“…It is a polyphagous species reported to feed on Cacopsylla pyri (L.) (Hemiptera: Psyllidae) and Brevicoryne brassicae (L.) (Hemiptera: Aphididae) [ 56 , 85 , 86 ]. This is the first report showing that it predates upon M. hellenica .…”

Predators of the giant pine scale, Marchalina hellenica (Gennadius 1883; Hemiptera: Marchalinidae), out of its natural range in Turkey

Marchalina hellenica is a sap sucking scale insect endemic to the Aegean basin and it has been introduced to several regions in Greece and Turkey to increase pine honey production. It is also considered as a pest since heavy infestation may leave the host trees vulnerable to secondary pests. An understanding of its natural predators would facilitate planning biocontrol programs. Although there are several studies reporting the predators of M. hellenica in its native range, there is no study identifying those in its introduced range. We aimed to determine predators of M. hellenica in Burdur, one of its introduced sites in Turkey. We carried out sampling through regular visits in an M. hellenica-infested locality nearby Burdur Lake. Through field and laboratory observations, we identified 19 species predating upon M. hellenica. Comparing predators reported in previous studies in its native range and those we found in the present study showed that 12 of the species that we found are new reports for the species predating upon M. hellenica. The highest number of predator individuals belonged to the monophagous Neoleucopis kartliana. Myrrha octodecimguttata, Chilocorus bipustulatus and Harmonia quadripunctata were also the most frequently observed predators.

“…Others, however, found decreased or unchanged density (Roy et al 2004, Adler et al 2007, reduced adult survival (Ma et al 2004), or increased time and resources dedicated to avoiding heat stress (Ma and Ma 2012). Some studies found that predation rates increase with temperature (Jalali et al 2009, Simonsen et al 2009), whereas others have found that attack rates for some predators peak near ambient temperatures (Khan and Khan 2010) or only increase with temperature when the prey are highly mobile (Vucic-Pestic et al 2011).…”

Abstract. Insect mutualisms can have disproportionately large impacts on local arthropod and plant communities and their responses to climatic change. The objective of this study was to determine if the presence of insect mutualisms affects host plant and herbivore responses to warming. Using open-top warming chambers at Harvard Forest, Massachusetts, USA, we manipulated temperature and presence of ants and Chaitophorus populicola aphids on Populus tremuloides host plants and monitored ant attendance and persistence of C. populicola, predator abundance, plant stress, and abundance of Myzus persicae, a pest aphid that colonized plants during the experiment. We found that, regardless of warming, C. populicola persistence was higher when tended by ants, and some ant species increased aphid persistence more than others. Warming had negligible direct but strong indirect effects on plant stress. Plant stress decreased with warming only when both ants and C. populicola aphids were present and engaged in mutualism. Plant stress was increased by warming-induced reductions in predator abundance and increases in M. persicae aphid abundance. Altogether, these findings suggest that insect mutualisms could buffer the effects of warming on specialist herbivores and plants, but when mutualisms are not intact, the direct effects of warming on predators and generalist herbivores yield strong indirect effects of warming on plants.
