The invention relates to the use of an organometallic coordination complex or its phytopharmaceutically acceptable salt of a M.sup.m+ metal and of at least one L ligand, where M.sup.m+ is a transition metal having an oxidation number m, L is a ligand of general formula (VII) or its anion, wherein R.sup.1 is selected from the group consisting of oxygen, mono or polycyclic alkyl, naphthalene residue, anthracene residue and their hydroxylated or ketone derivatives; R.sup.2 and R.sup.3 are identical or different and are selected independently of each other from hydrogen, halogen, a hydroxyl group, an alkoxy group, a linear or branched alkyl group, a cycloalkyl group or R.sup.2 and R.sup.3 together forming a benzene derivative; R.sup.6, R.sup.7 and R.sup.8 are identical or different and independently of each other are selected from hydrogen, a hydroxyl group, an alkoxy group, a linear or branched alkyl group, a cycloalkyl group, a phenyl group, an aryl group in the treatment of Xylella fastidiosa in a plant. The invention also concerns the use of the compound of formula (VII) in the treatment of Xylella fastidiosa in a plant, also in combination with the organometallic coordination complex. Advantageously, the invention concerns the treatment of olive trees.

Disclosed is a composition of volatile and less-volatile pheromone components that can be used alone or in combination with other compounds to attract and/or arrest bed bugs of both sexes and all developmental stages. This blend can be used to bait traps that are effective in capturing bed bugs in infested premises or can be combined with a pesticide that is lethal to bed bugs.
