“…As a result, females become sexually active when they have access to the bean pods, which are the main egg-laying substrate (Tran and Huignard 1992), but the pods of the lower third of the stem develop first. In males, sexual activity is stimulated by an extension of the photoperiod to 16 light hours (Segers et al 2021). These factors promote that, depending on environmental circumstances, such as the timing of the bean sowing and pace of development of the plants, which depends significantly on meteorological conditions, egg-laying may take place significantly earlier or later in various fields in various years.…”

“…Individuals using this strategy hibernate somewhere in shelters found in the environment. The second strategy is a slowed-down or decelerated development, because of which the imagines develop completely in the harvested seeds, where they also overwinter (Medjdoub-Bensaad et al 2015;Segers et al 2021). The reasons for choosing a specific development strategy are not yet known.…”

The broadbean seed beetle (Bruchus rufimanus Boheman, 1833) is a major pest of faba bean (Vicia faba L.) almost everywhere this crop is grown. The main tasks of this research were to study the seed beetle's phenology, and rates of egg laying, larval survival and the emergence of young adults before the harvest. Studies were done in field conditions in farms located in various places in Latvia. The highest density of imagines was observed at a time when the plants were flowering intensively. Egg laying began as soon as the pods had formed in the lower third of the stem and lasted 4-5 weeks. In severe infestation happened, more than 34 eggs were laid per pod. The percentage of damaged yield increased in proportion to the average number of eggs laid on pods until this number reached 11-12 eggs per pod and remained at approximately the same level also when egg-laying rate was higher. In several fields, no seeds with imago exit holes were found in the samples few days before harvest, while in other sowings, the proportion of such seeds exceeded 90% of the total amount of damaged yield.

“…A key pest in faba bean is Bruchus rufimanus (Boh.) (Segers et al, 2021). Adult beetles colonise the crop in spring to feed on pollen and nectar, and start laying eggs on developing pods (Segers et al, 2021).…”

“…(Segers et al, 2021). Adult beetles colonise the crop in spring to feed on pollen and nectar, and start laying eggs on developing pods (Segers et al, 2021). When the larvae hatch, they bore through the pods and develop and feed inside the beans.…”

“…We use the term 'herbivory' to include both florivory by the B. rufimanus adults and seed predation by the larvae. Larval feeding reduces seed weight and quality (Epperlein, 1992;Roubinet, 2016;Segers et al, 2021). Adult beetles might have additional negative effects on yield if their feeding on pollen disrupts pollinator visitation (Ye et al, 2017), or, alternatively, positive effects if they pollinate (Krupnick & Weis, 1999;McCall & Irwin, 2006).…”

Identifying and quantifying crop stressors interactions in agroecosystems is necessary to guide sustainable crop management strategies. Over the last 50 years, faba bean cropping area has been declining, partly due to yield instabilities associated to uneven insect pollination and herbivory. Yet, interactions between pollinators and a key pest, Bruchus rufimanus (florivorous and seed predating herbivore), on faba bean yield have not been investigated. Using a factorial cage experiment in the field we investigated how interactions between two potential stressors, lack of pollination from Bombus terrestris and herbivory by B. rufimanus, affect faba bean yield. Lack of insect pollination reduced bean weight per plant by 15%. Effects of B. rufimanus herbivory differed between the individual plant and the plant-stand scale (i.e. when averaging individual plant scale responses), likely due to high variation in the level of herbivory among individual plants. At the individual plant scale, B. rufimanus herbivory increased yield but only in the absence of pollinators, possibly due to plant over-compensation and/or pollination by B. rufimanus. At the plant-stand scale, we found no effect of B. rufimanus on yield. However, there was a tendency for heavier individual bean weight with insect pollination, but only when B. rufimanus herbivory was absent, possibly due to a negative effect of B. rufimanus on the proportion of legitimate flower visits by B. terrestris. This is the first experimental evidence of interactive effects of B. terrestris and B. rufimanus on faba bean yield. Our preliminary findings of negative and indirect associations between B. rufimanus and individual bean weight call for a better acknowledgment of these interactions in the field in order to understand drivers of crop yield variability in faba bean. This study showed that herbivory can increase yield, but this effect is only detectable when investigated in combination with lack of pollination.

Identifying and quantifying crop stressors interactions in agroecosystems is necessary to guide sustainable crop management strategies. Over the last 50 years, faba bean cropping area has been declining, partly due to yield instabilities associated with uneven insect pollination and herbivory. Yet, the effect of interactions between pollinators and a key pest, the broad bean beetle Bruchus rufimanus (florivorous and seed predating herbivore) on faba bean yield has not been investigated. Using a factorial cage experiment in the field, we investigated how interactions between two hypothesized stressors, lack of insect pollination by bumblebees and herbivory by the broad bean beetle, affect faba bean yield. Lack of bumblebee pollination reduced bean weight per plant by 15%. Effects of the broad bean beetle differed between the individual plant and the plant‐stand level (i.e., when averaging individual plant level responses at the cage level), likely due to high variation in the level of herbivory among individual plants. At the individual plant level, herbivory increased several yield components but only in the absence of pollinators, possibly due to plant overcompensation and/or pollination by the broad bean beetle. At the plant‐stand level, we found no effect of the broad bean beetle on yield. However, there was a tendency for heavier individual bean weight with bumblebee pollination, but only in the absence of broad bean beetle herbivory, possibly due to a negative effect of the broad bean beetle on the proportion of legitimate flower visits by bumblebees. This is the first experimental evidence of interactive effects between bumblebees and the broad bean beetle on faba bean yield. Our preliminary findings of negative and indirect associations between the broad bean beetle and individual bean weight call for a better acknowledgment of these interactions in the field in order to understand drivers of crop yield variability in faba bean.
