Evaluation of drone system for thinning operations–a case study in Sweden
International Transactions in Operational Research, EarlyView.Abstract Thinning operations in forestry typically involve a two‐machine system (TMS) with a harvester and a forwarder. Its productivity in different forest conditions is well documented. To date, drones have been used for data collection and surveillance but not as an alternative to a TMS.

Journal of Applied Entomology, EarlyView.ABSTRACT Biological control in high tunnel systems can be optimised by matching predator species to seasonal environmental conditions. We evaluated the predatory efficacy of syrphid flies (Toxomerus marginatus (Say), Eupeodes americanus (Fabricius)) and lacewings (Chrysoperla carnea (Stephens), Chrysoperla rufilabris (Burmeister)) across laboratory ...

A History of the Eastern Larch Beetle, \u3ci\u3eDendroctonus Simplex\u3c/i\u3e (Coleoptera: Scolytidae), in North America [PDF]
, 2017 The eastern larch beetle, Dendroctonus simplex, is reputedly a secondary pest but may attack and kill tamarack and ornamental larches throughout Canada, the northeastern United Stales, and Alaska. Isolated infestations of this pest have been reported for

Journal of Applied Entomology, EarlyView.ABSTRACT Norway spruce will likely remain an important tree species in Europe over the next few decades despite efforts to transform forests and reduce its distribution range more to its natural range. Consequently, Ips typographus will remain one of the most relevant forest pests the management of which will become increasingly challenging due to ...

Journal of Applied Entomology, EarlyView.ABSTRACT Invasive species pose a serious threat to biodiversity and result in significant economic costs. Although much effort is devoted to understanding invasive processes, some aspects are poorly understood, such as the early stages of invasions and the reasons for invasion failure.

Entomogenic Climate Change [PDF]
, 2008 Rapidly expanding insect populations, deforestation, and global climate change threaten to destabilize key planetary carbon pools, especially the Earth's forests which link the micro-ecology of insect infestation to climate.
