“…For example, sap‐sucking herbivores such as aphids were found to reduce the negative impact of ozone in plants of arugula ( Eruca sativa Mill), although ozone also affected aphids adversely (Menéndez et al . ). It is unclear however, whether the episodic exposure of plants to ozone affects the aphid performance indirectly through the plant.…”

1.Ozone is an increasing tropospheric contaminant of climate change. Exposure to ozone may affect the symbiotic relationship between plants and beneficial microorganisms. In particular, the herbivore resistance mechanism conferred by fungal endophytes (defensive mutualism) may be affected, as any of the ozone-triggered effects (such as elicitation of defence mechanisms against biotrophic fungi or oxidative stress in the apoplastic space) may target the symbiont. 2. Symbiotic and non-symbiotic Lolium multiflorum plants were exposed to ozone for two consecutive days (2 h per day), after which half were infested with 10 aphids (Rhopalosiphum padi). We measured variables related to performance of plants, the endophyte symbiont (alkaloids) and the herbivores. 3. Aphid populations were smaller on symbiotic plants than in non-symbiotic plants in lowozone conditions. However, this difference disappeared in exposed plants to high-ozone conditions. Under low-ozone conditions, structure of aphid populations on endophyte-symbiotic plants was characterized by a low number of nymphs and a high number of adults. This pattern was not observed with high-ozone exposure. Level of fungal alkaloids (lolines) was not affected by either ozone or herbivory. 4. Results indicate that ozone impairs the grass-endophyte symbiosis without affecting production of alkaloids generally linked with aphids' response to endophyte presence. Since neither plant biomass nor alkaloid level were affected by ozone, other ozone-mediated mechanisms at molecular or biochemical level may underlie plant-herbivore interaction mediated by fungal endophytes. Thus, the mechanism behind this effect must be determined in future experiments.

“…Although B. aphidicola has previously shown to be susceptible to heat stress and facultative endosymbionts may decrease the effect of this environmental stress (Montllor et al., ), these symbioses have not been studied in the context of ozone pollution. However, the effects of ozone pollution on aphid fecundity and aphid population growth (Awmack et al., ; Menéndez et al., ) resemble those of B. aphidicola symbiosis breakdown, reinforcing the importance of considering aphid‐endosymbiont association in the context of ozone pollution experiments.…”

“…Simultaneous exposure of plant and aphids to ozone may result in a complex interaction of effects, leading to variable results. Up to date, aphids have shown either positive, negative, or neutral effect response to ozone exposure (Warrington, 1989;Brown et al, 1992;Jackson, 1995;Holopainen & Kossi, 1998;Holopainen, 2002;Awmack et al, 2004;Men endez et al, 2010;Mondor et al, 2010). In most of these investigations, the exposure of aphids and plants to ozone was simultaneous and the explanation of the results was centred on plants nutritional quality change: premature senescence, nutrient relocation from ozone-damaged tissues, and premature lignification (Holopainen, 2002).…”

Most of our knowledge about the consequences of tropospheric ozone pollution on aphid–plant interaction assumes the absence of a direct effect of ozone on aphids. However, the biological effects of ozone encompass changes in reactive oxygen species signalling, oxidative stress accumulation, and the immune response of both plants and animals. The main objective of this work was to evaluate the direct effect of ozone on Metopolophium dirhodum (Walker) aphids (Hemiptera: Aphididae), linking mechanisms that operate at individual scale (oxidative stress parameters and aphid‐bacteria symbiosis persistence) with their consequences at population scale (mortality, dispersion, and population growth). Two experiments were conducted in open‐top chambers with three contrasting ozone exposure regimes (6 h at 0.5 ± 0.3, 50 ± 5, or 150 ± 10 p.p.b.) and artificial diets to evaluate the direct effect of ozone on aphids. Exposure of aphids to ozone increased insect mortality compared to the control treatment. However, the populations established from the surviving insects of each treatment increased similarly. Consistently, aphid symbiosis with Buchnera aphidicola Munson et al. (Proteobacteria) and Hamiltonella defensa Moran et al. (Enterobacteriaceae) persisted in all treatments. Ozone also affected aphid behaviour. The proportion of insects dispersing from diet cages was lower in the ozone treatments than in the control treatment. In addition, lipid peroxidation was higher at 150 p.p.b. than at 50 p.p.b. treatment, although not different from that in the control. The reduction in aphid dispersion coupled with increased mortality suggests that direct exposure to ozone could lower aphid efficiency as virus vectors. These results could be partially associated with mechanisms operating at individual scale (accumulation of oxidative damage). Overall, these experiments encourage reconsidering the impact of the direct effects of ozone on aphids when assessing the consequences of this component of global change on plant–aphid interactions.

“…Relay intercropping (Ma et al 2006) of agricultural co-systems as mutualistic plant protection, and use of transgenic cotton species were valuable in protection of the crop (Runzhi et al 2000). Ecological effects represented in O 3 (Menéndez et al 2010) on aphid infestation as well as use of remote sensing for detection of plant damage were investigated (Reising et al 2004). Chemical control, on the other hand, has gained great interest due to the widespread cultivation of cotton worldwide to satisfy the global requirements.…”

A series of quinoline derivatives have been elaborated from reaction of 2-(m-and p-acetylanilino)-quinolines 6a-b with aldehydes under Claisen-Schmidt conditions followed by cyclization with phenyl hydrazine and hydroxylamine. Reaction of 6a and 6b with hydrazine, semicarbazide and thiosemicarbazide, cyanoacetylhydrazide and some subsequent condensation reactions led to diverse quinoline derivatives. Anti-Aphid Aphis gossypii that harm cotton crop in Egypt was screened. Compound 12 showed an LC 50 value of 19429E-10 ppm which is much more active than Marshal (Carbosulfan), one of the broad spectrum insecticides widely used in this field.
