“…The idea that stream macroinvertebrate communities are highly resilient to single pulses of insecticides is supported by the findings of Sibley et al [10], who exposed a Canadian headwater stream to a single, 15-min pulse exposure (16 g L Ϫ1 ) of the pyrethroid permethrin. However, several repeated exposures [29] or prolonged exposure [30] might exclude species for as long as 18 months after exposure, as observed by Kreutzweiser and Kingsbury [29].

Pesticides are constantly being applied to agricultural catchments, but little is known about their impact on aquatic biota during natural exposure. In the present study, the impact of the pyrethroid lambda-cyhalothrin was studied in an in-stream mesocosm setup. Twice during the summer of 2002, the natural macroinvertebrate community was exposed in situ to a 30-min pulse of lambda-cyhalothrin. Pyrethroid doses were released through a modified drip set with nominal concentrations of 0.10, 1.00, and 10.0 microg L(-1) during the first exposure and 0.05, 0.50, and 5.00 microg L(-1) in the second exposure. Before, during, and after exposure, drifting macroinvertebrates were caught in nets. Quantitative benthic samples were taken both before and on two occasions after exposure. Macroinvertebrate drift increased immediately after the pulse exposure, with total drift being significantly higher at all concentrations. Gammarus pulex, various Ephemeroptera, Leuctra sp., and Simuliidae were some of the taxa showing the most pronounced drift response. Structural change in the community was found only at 5.00 and 10.0 microg L(-1), and recovery occurred within approximately two weeks. The present study may be valuable in assessing extrapolations based on laboratory results as well as in evaluating pyrethroid impact on natural freshwater environments.

“…Samples fortified at a level of 25 ng L −1 yielded a mean ± standard deviation of 23 ± 2.9 ng L −1 for chlorpyrifos ( N = 218) and 24 ± 1.9 ng L −1 for diazinon ( N = 188). ( 26 ) Compared to the variation in effects data discussed in the following section, analytical variability was negligible in the key threshold concentrations used in the RADAR analysis (22–177 ng L −1 ). Consequently, only the reported point estimates of concentration were utilized in the assessment.…”

An Ecological Risk Assessment for Chlorpyrifos in an Agriculturally Dominated Tributary of the San Joaquin River

Risk Analysis

Single-species toxicity testing of ambient water samples and national-scale probabilistic risk assessment have implicated the organophosphorous (OP) insecticide chlorpyrifos (O, O-diethyl O-(3,5,6-trichloro-2-pyridyl)-phosphorothioate) as a potential chemical stressor of aquatic organisms residing in the lower San Joaquin River basin. This site-specific aquatic ecological risk assessment was conducted to determine the probability of adverse effects occurring from exposure to chlorpyrifos in an agriculturally dominated tributary of the San Joaquin River and to assess the ecological significance of such effects. Assessment endpoints were fish population persistence and invertebrate community productivity. Daily chemical measurements collected over a period of one year were analyzed temporally for frequency, duration, and spacing between events for acute and chronic exposure episodes. Effects thresholds for fish and freshwater lotic invertebrates were determined from single-species laboratory toxicity tests. Potential risk was characterized by the degree of overlap of distributions of exposure events and effects, with consideration given to additive toxicity of other OP insecticides, recovery periods, and duration of chronic exposure (> or = 21 d). Ecological significance was determined by analysis of fish assemblage dietary and reproductive habits in relation to the surrogate invertebrate taxa judged at risk. Results of analysis indicated no direct effects on fish, and indirect effects on fish through elimination of invertebrate food items were considered unlikely. Biological survey information will be necessary to address uncertainty in this risk conclusion, especially as it relates to the benthic invertebrate community. Results of this site-specific risk analysis suggest that fish population persistence and invertebrate community productivity were not adversely affected by measured chlorpyrifos residues during a year-long monitoring period.

“…Although these pyrethroid insecticides are extremely toxic to aquatic invertebrates and vertebrates, their use for aerial application could be limited to sites where no aquatic systems are present or where they could be effectively buffered from the effects of the treatment Kreutzweiser and Kingsbury 1987). A petition to register permethrin as a ground spray against Z. canadensis has been filed in Canada.…”

Status of research on the development of management tactics and strategies for the spruce bud moth in white spruce plantations

The spruce bud moth, Zeiraphera canadensis, represents an economic threat to white spruce, Picea glauca, managed for lumber production in eastern Canada. Larvae feed on developing shoots. Larval feeding on the leader adversely affects tree form and reduces vertical growth. Although the economic impact of this insect has not been critically established, it is feared that this damage could decrease the quality and value of the lumber produced and could delay harvest by several years. This paper reviews the information on the spruce bud moth life cycle, behaviour, impact, sampling and monitoring, and the possible management tactics investigated to date.
