W wielu miejscach na świecie dramatycznie zmniejsza się liczebność i różnorodność stawonogów, w tym owadów. Liczba owadów w ciągu ostatnich 25 lat spadła o 76% w obszarach chronionych w Niemczech. W ciągu ostatnich 35 lat liczba owadów naziemnych w lesie tropikalnym w Porto Rico zmniejszyła się o 98%. Biomasa owadów na Ziemi ubywa w tempie 2,5% rocznie.

W artykule oceniono potencjał wierzby hodowanej na cele energetyczne jako środowiska życia entomofauny. Badanie liczebności i bioróżnorodności owadów (zarówno drapieżników jak i roślinożernych) przeprowadzono na plantacji w Polowej Stacji Doświadczalnej IOR-PIB w Winnej Górze w latach 2009 i 2010. Zebrano próbę 1840 owadów należących do 7 rzędów i 27 rodzin. Najliczniej reprezentowane były chrząszcze...
In the years 20092010 there were research on chosen sites in Świętokrzyskie Mountains and near Suchedniów Plateau, to check if dragonflies show strong habitat preferences on this area. Moreover, it was tested which species live there and if protected areas are correlated with higher diversity of these insects. It was found out that protected habitat does not mean more species of dragonflies nor conservation...
Biodiversity is an essential component to preserve the stability of life sustaining structures. Creating new habitats, such as perennial bioenergy plant plantations, may help to maintain it. This includes short rotation willow. Willow plantations present an excellent environment for a large number of species of plants and animals, together with beneficial insects.
