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...

Acoustic detection of stored-product insects

Post-harvest management constraints are economically significant in Africa for a broad range of commodities, resulting in a substantial negative impact on food security and livelihoods. Rhyzopertha dominica (Fabricius) (Coleoptera: Bostrichidae) coexists with Sitophilus oryzae (L.) (Coleoptera: Dryophthoridae) – they infest stored cereal grains, es...

Stored-product protection, museum environments as well as protection of materials are growing fields of application of macro-organisms for biological control in Central Europe during the last 25 years.

Post-harvest losses are economically significant in Ghana for a broad range of commodities, resulting in a substantial negative impact on food security and livelihoods. Maize grains are the main food crops that provide staple diet for the majority of the population. A nation-wide survey was conducted in the three different geographical zones of Gh...

Parasitoids can suppress populations of their host and thus play a primary role in Integrated Pest Management. We studied foraging cues in Holepyris sylvanidis (Hymenoptera: Bethylidae), a larval parasitoid of Tribolium species, in a four-chamber olfactometer. H. sylvanidis is reported as a cosmopolitan parasitoid of Coleopteran including two major...

The Convention on Biological Diversity (CBD) commits its 196 nation parties to conserve biological diversity, use its components sustainably, and share fairly and equitably the benefits from the utilization of genetic resources. The last of these objectives was further codified in the Convention's Nagoya Protocol (NP), which came into effect in 201...

Previous reviews on biological control of stored-product pests published during the last 30 years reported results of laboratory experiments, collected examples for practical application in grain stores and in processing companies, and summarized the literature on the relevant control agents dating back to the beginning of the last century.

Aus diesem Grund gehören Textilschädlinge, wie Teppichkäfer, Pelzkäfer, Kleider- u. Pelzmotte, oder Holzschädlinge, wie Nagekäfer, Splintholzkäfer und Hausbock, sowie Papierschädlinge...

The importance of eco-friendly solutions to control pests is due to the pressure deriving from consumers and politics. Scientists are presenting solutions to match both the legal requirements and the need of industries producing organic food. Although Bethylidae have been less studied if compared to parasitoids belonging to other families, they rep...

The aim of the present study was to evaluate two species of egg parasitoids under laboratory conditions for biological control of the Indian meal moth Plodia interpunctella, an emerging stored product pest in bulk grain.

Häufig finden sich in Museen, Sammlungen und historischen Gebäuden nicht nur Schäden, sondern auch tote oder lebende Organismen, die potenziell für die beobachteten Probleme verantwortlich sein könnten. Doch handelt es sich bei den Tierchen tatsächlich um die Schädlinge? Im Sommer dringen mitunter auch harmlose Freilandtiere in Räume ein. Diese Fra...

Lack of syntheses of knowledge on immature stages of insects impedes accurate understanding of their diversity, biology and evolution. Literature describing known immature stages of case-bearing chrysomelids is catalogued, i.e., 358 species of Cryptocephalinae Gyllenhal and 13 species of Lamprosomatinae Lacordaire. The catalogue covers the world fa...

Protection of stored plant products (products of plant origin in an unprocessed state or having undergone only simple preparation, such as milling, drying or pressing, but excluding plants) tries to avoid losses in mass and quality. One of the most important ways of protecting plants and plant products against harmful organisms is the use of plant...

Stored product insects infest stored grain, flour, dry herbs, dry fruits, nuts, and many other dry stored products of plant origin. Beside these stored product pests, insects with different feeding habits are associated with stored products, e.g. mould feeders, saprophagous species, predators or parasitoids. In this study, with the help of reviews...
