[effect of the length of the stay of the male on the reproduction of the olive psylla euphyllura olivina costa (homoptera, psyllidae)].	we have studied, in euphyllura olivina costa, 1839, the incidence that the absence or presence of males can have on the fecundity of females their longevity, the duration of spawning and other biotic parameters... so we have pointed out that: in all the cases, from beginning of experimental infestations of olive--tree sprouts to the beginning of eggs releasing, there is a preovipositional time of very variable duration. virgins, isolated from imago emergence, have a trifling spawning and the egg ...	2006	6544053
olive trees protected from the olive bark beetle, phloeotribus scarabaeoides (bernard 1788) (coleoptera, curculionidae, scolytinae) with a pyrethroid insecticide: effect on the insect community of the olive grove.	field studies were performed in two successive years, 2005 and 2006, in different olive groves of the province of granada (south-eastern spain) by spraying olive trees (olea europaea) with a pyrethroid insecticide, deltamethrin, for the control of the olive bark beetle phloeotribus scarabaeoides (bernard 1788) (coleoptera, curculionidae, scolytinae). three olive groves received each year three treatments in june consisting of water (control) and two insecticide doses, which were halved the secon ...	2010	20413141
effect of non-crop vegetation types on conservation biological control of pests in olive groves.	conservation biological control (cbc) is an environmentally sound potential alternative to the use of chemical insecticides. it involves modifications of the environment to promote natural enemy activity on pests. despite many cbc studies increasing abundance of natural enemies, there are far fewer demonstrations of reduced pest density and very little work has been conducted in olive crops. in this study we investigated the effects of four forms of non-crop vegetation on the abundance of two im ...	2013	23904994
is ground cover vegetation an effective biological control enhancement strategy against olive pests?	ground cover vegetation is often added or allowed to generate to promote conservation biological control, especially in perennial crops. nevertheless, there is inconsistent evidence of its effectiveness, with studies reporting positive, nil or negative effects on pest control. this might arise from differences between studies at the local scale (e.g. orchard management and land use history), the landscape context (e.g. presence of patches of natural or semi-natural vegetation near the focal orch ...	2015	25646778
