The nun moth Lymantria monacha L. and pine lappet moth Dendrolimus pini L. belong to the insects occurring in cyclical outbreak threatening the sustainability of Scots pine Pinus sylvestris L. forests. The populations of both species are reduced in aerial treatments carried out in Poland on thousands of hectares. Therefore there still is a need to implement to the forest practice insecticides that...
Repeating outbreaks of the Scots pine pests, effecting in stands damages, are the most important problems of forest protection. In extreme cases they pose a real threat to the stability of stands. Naturally occurring entomopathogenic nematodes are important regulatory factors in insect populations. Many species are employed as biological agents to control the insect pests. The objectives of this research...
Root−feeding insects are an increasingly studied group of herbivores, whose impact on plant productivity and are some of the most damaging forest pests in Europe. Due to the mass feeding on the roots of seedlings and older trees in young plantation and stands, Melolonthinae larvae are classified as pests, which are the most dangerous on the land dedicated to afforestation. The research was located...
Bats have a set of features that make them very effective insects predators, thus they can potentially play an important role as a biological pest control agent in forests. The active flight ability, nocturnal lifestyle, high level of metabolism and a lack of a significant threat from predators make bats the most important predators of insects active in the evening and at night. All bats species noted...
In response to the information published in “Forest Research Papers” (vol. 77(4), 2016), regarding the problem of the European spruce bark beetle Ips typographus (L.) in the Białowieża Forest, we present our viewpoint on this issue. The role of the European spruce bark beetle in the Białowieża Forest is discussed based on experience gained in Europe’s forests. We present the effects of I. typographus...
The Sustainable Use Directive (2009/128/EC) establishes a framework for European Community action to achieve the sustainable use of pesticides imposed restrictions in agro−aviation pesticides application. As a result of the creation of buffer zones, part of the endangered area must be excluded from spraying and the area will be fragmented. This article evaluated the impact of the size, shape and distance...
This article studies the effect of light and high temperature on various parameters describing the growth and development of bird cherry ermine moth (Yponomeuta evonymellus L.) – the main pest of bird cherry (Prunus padus L.). We found that light significantly influences the moth masses and dynamics of their development. Moths developed from larvae feeding on leaves growing in full light conditions...
The study evaluates the antifeedant activity of rutin and quercetin (flavonoids of buckwheat Fagopyrum esculentum) and the extract from the leaves of black alder Alnus glutinosa on the development and the extent of damage caused by the beetles of cockchafer Melolontha melolontha in laboratory and semi−field conditions. We found increased mortality and decreased intensity of beetle feeding on the Quercus...
