“…The percentage of seed infestation is directly related to the size of the population of adult weevils in the pea crop in the spring. Pea cultivars with a lower protein and phosphorus content had a lower level of damage (Nikolova, 2016a). Therefore, it can be assumed that pea from Hissar had a higher protein and phosphorus content.…”

“…Bruchid infestation levels can be also restricted by the braconid wasp Triaspis thoracicus Curtis, an endoparasitoid (Hymenoptera: Braconidae) that feeds on developing bruchid larvae and increase their mortality (Tsialtas et al, 2020). With few exceptions, T. thoracicus is a specialized parasitoid of the genus Bruchus, which includes various species of economic importance for stored legumes (Nikolova, 2016a;Reddy et al, 2018). Triaspis thoracicus attacks the early-stage larvae of the pest within the seed.…”

“…It turned out that every reexamination of the same plant material was combined with mechanical damage on seeds affected by the activity of a phytophagous insect pest. The Harmfulness coefficient (q, %) was calculated by the formula used by Nikolova (2016a): q = (a -b)/a × 100 (a-weight of 1000 apparently healthy seeds; b-the weight of 1000 damaged seeds).…”

“…This still corresponds with the fact that as much as 30% of individual seed weight is lost from larval feeding (Hardie and Micic, 2020). The losses in seed weight vary depending on the cultivars from 14.6 to 35.0% because of harmful effects to pea weevil (Nikolova, 2016a). The loss in the weight of the cultivars with a higher TGW has lower rates of damage and lower values of a harmfulness coefficient (Nikolova, 2016a).…”

A find of 2572 charred seeds of pea (Pisum sativum L.) was detected at the Late Bronze Age tell settlement Hissar near Leskovac, in Serbia, belonging to the Brnjica cultural group, 14-10 cent. BC. Two types of pea seeds were observed: apparently healthy seeds and seeds damaged by the activity of a weevil (Coleoptera, Bruchidae). At least two-fifths of all finds have apparently been infested most probably by pea weevil (Bruchus pisorum L.), one of the most important pea pests worldwide, especially in medium-moist and dry climates, such as Southern Europe and Australia. A large amount of infested pea seeds indicates a developed pea production on small plots, strongly indicating that cultivating this ancient pulse crop must have been well-rooted in field conditions. Previous DNA analyses of charred pea placed the ancient Hissar pea at an intermediate position between extantly cultivated pea (P. sativum L. subsp. sativum var. sativum) and a wild, winter hardy, 'tall' pea (P. sativum subsp. elatius (Steven ex M. Bieb.) Asch. et Graebn.). Based on an assumption of its late harvest time and combined with pea weevil life cycle stage in charred seeds, it was possible to estimate the season during which the seeds were carbonized, namely, the second half of July or the first days of August at the latest. Older, final weevil instars were predominant before seed carbonization. The pea infestation rate at Hissar is one of the highest noted among pulses in the Old World and the highest among peas, so far.

A major constraint of lentil (Lens culinaris Medik.) cultivation is yield reduction due to field infestation by the seed beetles Bruchus spp. (bruchids). The aim of the study was to assess seed loss (SL) and yield loss (YL) due to bruchid infestation under organic and conventional farming, and to investigate genotypic variability for seed yield of 20 lentil varieties in response to bruchid damage. Field experiments were established over three consecutive years in two areas of central and northern Greece. SL was determined as the percentage of damaged seeds, whereas the weight of the damaged seeds was estimated as YL. Farming system was the main source of variation for both SL and YL. Mean SL under organic farming was 15% and mean YL was 0.13 t ha–1. SL and YL were 2.6- and 8.4-fold higher, respectively, under organic than conventional farming. Valuable genotypic variability was observed with respect to both SL and YL. Early flowering and small seed size were traits associated with low SL and YL. Among varieties, mean SL ranged from 8.5% to 29.2% and YL from 0.06 to 0.31 t ha–1. Evaluation for high yield potential, indicating bruchid tolerance, revealed two types of promising varieties: varieties with high yield and low seed bruchid damage due to phenological escape, and varieties with high yielding potential despite the high SL and YL.
