Neuropteroidea and Mecoptera of the Bohemian Forest
Zelený, Jiří
General information is given on the current status of knowledge of Neuropteroidea and Mecoptera in the Czech Bohemian Forest (Šumava Mts.), especially in peatbogs. In the Bohemian Forest, 2 species Megaloptera, 6 species of Raphidioptera, 48 species of Neuroptera (Coniopterygidae 10 species, Osmylidae 1 species, Sisyridae 2 species, Hemerobiidae 22 species, Chrysopidae 12 species and Myrmeleontidae 1 species) and 4 species of Mecoptera are known. The most common species are: Hemerobius pini, Conwentzia pineticola, Coniopteryx pygmaea Wesmaelius quadrifasciatus and Chrysoperla carnea.The species importatnt for the nature conservation and biological diversity are: Phaeostigma major, Puncha ratzeburgi, Aleuropteryx loewii, Coniopteryx esbenpeterseni, Parasemidalis fuscipennis, Osmylus fulvicephalus, Sisyra terminalis, Wesmaelius ravus, Micromus lanosus, Sympherobius pellucidus a Myrmeleon formicarius.

Updated list of stoneflies (Insecta, Plecoptera) of the Šumava National Park and Protected Landscape Area with regard to their species protection
Soldán, Tomáš
Update list of Plecoptera of the area in question consists of 75 species,18 genera and 7 families of the order including 5 species the txonomic status of which is unclear and respective historical records seem to be doubtful. Based on recent data,5 species, namely Brachyptera monilicornis (Pictet, 1841), Capnopsis schilleri (Rostock, 1892),Rhabdiopteryx acuminata Klapálek,1905,Nemoura sciurus Aubert, 1949 a Nemoura cf. babiagorensis Sowa,1964,are recorded from the Bohemian part of the mountains for the first time. Long-term data originating from the 1950´s of the past century enable to evaluate the status from their protection point of view (red list):3 species are extinct within the whole Czech Republic,5 species are extinct or missing in the Bohemian Forest (=Šumava Mts.) for more then 20 yearch,2 are critically endangered,6 endangered,7 vulnerable and 8 species are near threatened. Further 6 species show data deficiency and remaining 36 species still do not require any treatment.

Bark beetles (Scolytidae, Coleoptera) on spruce in the Bohemian Forest
Zelený, Jiří ; Doležal, Petr
The article summarized part of data, that were obtained during 6 years lasting research focused on bark beetles and their natural enemies in the Bohemian Forest (Šumava Mts). 26 species of bark beetles were collected from spruce samples that were brought from Modrava, Srní, Kvilda, Borová Lada etc. Despite many abundant pest species like Ips typographus, Ips amitinus, Pityogenes chalcographus a Polygraphus polygraphus, also three uncommon species were collected: Pityogenes conjunctus, Pityophthorus micrographus a Xyloterus laeve. These three species may have importance for nature conservation.

Natural enemies of bark beertle Ips typographus
Zelený, Jiří ; Lozan, Aurel
Totally 49 species of predators and 22 species of parasitoids are contributing to the population regulation of bark beetles, namely Ips typohraphus, in spruce forest of the Czech republic. The most encountered predators of bark beetles in our samples during 1998-2003 were: Thanasimus formicarius (Coleoptera), Medetera signaticornis and Lonchaea bruggueri (Diptera): hymenopteran parasitoids: Coeloides bostrichorum, Dendrosoter middendorfii, Cosmophorus klugii (Braconidae): Rhopalicus tutela, Roptrocerus xylophagorum, Tomicobia seitneri a Dinotiscus eupterus (Pteromalidae). The siricid wasp Ibalia leucospoides (Cynipoidea, Ibaliidae) is recorded too.

Leaf-spinning moths (Lepidoptera) feeding on Vaccinium uliginosum L. along an ecological gradient of the Šumava peat bogs
Spitzer, Karel ; Bezděk, Aleš ; Jaroš, Josef
The leaf-spinning moths (Lepidoptera: Tortricidae, Gelechiidae, Chimabachidae and Geometridae) associated with the boreal plant Vaccinium uliginosum L. were investigated in two different peat bogs (Mrtvý Luh near Volary and Chalupská Slať near Borová Lada). During four years (1998-2001) of collecting leaf spinnings, 19 species of moths were recorded from both peat bogs. The occurence of moths was structured along a distinct mesoclimatic gradient. Species closely associated with peat bogs (tyrphobiontic and tyrphophilous taxa) were found to be most abundant in treeless centers of both bogs in comparisonwith marginal parts.
