Dickeya dianthicola (Samson) is an important pathogen causing blackleg disease of potato. Previous work suggested that insects might vector species of Pectobacteriaceae between plants but no conclusive work has confirmed this. Green peach aphids (Myzus persicae Sulzer) and Colorado potato beetles (Leptinotarsa decemlineata Say) are aggressive potato pests and related to known vectors of several […]

Two-spotted spider mite, Tetranychus urticae Koch, is a ubiquitous and highly polyphagous plant pest with a worldwide distribution. Diapause is essential for its survival in the areas with unfavorable seasonal conditions. We investigated whether female mites overwintering close to the soil surface may be adapted to seasonal flooding. Among the tested mites diapausing on leaf

Colorado potato beetle, Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae), is an oligophagous herbivore that feeds on several plant species in the family Solanaceae. Cannibalism is common in this species and accounts for a significant part of natural field mortality.We investigated effects of feeding on potato (Solanum tuberosum L., preferred host), tomato (Solanum lycopersicum L., nonpreferred host),

 Decline in soil health is a serious worldwide problem that decreases complexity and stability of agricultural ecosystems, commonly making them more prone to outbreaks of herbivorous insect pests. Potato (Solanum tuberosum L., Solanaceae) and onion (Allium cepa L., Amaryllidaceae) production is currently characterized by high soil disturbance and heavy reliance on synthetic inputs, including insecticides. Evidence suggests

Black soldier fly, Hermetia illucens (L.) (Diptera: Stratiomyidae) can be used for recycling a wide variety of organic wastes. However, these wastes are also suitable for colonisation by pest fly species, including the blow fly Lucilia sericata (Meigen) (Diptera: Calliphoridae), and by pathogenic microorganisms. We tested effects of the presence of black soldier fly larvae (BSFL) on recruitment and

Black soldier flies, Hermetia illucens (L.), consume decaying organic materials at the larval stage and can be used for recycling a variety of biogenic wastes into value-added products. Black soldier flies are normally found in subtropical and warm temperate regions. Cold temperatures may prevent their establishment in colder areas, thus alleviating a concern of their becoming an

Impaired expression of the beta and delta isoforms of vacuolar processing enzymes compromise the basal defenses of Arabidopsis thaliana against the phloem-feeding insect Myzus persicae. Acta Physiologiae Plantarum 39: 233. https://doi.org/10.1007/s11738-017-2529-z

While the functions of vacuolar processing enzymes (VPE) in plant responses to pathogens are now better established, their possible roles against insect herbivores need validation. Inspired by an observation that betaVPE and deltaVPE represent the most highly upregulated transcripts in leaves of Solanum bulbocastanum and its backcross progenies that were highly resistant to the phloem-feeding

Cannibalism, or intraspecific predation, can play a major role in changing individual fitness and population processes. In insects, cannibalism frequently occurs across life stages, with cannibals consuming a smaller or more vulnerable stage. Predation of adult insects on one another is considered to be uncommon. We investigated adult cannibalism in the Colorado potato beetle, Leptinotarsa

The Colorado potato beetle is an important pest of solanaceous plants in the Northern Hemisphere. Better understanding of its physiological responses to temperature stress and their interactions with still-prevalent chemical control has important implications for the management of this insect. We measured mortality and expression of the Hsp70 heat shock proteins in the Colorado potato

Colorado potato beetle, Leptinotarsa decemlineata (Say) is a major pest of potatoes in North America, Europe, and parts of Asia. It adapts quickly to adverse environments, thereby limiting the longevity of control strategies. Better understanding of variability among geographically isolated populations of this insect might create an opportunity to customize control techniques for local conditions. We investigated
