Abstract The effectiveness of phytophagous insect control systems depends on the accuracy chosen method monitoring their numbers and available information dynamics population number. As part automation processes collecting analyzing data biological activity pheromone preparations phytophage grapes Lobesia botrana Den. et Schiff., counting number pest butterflies glue inserts traps has been impr...

Analysis of apple tree phytosanitary state showed that the species composition phytophage mites is labile and subject to a constant shift share ratio. In 2012-2013, orchards Crimea were dominated by Amphytetranychus viennensis Zacher. Its in acarocomplex was 80%. Since 2014, ratio has changed towards prevalence Panonychus ulmi Koch. - 50%. With this, A. decreased 25.0%. some years there mass re...

Biological pest control methods are based on the use of preparations containing beneficial organisms, such as phytoceid mites, predatory insects, parasitoids, well entomopathogenic nematodes and bacteria, to limit size phytophage population level. According adopted concept phytosanitary optimization crop industry, there is a transition from total chemicals environmentally friendly plant protect...

This research is dedicated to solving an urgent problem associated with the large-scale destruction of taiga forests by Siberian silk moth (Dendrolimus sibiricus) outbreaks. The dynamics damage dark coniferous forest stands induced outbreaks in mid-altitude mountains were studied. A hypothesis was formulated based on fundamental influence orography phytophage’s dispersal within landscape, along...

This paper presents the results of multi-year research on adaptability winter wheat varieties to conditions foothill zone Central Caucasus. Characteristics such as ductility and stability were used assess for conformity cultivation conditions. Plant homeostaticity served indicator ontogenetic adaptability. Phenological observations reports carried out according state variety testing methodology...

Materials Methods The basis for work were materials collected flat mountainous parts Dagestan. Standard methods used: inspection search mass collection galls damage plants which larvae develop; rearing ima...

The complex of invasive species phytophagous insects that can adapt to novel living conditions is constantly increasing. ecological effect their vital activity in the new environment almost impossible predict. As a result, invasions undesirable economic sense are often observed. horse -chestnut leaf miner (Cameraria ohridella Deschka & Dimi?, 1986, Gracillariidae) one these problematic inva...

The phenomenon of metal hyperaccumulation by plants is often explained by a pathogen or herbivore defense hypothesis. However, some insects feeding on metal hyperaccumulating plants are adapted to the high level of metals in plant tissues. Former studies on species that feed on the leaves of Berkheya coddii Roessler 1958 (Asteraceae), a nickel-hyperaccumulating plant, demonstrated several prote...
