Hatching behavior of potato cyst nematodes from the canary islands.
The present work investigated early hatching differences in naturally occuring field populations and newly reared populations of potato cyst nematodes from the Canary Islands. Hatching behavior of the two species appears to be distinct, with more juveniles hatched from G. pallida that hatch earlier and over a shorter time than G. rostochiensis. The hatching rate of 3-year-old PCN populations wa...

متن کاملThe effect of mycorrhizal fungi on the hatch of potato cyst nematodes
In the presence of potato plants cv. Golden Wonder, Globodera pallida exhibited delayed in-soil hatch compared to that of G. rostochiensis, with significantly fewer G. pallida second-stage juvenile nematodes hatching in the first two weeks, though the difference disappeared after four weeks. Inoculation of potato plants with arbuscular mycorrhizal fungi eliminated this delay in G. pallida hatch...
متن کاملWorldwide distribution of potato-cyst nematodes and their importance in crop production.
The potato-cyst nematodes Heterodera rostochiensis and H. pallida are important pathogens of potatoes, a basic food crop. When soil populations of either species are high, potato yields are often less than the seed planted. Apparently, these nematodes originated in the Andean mountains of South America, the home of the potato. One or both species have spread from this region to approximately 47...
متن کاملIdentification and Characterisation of a Hyper-Variable Apoplastic Effector Gene Family of the Potato Cyst Nematodes
Sedentary endoparasitic nematodes are obligate biotrophs that modify host root tissues, using a suite of effector proteins to create and maintain a feeding site that is their sole source of nutrition. Using assumptions about the characteristics of genes involved in plant-nematode biotrophic interactions to inform the identification strategy, we provide a description and characterisation of a no...
