Abstract The present work aimed to determine the insecticidal effects of three selected essential oils (EOs) Pogostemon cablin , Thymus vulgaris and Citrus aurantifolia against insect species Melolontha melolontha Halyomorpha halys Pyrrhocoris apterus . EO P. showed very strong M. when it inhibited by more than 50% at concentrations 50–6.25%. Against H. also 50–12.5%. activity was significantly...

The invasive pentatomid true bug Halyomorpha halys is reported for the first time from German state of Hamburg, along with records several other locations in Northern Germany. Specimens collected by scientists were evaluated citizen science platforms. DNA barcode sequences H. specimens Hamburg 42 species across world a haplotype network analysis demonstrating that all studied had H3. present di...
