“…The larvae feed only on the root nodules throughout all 5 larval stages (JOHNSON and O'KEEFFE 1981). Nodules are foodresources of very high quality, but a limited resource (GREENWOOD and BATHURST 1978;HEICHEL and VANCE 1983;SUTTON 1983;QUINN and HOWER 1986).…”

The impact of the pea and bean weevil, S. lineatus, on field beans, V. fuba, was investigated in field cage experiments with controlled attack levels. A decrease in yield up to 28 YO was recorded due to a reduction in the number of pods per plant, whereas the number of seeds per pod and the individual seed weight were unaffected.As the damage was a non-monotonous function of the attack level, the experiment suggests a complex relationshi between attack level and yield loss due to adult weevils feeding on the leaf margins and larvae feeding on the root nodules.The number of larvae shortly before hatching was independent of the adult attack level, as the same numbers of larvae were found in all treatments, thus indicating an increasing mortality at higher population densities. Difficulty of establishment in suitable root nodules and intraspecific competition are considered to be the most important mortality factors.The complex relationship between the attack level and the yield response is discussed in relation to the density dependent mortality of the larvae. A significant correlation between attack level and the number of leaf margin feeding notches following infestation was recorded. This is discussed in relation to monitoring and warning.

“…They very soon commence to lay eggs after their appearance in the crop and egg-laying continues until shortly before the death of the parent weevil (Lerin et al 1993). Larvae burrow into the soil and feed exclusively within Rhizobium nodules associated with pea roots (Johnson & O'Keeffe 1981). This means that infestation damages a pea crop twice a season.…”

(2010): Differences between the effects of insecticidal seed and foliar treatments on pea leaf weevils (Sitona lineatus L.) in the field pea (Pisum sativum L.). Plant Protect. Sci., 46: 19-27.Tested seed treatments (two doses of thiamethoxam, thiamethoxam + fludioxonil + metalaxyl-M; two doses of clothianidin + beta-cyfluthrin) showed high effects on pea leaf weevils (Sitona lineatus L.) which approved relatively long-lasting and sufficient protection of several bottom nodes of stipules simultaneously. The effects of foliar treatments (chlorpyrifos + cypermethrin; acetamiprid, lambda-cyhalothrin) sometimes were evident only on the node which was determined as the youngest node at the time of spraying. The effects of the compared seed and foliar treatments on the reduction of S. lineauts larvae numbers on roots were not proven as positive. It is possible to conclude that the foliar application had no real effect in this sense at all. However, positive significant effects of thiamethoxam and clothianidin + beta-cyfluthrin on root nodulation in general were recorded. Especially higher doses of the seed treatments increased overall nodulation from 43% till 363%.

“…Adults feed on newly emerging pea plants and females oviposit on the soil near the root collar. Newly emerged larvae move into the soil and feed on the root nodules formed by the symbiotic bacterium Rhizobium leguminosarum (Johnson & O'Keeffe, 1981). Both immature and adult stages can cause significant damage to pea plants resulting in yield losses (Williams et al, 1995;Lohaus & Vidal, 2010).…”

The pea leaf weevil, Sitona lineatus L., is periodically a significant pest of pea, Pisum sativum L., in the Palouse region of northern Idaho and eastern Washington, USA. Previous on-station research demonstrated significantly greater adult pea leaf weevil colonization, immature survival, adult emergence and plant damage in conventional-tillage compared to no-tillage plots of pea. In experiments conducted during the 2006 and 2007 growing seasons, aerial and ground adult pea leaf weevil colonization of large-scale commercial pea fields under different tillage regimes in northern Idaho and eastern Washington was examined for the first time. Initial pea leaf weevil feeding damage, immature weevil densities and subsequent adult emergence from the fields were also assessed. During both years, significantly more adult pea leaf weevils were captured in conventional-tillage than in no-tillage fields during the crop establishment period in May. No-tillage soils remained wet longer in the spring and could not be planted by growers until later than conventional-tillage fields. Pea planted under conventional-tillage emerged earlier and had significantly greater feeding damage by the pea leaf weevil than no-tillage pea. Significantly, greater immature pea leaf weevil densities and subsequent adult emergence were observed in conventional-tillage than in no-tillage pea fields. Delayed development of root nodules in the cooler, moister conditions of no-tillage pea fields likely resulted in escape from attack and injury during the critical growth stages that ultimately influence yield. Results indicate that large-scale commercial no-tillage pea fields are less suitable for colonization and survival of the pea leaf weevil and suffer less weevil damage than fields under conventional tillage.
