“…Two types of traps were used to monitor the dispersal of S. lineatus from the perennial legu- minous overwintering crops to the field bean summer crop: yellow sticky traps and yellow cone traps. The sticky traps were made up of two yellow PVC-sheets (15x21cm) (Rebell| Amarillo: Fruchtfliegenfallen) put together at a right angle, and placed on a pole 1.5 m above the ground, where S. lineatus has its highest flight density according to Fisher & O'Keeffe (1979).…”

“…S. lineatus colonises annual leguminous crops in the spring, either by flight or in the case of low temperatures by walking (Hans, 1959;Fisher & O'Keeffe, 1979;Hamon et al, 1987). Egg-laying starts immediately if the weevils have previously foraged on perennial legumes.…”

The spring dispersal of Sitona lineatus L. (Coleoptera; Curculionidae) was investigated on a Danish farm. S. lineatus dispersed by flight in the early spring on sunny, calm days with temperatures above ca. 15 °C. Two thirds of the population of S. lineatus dispersed from perennial leguminous crops (clover and lucerne) in the first period of flight activity. The next dispersal did not occur until one month later despite several intermediate flight activity periods. The first period of dispersal occurred before the germination of the spring sown summer host crop, Vicia faba L. The field bean crop was infested in three later invasions during a period of more than three weeks. The aggregation pheromone, 4‐methyl‐3,5‐heptanedione, had a significant effect on captures of both males and females in cone traps placed on the ground. There was no effect of the pheromone on captures in yellow sticky traps placed 1.5 m above ground. The pheromone effect is discussed in relation to behavioural observations. Both types of traps may be used in a survey system for monitoring spring dispersal of S. lineatus and optimal timing of insecticide spraying. However, the pheromone cone traps were highly specific whereas all kinds of flying insects were caught in the yellow sticky traps, thus making the latter traps less suitable for monitoring.

“…Larval feeding reduces seed protein content, especially in nutrient‐poor soils, and the amount of nitrogen returned to the soil (Doré and Meynard 1995; Corre‐Hellou and Crozat 2005). Control of S. lineatus using insecticides is difficult as a result of its high fecundity (Jackson 1920), migratory behaviour (Fisher and O’Keeffe 1979; Hamon et al. 1987), and concealed larval habitat (Jackson 1920); however, the egg stage of S. lineatus is prone to mortality.…”

Sitona lineatus L., the pea leaf weevil, is an invasive pest of Pisum sativum L. (field pea) that has recently become established in Alberta, Canada. Adults consume seedling foliage and larvae feed on Rhizobium root nodules thereby reducing nitrogen fixation; both life stages can reduce yield. Eggs and adults are vulnerable to predators and parasitoids. In 2009, a series of experiments was undertaken to identify potential indigenous natural enemies of S. lineatus in southern Alberta. In three test arenas, eggs were exposed to starved ground beetles in no‐choice tests for 48 h. Egg debris was observed when eggs were exposed to Bembidion quadrimaculatum L., Microlestes linearis (LeConte), Bembidion rupicola (Kirby), Bembidion timidum (LeConte), Poecilus scitulus LeConte, and staphylinid beetles. Of the two most abundant carabid species, the smaller B. quadrimaculatum consistently removed significantly more eggs (94.6%) than the larger Pterostichus melanarius (17.4%). Similar results were observed in Petri dish and egg card tests. No egg debris was observed in tests with Pt. melanarius. Presence of the larger beetle, Pt. melanarius, resulted in a lower rate of egg removal by the smaller B. quadrimaculatum relative to the rates observed for B. quadrimaculatum alone. Intraguild predation of B. quadrimaculatum by Pt. melanarius was observed in 47% of tests. These results suggest that B. quadrimaculatum is a potential predator of S. lineatus eggs in field pea agroecosystems and should be considered for use in conservation biological control and integrated pest management programs.

“…Spring pea is an important pulse crop in the cereal‐legume rotation on the Palouse, with approximately 20% of the acreage planted at any given time to pea or lentil [ Lens culinaris Medikus (Fabaceae)] (Papendick, 1996). Adult PLW aggregate and overwinter on perennial legumes such as alfalfa [ Medicago sativa L. (Fabaceae)], and subsequently migrate to pea fields during the early spring in response to air temperatures and photoperiod (Fisher & O’Keeffe, 1979). The larvae subsequently burrow into the soil and feed within Rhizobium nodules associated with pea plant roots (Johnson & O’Keeffe, 1981).…”

Conversion from conventional‐tillage (CT) to no‐tillage (NT) agriculture can affect pests and beneficial organisms in various ways. NT has been shown to reduce the relative abundance and feeding damage of pea leaf weevil (PLW), Sitona lineatus L. (Coleoptera: Curculionidae) in spring pea, especially during the early‐season colonization period in the Palouse region of northwest Idaho. Pitfall traps were used to quantify tillage effects on activity‐density of PLW in field experiments conducted during 2001 and 2002. As capture rate of pitfall traps for PLW might be influenced by effects of tillage treatment, two mark‐recapture studies were employed to compare trapping rates in NT and CT spring pea during 2003. Also in 2003, direct sampling was used to estimate PLW densities during the colonization period, and to assess PLW feeding damage on pea. PLW activity‐density was significantly lower in NT relative to CT during the early colonization period (May) of 2001 and 2002, and during the late colonization period (June) of 2002. Activity‐density was not different between treatments during the early emergence (July) or late emergence (August) periods in either year of the study. Trap capture rates did not differ between tillage systems in the mark‐recapture studies, suggesting that pitfall trapping provided unbiased estimates of PLW relative abundances. PLW absolute densities and feeding damage were significantly lower in NT than in CT. These results indicate that NT provides a pest suppression benefit in spring pea.
