“…Comparing laboratory data. Although the consump tion of seed by different carabid species was studied pre viously by several authors (Goldschmidt & Toft, 1997;Tooley et al, 1999;Lietti et al, 2000) comparison of the consumption rates they recorded is difficult due to differ ences in the species of seed offered, temperature and pre treatment history of the carabids. Goldschmidt & Toft (1997) provide data on the consumption of C. bursapastoris seed by 7 of the carabid species used in our study.…”

“…to those of Umbelliferae. Recent papers reveal they eat the seeds of a number of plant species belonging to many families (Goldschmidt & Toft, 1997;Tooley et al, 1999;Lietti et al, 2000) and that some species can complete their larval development on a diet of seeds (Jorgensen & Toft, 1997b;Hurka, 1998;Saska & Jarosik, 2001). Additionally, many species even cache seeds underground and may live on them for some time (Schremmer, 1960;Manley, 1971).…”

Abstract. The consumption and preferences of polyphagous ground beetles (Coleoptera: Carabidae) for the seeds of herbaceous plants was determined. The seeds were stuck into plasticine in small tin trays and exposed to beetle predation on surface of the ground. In the laboratory the effect of carabid (species, satiation) and seed (species, size) on the intensity of seed predation was investigated. The consumption of the generally preferred Cirsium arvense seed by 23 species of common carabids increased with body size. Seed of Capsella bursa-pastoris was preferred by small carabids and their consumption rates were not related to their size. The average daily consumption of all the carabid species tested (0.33 mg seeds . mg body mass-1 . day-1) was essentially the same for both kinds of seed. Because of satiation the consumption of seed of C. arvense provided ad libitum to Pseudoophonus rufipes decreased over a period of 9 days to 1/3-1/4 of the initial consumption rate. Preferences of P. rufipes (body mass 29.6 mg) and Harpalus afifiinis (13.4 mg) for the seeds of 64 species of herbaceous plants were determined. The small H. afifiinis preferred smaller seed than the large P. rufipes. Predation of seed present on the ground in the field was studied in 1999-2000, at PrahaRuzyne (50°06' N 14°16'E). Seeds were placed in stands of different crops as in the laboratory experiments and vertebrate predation was excluded by wire mesh cages. Pitfall traps placed near the cages revealed that carabids were the only seed predators active in the area. Rates of removal of seed of 6 weed species varied with crop, season, seed and site. Average rate of removal in June-August was 2.5 seeds.day-1.tray-1 and was smaller before and after this period. The rates of removal increased with increasing activity den sity of the carabids and paucity of seed from naturally occurring weeds, which may have satiated the carabids. In stands of winter wheat, millet and soybeans there were significant differences in the rates of removal of the seed of 43 herbaceous species. The field preferences were correlated with those established in the laboratory. Predation of seed on the ground in arable fields can be as high as 1000 seeds.m-2.day-1 and may selectively influence the quantity of seed of particular herb species that enters the soil seed bank. Seed predation thus may be an effective component of weed control on arable land, particularly at low weed densities.

Seed survival and predation of Anoda cristata in soyabean crops

et al. 2005

View full text Add to dashboard Cite

Anoda cristata is a troublesome annual broad-leaved weed in summer crops in the rolling Pampa in Argentina; seeds are the only source of regeneration of this species. Seed persistence or depletion is the result of survival and loss processes, including predation. The objective of this study was to determine survival at two burial depths in undisturbed soil and predation rates of A. cristata seeds in soyabean crops in different rotations and tillage systems. Survival was discontinuous and decreased to 25% after 35 months, after which no further reduction in survival was observed to the end of the experiment at 96 months. No differences in seed survival between seeds placed on the soil surface and buried 5 cm below the soil surface were found at 80 months, but at later times survival was lower for seeds placed on the soil surface. Predation rates ranged between 0.3% day )1 and 6.7% day )1 . Of the models tested, a polynomial regression of the rate of predation with time gave the best representation of seed predation. From January to July, predation was higher in nontillage plots in the wheat/soyabean rotation. There was no significant difference in predation rates between tillage systems in the soyabean monoculture and no difference between planting densities. Higher crop residue levels in non-tillage plots in the wheat/soyabean rotation was the dominant factor influencing seed predation, probably because such habitat favours the presence of seed predators.

“…B. peruvianus has been reported to be one of the most abundant soil predators in the fields of several crops such as sweet potato, asparagus, bean, potato and tomato (Vergara & Amaya de Guerra, 1978;Velapatiño, 1997;Schuller & Sánchez, 2003;Rondón & Vergara, 2004). Among the least abundant species, Notiobia peruviana is considered to be a highly polyphagous species; however, it appears to primarily feed on the seeds of various plants (Nisensohn, Faccini, Montero, & Lietti, 1999;Lietti, et al, 2000;Arndt & Kirmse, 2002, as cited by Yábar, Castro, Melo, & Gianoli, 2006.…”

“…For example, Blennidus peruvianus (Dejean, 1828), which is one of the most abundant soil predators in fields of various crops, including sweet potato, asparagus, beans, corn, potato and tomato (Vergara & Amaya de Guerra, 1978;Velapatiño, 1997;Schuller & Sánchez, 2003;Rondón & Vergara, 2004), along with Tetracha chilensis (Laporte, 1834). However, other species in this family, such as Notiobia peruviana Dejean, are phytophagous and prefer to eat seeds (Lietti, Montero, Faccini, & Nisensohn, 2000, as cited by Castañeda, Sánchez, & Arellano, 2007). Similarly, although most members of the family Staphylinidae are predators of insects and other invertebrates, some species feed on fungi or decomposing organic matter (Arnett & Thomas, 2001).…”
