1 The attractiveness of pitfall traps baited with a synthetic host volatile attractant to colonizing adult Colorado potato beetle, Leptinotarsa decemlineata (Say) was evaluated in a field setting. 2 Significantly more postdiapause, colonizing adult L. decemlineata were captured in baited than unbaited pitfall traps. 3 The potential for this synthetic kairomone to enhance the efficacy of trap cr...

Aim. The Colorado potato beetle population is characterized by a high degree of polymorphism. This provides level adaptability to the most diverse distribution conditions. aim study variability pattern Leptinotarsa decemlineata pronotum in June 2021 and 2022. Methods. analysis phenotypic L. Kamianka-Buzka city based on studying presence or absence certain phens, their number placement according...

The joint action of a plant parasitic nematode, Pratylenchus penetrans (root-lesion nematode), and an insect defoliator, Leptinotarsa decemlineata (Colorado potato beetle), on growth, development, and yield of Solanum tuberosum cv. Superior was studied in the field. Three population densities of P. penetrans were superimposed on each of three population levels of L. decemlineata. The major impa...

Results of laboratory experiments are reported that tested the effects of five chitin synthesis inhibitors, diflubenzuron, cyromazine, lufenuron, hexaflumuron and triflumuron. on second instars of the Colorado potato beetle, Leptinotarsa decemlineata (Say) (Coleoptera: Crysomelidae), originally collected from potato fields of Bostanabaad, a town 66 km southeast of Tabriz, Iran. In bioassays, th...

The aim of this study was to determine the effects water extracts tarragon (Artemisia dracunculus L.) on feeding intensity, mortality, and weight gain selected pests, i.e., adult pea leaf weevils (Sitona lineatus L.), nymphs, wingless females black bean aphids (Aphis fabae Scop.), L2 L4 larvae Colorado potato beetle (Leptinotarsa decemlineata Say). In addition, effect voracity non-target organi...
