schaber 1981). A clearer understanding of the biology of the predator Odynerus dilectus Saussure will augment control of the alfalfa weevil in an integrated pest management program.Odynerus dilectus has been recorded in the United States (Bohart et al. 1982) and in Alberta, Canada (Strickland 1947). In California, Linsley and Michener (1942) reported that females stocked their nests with small caterpillars, but Bohart et al. (1982) reported that in Utah females of O. dilectus provisioned their nests with larvae of the alfalfa weevil. This paper summarizes data about the nesting and prey-provisioning behavior of O. dilectus in southern Alberta.

A New Species

AbstractMicroctonus stelleri Loan is described as a new species. This euphorine braconid occurs in France, Germany, Sweden, and Russia. It is umvoltine and its only known host is the alfalfa weevil, Hypera postica (Gyllenhal). In the spring the mature parasite larva issues from the overwintered adult host and forms a white cocoon in the ground litter. In about 2 weeks the adult parasite emerges, mates, and oviposits in larva of the alfalfa weevil. The parasite egg hatches and the first-instar larva remains within the host until the following spring. In northern France M. stelleri was the dominant parasite in overwintering adults of H. postica. Parasitism ranged from 0 to 13% though it was usually less than 6%. Laboratory studies showed that M. stelleri females live longer, have a higher rate of oviposition, and parasitize more hosts than females of M. colesi Drea, a parasite of the weevil in the United Slates. A technique is described for the recovery of M. stelleri from adult alfalfa weevils. From 1966 to 1970, 4387 parasites were imported from France and released at 24 localities in the United States.

AbstractThis study examines whether pesticide risk indicators can be used to evaluate the environmental effects of pesticide applications within integrated pest management (IPM) projects. Pesticide risk indicators, commonly used in European countries, are mathematical equations that consider data inputs such as application rates, toxicity levels of a pesticide's active ingredient, meteorological data, the soil characteristics of farm fields, and other information to generate potential risk scores for pesticide applications. These potential risk scores represent the best estimate of a pesticide's impact on the surrounding environment. This project analyzed eight pesticide risk indicators, developed throughout Europe and the United States, with two years of pesticide application data from four farms using IPM. This two-year study allowed for a determination of the validity and reliability of pesticide risk indicators. The findings reveal that only three pesticide risk indicators performed consistently and gave valid results. These indicators are: the synoptic evaluation model for plant protection agents (SYNOPS) indicator from Germany, the multi-attribute toxicity factor from the United States, and the environmental impact quotient from the United States. As a result, the authors recommend these three indicators for future research and for IPM evaluative efforts that emphasize the environmental effects of pesticides.

Recent survey data are examined to improve current understanding of the factors that help to determine the value of information reported on a website that serves as the centerpiece of the USDA's “Soybean Rust Integrated Pest Management—Pest Information Platform for Extension and Education.” Respondents’ initial beliefs about their chances of experiencing a rust outbreak are shown to affect the likelihood that soybean producers will visit the website and change their management of fungicide use as a result.

Supply Information

Integrated pest management (IPM) programs vary from employing field scouts to planting trap crops, as inputs in production, to control crop losses. Scouts provide pest information, helping to determine the need for pesticide applications. This increased information may indicate a reduction of periodic application, which would diminish the negative external effects that such treatments have on environmental quality.Recent research in this area has determined the need for pest information (Regev et al.) and the rationale for established information markets (Feder). Currently, such sources exist throughout the United States, and both public and private consultants supply information to agricultural producers.
