DOI: 10.1002/ps.6957
Abstract: Abstract BACKGROUND Plant resistance to insects can be reduced by crop domestication which means their wild ancestors could provide novel sources of resistance. Thus, crossing wild ancestors with domesticated crops can potentially enhance their resistance… read more here.

DOI: 10.1002/ps.7192
Abstract: BACKGROUND Insect neuropeptides control essential physiological metabolic activities. In our previous studies, Capability/CAP2b (PK/CAPA) analog 1895 applied alone or as a combination of CAPA analogs (1895+2315) was reported to decrease aphid fitness. While this was… read more here.

DOI: 10.1007/s10340-017-0941-1
Abstract: Genetically modified (GM) plants may show unintended differences compared to the original varieties, due to the modification process. Such differences might in some cases affect non-target organisms linked to the crop into an agro-ecosystem. In… read more here.
