Loss of stored plant products due to insect infestation is a problem that is likely to increase with global warming. Improved storage under hermetic conditions in oxygen deficiency can prevent or control infestation and preserve product quality. Oxygen levels in hermetic storage decrease due to different factors, one of which is the oxygen consumpt...

Insects in grain can cause serious problems, not only because they feed on the grains. Mass reproduction also causes additional moisture and heat due to the insects' metabolism. This leads to favourable conditions for moulds, which can cause major losses and the formation of mycotoxins. It is therefore important to detect and treat an infestation a...

Ein nachhaltige Möglichkeit des Vorratsschutzes ist die Bekämpfung der Motten und Käfer im Getreidelager durch die Zugabe natürlich vorkommender Gegenspieler der Fraßinsekten.

The insecticidal effect of two zeolite formulations was tested on wheat against adults of Lepinotus reticulatus Enderlein, Liposcelis decolor (Pearman), Acarus siro L. and Stegobium paniceum (L.). The zeolites were tested at four dose rates, i.e., 50, 100, 500 and 1000 ppm (mg per kg of wheat). The bioassays were conducted under laboratory conditio...

Early detection of insect infestation in grain storage facilities is of great importance to avoid losses and massive pest spreading. Acoustics can be used to detect feeding and movement of insects. However, so far in cereals this only worked on close range due to the low level of insect sounds and the sound insulation effects of grain. To improve t...

Studies on the effects of offshore wind farm construction on marine life have focused on behavioral reactions in porpoises and seals (Thomsen et al. 2006). The effects on fish have only very recently come into the focus of scientists, regulators, and stakeholders (Popper and Hastings 2009). Pile-driving noise during construction is of particular co...

There is an urgent need to obtain information on the effects of underwater sound on marine fish due to imminent policy drivers, e.g., the European Union Marine Strategy Framework Directive, on one hand and the increasingly noisy activities in the marine environment on the other. Yet studying the influence of sound, particularly on the behavior of f...

The effect of anthropogenic underwater sound on fish has become an important environmental issue. Pile-driving noise during construction is of particular concern as the very high sound pressure levels could potentially prevent fish from reaching breeding or spawning sites, finding food, and acoustically locating mates. This could result in long-ter...

The growing number of planned or already built offshore wind farms will add to the anthropogenic noise level in the sea and is likely to influence marine animals such as fish. Operational noise of wind turbines is permanently emitted through the pile into the water, with the strongest emission up to a frequency of 500 Hz. Sound levels of up to 140...

Anthropogenic sound in the sea, such as noise emitted by offshore wind farms, is an increasing problem and the influence of this sound on fish needs to be understood. Behavioural experiments were carried out to examine the reaction of cod (Gadus morhua) and plaice (Pleuronectes platessa) to low frequency sound. An annular concrete tank of 10 m in d...

Anthropogenic sound in the sea is an increasing problem and more knowledge on the influence of sound on fish needs to be collected. For this reason experiments are carried out in an experimental tank 10 m in diameter to examine the reaction of juvenile and adult cod and plaice to sound. Pure tones from the frequency range of offshore wind turbines...

General information is given on the Coleoptera collection of the Museum für Naturkunde in Berlin (MNHUB) comprising six million specimens and its “Historical Collection” very rich in types. The Ciidae (= Cisidae, = Cioidae) collection of the MNHUB is newly arranged. Data on supraspecific taxa and all represented nominal taxa of the species group an...
