Habitat manipulation in agroecosystems can influence predator–prey interactions. In this study, we collected foliar predators from field potato plots with different mulch treatments and assayed them for DNA of the target prey, Leptinotarsa decemlineata (Say), using species-specific primers. Concurrently, L. decemlineata larval abundance and plant damage were recorded from the same plots. Predat...

Zusammenfassung Zu Beginn einer Massenvermehrung des Kartoffelkäfers sind in der Regel nur eine begrenzte Anzahl Kartoffelpflanzen im Feld befallen (Befallsherde). Bei schaderregerbezogenen gezielten Insektizidspritzung würden Abhängigkeit von Bekämpfungsschwellen diese Befallsherde behandelt, was zu erheblichen Reduzierung Insektizideinsatzes führen könnte. Voraussetzung ist ein lückenloses Mo...

Plants respond to pest attack, among other mechanisms, by producing specific proteins with insecticidal properties. Proteins toxic effects on insects have also been discovered in many organisms, especially fungi and bacteria. Due their biological function, represent an important potential the development of more environmentally friendly plant protection methods. Increasing knowledge about mode ...

Field trials were conducted in 2003 and 2004 to assess the effectiveness of novaluron (Rimon 10EC), a benzoylphenyl urea chitin synthesis inhibitor, for Colorado potato beetle, Leptinotarsa decemlineata (Say), management on potato. Foliar applications of novaluron did not significantly reduce numbers of L. decemlineata adults, egg masses, or first instar larvae, but second–fourth instars were g...

Plants respond adaptively to herbivore stress in order maintain fitness. Upon attack, plants emit blends of volatile organic compounds (VOCs) that differ from those are constitutively emitted. These defense responses typically specific the identity attacking and often linked herbivore's feeding guild (e.g. chewing, phloem-feeding). Herbivores use plant volatiles locate suitable host changes emi...

In this study conducted in 2020, the resistance of Leptinotarsa decemlineata Say, 1824 (Coleoptera: Chrysomelidae) populations collected from Karapınar, Çumra, Seydişehir, Güneysınır and Doğanhisar Districts Konya Province, Turkey to lambda-cyhalothrin imidacloprid was investigated. Insecticides were applied topically fourth instar larvae. addition, synergistic efficiency diatomaceous earth (DE...

The study was carried out between the years 2019-2020 in order to determine Chrysomelidae species and their host plants vegetable fields of greenhouses, gardens, open located central district Burdur province. As a result 366 samples examined; 18 belonging 5 genera from Galerucinae subfamily, 2 Chrysomelinae 1 Criocerinae subfamily were identified. Information about local distributions added for...
