Relative attractiveness of colour traps to pear psylla in relation to seasonal changes in pear phenology

Monitoring of pear psylla (Cacopsylla pyricola (Förster), Hemiptera: Psyllidae) prior to spring bud break could aid in predicting the size of subsequent spring populations and lead to improved proactive management decisions. Yellow traps are commonly used to monitor hemipteran pests including pear psylla, but very little is known regarding seasonal changes in attractiveness of yellow traps or r...

The PEAR proposition.

For more than a quarter century, the Princeton Engineering Anomalies Research (PEAR) laboratory has engaged in a broad range of experiments on consciousness-related physical anomalies and has proposed a corresponding selection of theoretical models that have combined to illuminate the fundamental nature of the provocative phenomena that emerge. Productive pursuit of this topic has inescapably i...

Draft Genome Sequence of Erwinia billingiae OSU19-1, Isolated from a Pear Tree Canker

Plant-associated Erwinia include pathogenic and nonpathogenic species. We report the 5.6-Mb genome sequence of Erwinia billingiae OSU19-1, isolated from a canker on a pear tree inoculated with Erwinia amylovora. OSU19-1 and a closely related European isolate, E. billingiae Eb661(T), share many similarities including 40 kb of plasmid sequence.

first characterization of apple scar skin viroid from apple and pear cultivars in iran and determination of genetic diversity

apple scar skin viroid (assvd) is one of the most destructive viroid diseases in pome fruits orchards which can cause significant economic losses. symptoms of this viroid including scaring, distortion and dappling were seen in some apple orchards in east-northern of iran. sampling was carried out from apple and pear orchards. the rna was extracted by silica capture method from leaves. assvd was...
