| a genetically homogenous population of fusarium circinatum causes pitch canker of pinus radiata in the basque country, spain. | pitch canker, caused by fusarium circinatum, is a destructive disease of pinus species and has recently been shown to represent a substantial threat to natural and commercial forests in northern spain. the genetic diversity of f. circinatum in the basque country of spain was assessed by characterising 96 isolates based on vegetative compatibility groups (vcgs), mating type assays, polymorphic dna-markers and amplified fragment length polymorphism (aflp) analyses. for this purpose, f. circinatum ... | 2011 | 21354535 |
| electrophysiological and behavioural responses of pityophthorus pubescens (coleoptera: scolytinae) to (e,e)-α-farnesene, (r)-(+)-limonene and (s)-(-)-verbenone in pinus radiata (pinaceae) stands in northern spain. | some twig beetles in the genus pityophthorus (coleoptera: scolytinae) may vector pitch canker disease fusarium circinatum (niremberg & o'donnell) of pinus spp. (pinaceae). because pityophthorus pubescens (marsh.) has been found to be associated with f. circinatum in the basque country (northern spain), various experiments were conducted to assess the beetle's behavioural responses to (e, e)-α-farnesene, (r)-(+)-limonene and (s)-(-)-verbenone to develop a potential inhibitor to host attraction. t ... | 2013 | 22764125 |
