“…Predator species from different insect families have been observed in the study area, including Coccinelidae (Coleoptera), Syrphidae (Diptera), Chrysopidae (Neuroptera) and small spiders, which is consistent with data for aphid predators in other habitats [32,33]. However, most of these individuals were observed only occasionally, except larvae and adults from the tribe Coccinellini (Coccinelidae), which were often observed on thistles with aphids.…”

Bottom-up effects may not reach the top: the influence of ant–aphid interactions on the spread of soil disturbances through trophic chains

et al. 2012

Soil disturbances that increase nutrient availability may trigger bottom-up cascading effects along trophic chains. However, the strength and sign of these effects may depend on attributes of the interacting species. Here, we studied the effects of nutrient-rich refuse dumps of the leaf-cutting ant, Acromyrmex lobicornis, on the food chain composed of thistles, aphids, tending ants and aphid natural enemies. Using stable isotopes tracers, we show that the nitrogen accumulated in refuse dumps propagates upward through the studied food chain. Thistles growing on refuse dumps had greater biomass and higher aphid density than those growing in adjacent soil. These modifications did not affect the structure of the tending ant assemblage, but were associated with increased ant activity. In contrast to the expectations under the typical bottom-up cascade effect, the increase in aphid abundance did not positively impact on aphid natural enemies. This pattern may be explained by both an increased activity of tending ants, which defend aphids against their natural enemies, and the low capacity of aphid natural enemies to show numerical or functional responses to increased aphid density. Our results illustrate how biotic interactions and the response capacity of top predators could disrupt bottom-up cascades triggered by disturbances that increase resource availability.

PREDATORY CAPACITY OF Adalia angulifera (COLEOPTERA: COCCINELLIDAE) LARVAE ON Myzocallis coryli (HEMIPTERA: APHIDIDAE) IN CHILE

A. Aguilera, R. Neculmán, and R. Rebolledo. 2014 Predatory capacity of Adalia angulifera (Coleoptera: Coccinellidae) larvae on Myzocallis coryli (Hemiptera: Aphididae) in Chile. Cien. Inv Agr. 41(1): 81-88. In La Araucanía, the filbert aphid Myzocallis coryli (Goeze) is a pest that can cause various types of damage to hazelnut (Corylus avellana L.) including reduction in nut size and nut emptiness. M. coryli can also leave hazel leaves susceptible to the fungus known as fumagina (Capnodium sp.), which causes decreased photosynthesis, particularly during the period when the tree is storing reserves for the following season. Knowledge about the natural enemies of M. coryli in Chile is in its early stages compared with other countries where the hazelnut crop is more extensive. Indeed, only 13 entomophagous predators have been recorded in La Araucanía thus far, including one Hemerobiidae, one Syrphidae, one Cecidomyiidae and ten Coccinellidae. Of this last family, Adalia is the best represented genus, with three species. In this study, the life cycle of the Adalia angulifera Mulsant (Coleoptera: Coccinellidae) has been ascertained. M. coryli as its food, and the ability of the larvae to prey on the same aphid is presented here. This study took place under semicontrolled laboratory and greenhouse conditions in the Region of the Araucanía, Chile. This study showed that the average predatory capacity of the A. angulifera larvae was 127.60± 33.21 specimens of M. coryli. For each larval instar (L), it was determined that the daily average prey was 6.8 ± 2.45 aphids for L I; 14.64 ± 5.77 aphids for L II; 42.72 ± 17.12 aphids for L III and 63.44 ± 26.21 aphids for L IV.

“…The ontogeny and ethology of this family has been studied in Chile by Rivera (1904), Montes (1970), Etchegaray (1982), Aguilera, (1995) and Aguilera et al (2006a), who describe the Coccinellidae biology, postural habits, description and duration of larval stage, environmental conditions influencing de development and hibernation cycle of the species in adult state. There are also outstanding works by Zúñiga (1967Zúñiga ( , 1985, González (1969), Carrillo et al, (1974), Lamborot and Guerrero (1979), Zúñiga et al (1986), Prado (1991), Aguilera and Pacheco (1995), Grez and Prado (2000), Grez and Villagrán (2000), Aguilera et al (2006aAguilera et al ( , 2006b who research aspects on the predatory activity of this family.

Comparison of relative abundance and diversity of coccinellids (Coleoptera: Coccinellidae) in blueberries (Vaccinium corymbosum L.), under two production systems in the La Araucanía Region, Chile

2010

In Chile, this family was composed in 1989 by 33 genus and 76 species (Elgueta and Arriagada, 1989). González (2006) mentions that there are represented five Coccinellidae subfamilies in the country: Coccidulinae, Coccinellinae, Exoplectrinae, Scymninae and Sticholotidinae. There is currently a record of 93 coccinellid species in Chile (González, 2008). The species of the Coccinellinae and Scymninae subfamilies feed mainly from Aphididae, while Sticholotidinae and Exoplectrinae feed more frequently from coccids. There is not sufficient information on Chilean Coccidulinae, although there are aphidophagus and coccidophagus species (González, 2006).
