“…Previous work has shown that, at least in its native range, F. auricularia is a potentially important biological control agent of various pests in orchards including leaf‐curling midges and aphids (He, Wang, & Xu, ; Mueller, Blommers, & Mols, ; Nicholas, Spooner‐Hart, & Vickers, ). Various methods to augment the overwintering survival of earwigs in orchards have been described (Carroll & Hoyt, ).…”

Organisms that invade new habitats exploit new resources or niches and influence native species. Here, we examine how an invasive moth, the parsnip webworm (Depressaria radiella, formerly D. pastinacella), facilitates interactions with other arthropods in spatially separated populations of native cow parsnip (Heracleum maximum) in the Rocky Mountains (New Mexico and Colorado). We compare this with results on small hogweed (Heracleum sphondylium) in the Netherlands, where both the plant and herbivore are native. Larvae of D. radiella feed in webs on ripening fruits of their food plants. Mature caterpillars descend the hollow stems into which they chew a hole, enter the stem and pupate. Other arthropods enter the stems through these holes. Plants in all populations of cow parsnip/hogweed contained either moth pupae and/or webworms mummified by their main parasitoid, Copidosoma sosares that also been introduced into parts of the United States. In both countries, earwigs (Forficula auricularia), which are also invasive in the United States, were the dominant arthropod to utilize webworm‐perforated stems, although there was more within‐site variability in abundance of earwigs in the United States than in the Netherlands. The woodlouse, Porcelio scaber, which is native to Eurasia but also established in the United States, was abundant in stems of Dutch hogweeds but absent in stems of American cow parsnips. Other native herbivores (e.g., mirid bugs), were collected in stems at sites in both continents. Moreover, the number of various arthropods found in perforated stems correlate positively with the number of holes found in these stems.

Earwigs are usually considered pest predators in orchards. Because of its worldwide distribution, most research on earwigs focuses on the European earwig Forficula auricularia Linnaeus (Insecta: Dermaptera: Forficulidae). However, very little is known of this species in Mediterranean citrus orchards. Earwigs and aphids were collected monthly during 5 years (2006–2010) from citrus canopies. Two species of earwigs were found: F. auricularia and Forficula pubescens Gené (=Guanchia pubescens), with the latter seldom cited in the literature. The goals of this study were (i) to document the abundance of these two earwig species in Mediterranean citrus canopies; (ii) to determine whether they are positively or negatively associated with each other, or randomly distributed; (iii) to measure the interannual variation of the abundance of both species during a 5‐year period and (iv) to evaluate the potential role of earwigs as pest predators in citrus canopies. As compared to colder regions, F. auricularia active period in citrus canopies in our study site lasted longer. Both species co‐occurred randomly in canopies. In 2006, both species showed approximately the same abundance, but in 2010, F. pubescens abundance in canopies was 28 times greater than that of F. auricularia. The potential role of earwigs as pest predators is higher in the Mediterranean than in other colder regions, because of the longer active period. F. auricularia is a sedentary generalist predator, already present in citrus canopies at the onset of most pest outbreaks, while F. pubescens arrived later to the canopies, but most likely was abundant enough to contribute in the control of citrus pests.

“…According to Lordan et al ( 2014 ), the shelters were prepared by rolling a piece of corrugated cardboard into a cylinder (12 cm height×9 cm diameter), which was protected from rain and adverse conditions by a PVC tube (15 cm height×9.5 cm diameter). Similar shelters have been used in studies of European earwigs elsewhere (Phillips, 1981 ; Helsen et al , 1998 ; Solomon et al , 1999 ; Burnip et al , 2002 ; Gobin et al , 2006 ; Logan et al , 2007 ; He et al , 2008 ; Moerkens et al , 2009 ). Every week throughout the year, we counted the number of earwigs per shelter.…”

Woolly apple aphidEriosoma lanigerumHausmann ecology and its relationship with climatic variables and natural enemies in Mediterranean areas

A multilateral approach that includes both biotic and climatic data was developed to detect the main variables that affect the ecology and population dynamics of woolly apple aphid Eriosoma lanigerum (Hausmann). Crawlers migrated up and down the trunk mainly from spring to autumn and horizontal migration through the canopy was observed from May to August. Winter temperatures did not kill the canopy colonies, and both canopy and root colonies are the source of reinfestations in Mediterranean areas. Thus, control measures should simultaneously address roots and canopy. European earwigs Forficula auricularia (Linnaeus) were found to reduce the survival of overwintering canopy colonies up to June, and this can allow their later control by the parasitoid Aphelinus mali (Haldeman) from summer to fall. Preliminary models to predict canopy infestations were developed.
