“…Wei et al (1995) found that asilid larvae (Diptera: Asilidae) can reduce white grub populations and damage to wheat seedlings by 21-99% and 68-96%, respectively. Ants and predatory Coleoptera were identified as important egg predators of the Japanese beetle Popillia japonica Newman (Scarabaeidae) (Terry et al 1993;Lopez and Potter 2000;Zenger and Gibb 2001). To date, however, no quantitative data are available on the invertebrate key predators of M. melolontha, P. horticola and A. solstitiale.…”

Detecting predation and scavenging by DNA gut-content analysis: a case study using a soil insect predator-prey system

White grubs (larvae of Coleoptera: Scarabaeidae) are abundant in below-ground systems and can cause considerable damage to a wide variety of crops by feeding on roots. White grub populations may be controlled by natural enemies, but the predator guild of the European species is barely known. Trophic interactions within soil food webs are difficult to study with conventional methods. Therefore, a polymerase chain reaction (PCR)-based approach was developed to investigate, for the first time, a soil insect predator-prey system. Can, however, highly sensitive detection methods identify carrion prey in predators, as has been shown for fresh prey? Fresh Melolontha melolontha (L.) larvae and 1- to 9-day-old carcasses were presented to Poecilus versicolor Sturm larvae. Mitochondrial cytochrome oxidase subunit I fragments of the prey, 175, 327 and 387 bp long, were detectable in 50% of the predators 32 h after feeding. Detectability decreased to 18% when a 585 bp sequence was amplified. Meal size and digestion capacity of individual predators had no influence on prey detection. Although prey consumption was negatively correlated with cadaver age, carrion prey could be detected by PCR as efficiently as fresh prey irrespective of carrion age. This is the first proof that PCR-based techniques are highly efficient and sensitive, both in fresh and carrion prey detection. Thus, if active predation has to be distinguished from scavenging, then additional approaches are needed to interpret the picture of prey choice derived by highly sensitive detection methods.

“…This is indicated by the higher preference of S. frugiperda and Agrotis ipsilon (Lepidoptera: Noctuidae) for young plants with lower amounts of these compounds (Potter et al, 2008), and the lower survival and development rates of ants among plants rich in the same, thus confirming the fact that basic substances such as alkaloids may affect the digestive tract of insects (López & Potter, 2000).

Phytochemistry and quantification of polyphenols in extracts of the Asteraceae weeds from Diamantina, Minas Gerais state, Brazil

et al. 2012

Asteraceae weeds are rich in chemicals that have biological and pharmaceutical activities. The aims of this work were to describe the phytochemistry and quantify the polyphenols in ethanol extracts from leaves of 12 species of Asteraceae weeds collected in Diamantina, Minas Gerais State, Brazil. The screening of Asteraceae extracts revealed the presence of tannins, steroids, triterpenes, anthocyanins, and flavonoids. The total phenolic content was high in extracts of Lychnophora ericoides (147.97 ± 2.66), Lepidaploa lilacina (141.11 ± 1.99), and Eremanthus elaeagnus (134.61 ± 7.81) and low in extracts of Lychnophora ramosissima (32.65 ± 0.70), and Lychnophora sp. (54.03 ± 0.73). Extracts of Asteraceae weeds from Diamantina could have potential for biological studies that are searching for new pesticides and drugs.

“…Ant baits Ants typically are the dominant predators in turf systems (Cockfield and Potter 1984;Lόpez and Potter 2000;Zenger and Gibb 2001; Potter 2014) so we further assessed their populations using two types of baits (Gotelli et al 2011). Protein baits consisted of 7 g of canned tuna in oil.…”

“…Eggs and larvae of the black cutworm, Agrotis ipsilon, a foliage-feeding turfgrass pest that is attacked by generalist predators (e.g., ants, Carabidae, Staphylinidae, spiders) and parasitoids in turf settings (Lόpez and Potter 2000;Frank and Shrewsbury 2004;Bixby-Brosi and Potter 2012a, b), were used as sentinel prey. The assays were performed on four dates coinciding with the previously described arthropod sampling periods in June and September 2011 and May and July 2012.…”

Naturalized habitat on golf courses: source or sink for natural enemies and conservation biological control?

Many golf courses are converting out-of-play areas to meadow-like habitat to reduce mowing, irrigation, and chemical inputs. Such naturalized roughs, which often constitute 50 % or more of a course's total acreage, support biodiversity by providing habitat for pollinators and other wildlife. This study explored the hypothesis that they also serve as reservoirs of invertebrate natural enemies whose services extend to suppress pests in adjacent mowed turf. We used vacuum sampling, pitfall traps, and ant baits to compare arthropod populations in grassland or meadow-type naturalized roughs and traditional mowed roughs at two courses, and tested for spillover of biological control using sentinel eggs or larvae of a grass-feeding caterpillar exposed near or farther from naturalized areas into mowed turf. Although some natural enemies (e.g., spiders) were more abundant in naturalized roughs, we saw no direct spillover of predation which was quite high regardless of habitat type. Most likely that is because ground-nesting ants (Lasius, Solenopsis, and Pheidole spp.), which are dominant predators in this system, were equally or more abundant in the mowed turfgrass. Herbivorous insects, too, were more abundant in naturalized roughs, so prey availability may discourage solitary ground-dwelling predators from leaving those refuges to forage in mowed areas. There was no parasitism of sentinel eggs or larvae in our trials. Despite absence of direct spillover of predation, we argue that naturalized roughs might be more purposely designed and managed to promote parasitoids, insectivorous birds, and other enemies that provide diffuse biological control services elsewhere on the course.Land-use planners and landscape managers are being challenged to design relatively more sustainable landscapes that provide for the aesthetic, restorative, and recreational needs of Urban Ecosyst
