“…However, research has shown that seed treatments may also pose a risk to beneficial organisms via less obvious routes of exposure, causing both lethal and sublethal effects (Li et al 2012). Sublethal effects, in particular, are easily overlooked and yet may have considerable impact on natural enemy population dynamics and the level of ecosystem services contributed by these insects (Desneux et al 2007;He et al 2012;Biondi et al 2012a;Biondi et al 2013;Planes et al 2013) Systemic insecticides are characterized by low lipophilicity, typically exhibiting an octanol-water partition coefficient (log Poct) below 40 (Cloyd and Bethke 2011) which facilitates their translocation in plant tissues. Residues of such insecticides can be translocated to various plant parts (Dively and Kamel 2012;Goulson 2013).…”

“…Heavily infested fruit may be downgraded in the packinghouse and, if population levels are high, trees can be seriously damaged. Aphytis melinus effectiveness could depend on the scale careful monitoring, on the use of selective insecticides to control other pests (Grafton-Cardwell et al, 2006;Suma et al, 2009;Planes et al, 2012;Vanaclocha et al, 2012), on the host instars available and their size (Luck & Podoler, 1985;Pekas et al, 2010a), on ant activity (James et al, 1997;Pekas et al, 2010b), on the fitness of the released insects (Vasquez & Morse, 2012) or on environmental conditions (DeBach & Sisojevic, 1960).…”

Abstract. The efficacy of natural enemies in controlling pests under field conditions is largely correlated with their capacity to spread within infested crops. In this study the spatial dispersal of the California red scale parasitoid Aphytis melinus DeBach (Hymenoptera: Aphelinidae) was evaluated in the field after augmentative releases. The experiment was conducted in 2007 in six 1-ha plots in a Sicilian citrus orchard under integrated pest management. A total of 180,000 A. melinus adults was released in each of three plots and the other plots were left as untreated control. The flight range of the parasitoid was evaluated, for 35 days after the release, on 16 trees per each plot, located at 20 and 40 m from the central release point using yellow sticky traps activated with Aonidiella aurantii (Maskell) (Hemiptera: Diaspididae) sexual pheromone and by monitoring the percentage parasitism of the scale on fruits and twigs. The effects of the distance from the release point and density of susceptible stages of host on parasitoid dispersal were evaluated. The number of wasps captured during the whole trial was greater in the traps located 20 m from the release point than in those at 40 m and in the control plots. Aphytis melinus dispersed over distances less than 40 m based on both the lower percentage parasitism and numbers captured recorded at distances of 40 m. The results are discussed in the context of the biological control of California red scale in citrus orchards by means of wasp releases. In particular, the release points should be no more than 40 m apart for a quick and homogeneous colonization of the area treated.

“…Chlorpyrifos, an organophosphate insecticide, is one of the most-widely used insecticides for pest control in citrus against hemipterans (scales and aphids) and thrips (Morse & Grafton-Cardwell 2012a;NavarroCampos et al 2012b;Planes et al 2013). It is used against the latter because of its fast-acting effect.…”
