The volatile organic compounds (VOCs) released from herbivore-infested plants can be used as chemical signals by parasitoids during host location. In this research, we investigated the VOC chemical signals for the parasitoid Aphytis melinus to discriminate between Aonidiella aurantii (California red scale)-infested fruit and non-infested fruit on three different citrus species. First, we identified the chemical stimuli emanating from non-infested and A. aurantii-infested citrus fruits via solid phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS) analyses and identified 34 volatile organic compounds (VOCs). The GC-MS analysis showed qualitative and quantitative differences between VOCs emitted from non-infested and infested citrus fruit. Two VOCs, d-limonene and β-ocimene, were significantly increased in all infested fruit, regardless of the fruit species. The response of the female adult A. melinus to olfactory cues associated with A. aurantii infested fruit was evaluated using a Y-tube olfactometer. In two-choice behavioural assays, A. melinus females preferred infested citrus cues over non-infested fruit. Females showed positive chemotaxis toward these VOCs in all tested combinations involving two dosages of synthetic compounds, d-limonene and β-ocimene, except for d-limonene at a dosage of 10 μL/mL. The application of these VOCs may help to enhance the effectiveness of bio-control programs and parasitoid mass-rearing techniques.

The purpose of this study was to define the population dynamics of the California red scale, Aonidiella aurantii Maskell (Heteroptera: Homoptera: Diaspididae), and its parasitoid, Aphytis melinus (Howard) (Hymenoptera: Aphelinidae), released to control the scale in grapefruit orchards in Turkey. Results revealed that A. aurantii exhibited 3 generations in the spring, summer, and autumn each year for 2004 and 2005. The highest population density of second-stage larvae occurred on leaves at densities of 18 and 46 individuals per 4 cm2 with the lowest density occurring on stems at levels of 7 and 8 individuals per cm2 in grapefruit in both years. Parasitoid populations increased in the summer and into autumn. Parasitation rate was increased by releasing A. melinus adults in the orchards. In 2004 and 2005, respectively, the highest parasitization rate occurred on infested leaves with 60.8% and 40.8%, followed by infested fruits at 25% and 54.5%, on infested shoots with 36.4% and 19.3%, and on infested stems with 8.33% and 15.4%. Second-stage and unmated females of red scale were most dense during the spring, summer and autumn each year, thus, appearing to be the best time for release of parasitoids. These results suggest that in releasing A. melinus in grapefruit orchards in Turkey, 50% of the parasitoids should be released in early spring, 25% in summer, and 25% in autumn.

The size of California red scale Aonidiella aurantii (Maskell, 1879) (Homoptera: Diaspididae) is the most reliable indicator in terms of host quality for Aphytis melinus (DeBach, 1959) (Hymenoptera: Aphelinidae) as well as for the efficiency of its biological control. Our study consisted in comparing the cover and body size of each scale developmental stage belonging to two different populations: one from Algeria and the other one from Turkey. The two scale populations were taken from lemon trees during 3 months. We compared measurements between the two localities and also between the plant organs. The larger individuals were those from Algeria. The same results were confirmed through the plant substrate on which scale was fixed: this size variation observed is mainly explained by climatic variations between the two countries and its repercussions on phenology and metabolism of the host plant. In addition, a higher parasitism rate was noticed in the Algerian scale population compared to that of Turkey.

AbstractThree populations of Aonidiella aurantii (Maskell) were studied on orange trees at two sites in the hot Transvaal lowveld in South Africa. The first two were on the same trees, which had severe scale in the tree crowns and a low infestation in the bottoms. The third population, at a second site, was high and relatively evenly-spread over the whole tree. In previous years, the parasitoids Aphytis africanus Quednau and A. melinus DeBach had been unable on their own to reduce the high scale populations. Once a certain scale density level on the tree framework had been breached, a proportionately large number of susceptible scales escaped parasitism and reached the gravid female stage, which is invulnerable to attack. The ineffectiveness of parasitoids in these circumstances, resulting partly from their narrow niche breadth, was compounded by peak numbers only being reached late in the season. By this time, the large number of adult scales had already rendered the fruit unmarketable. In both sites, the predator Chilocorus nigritus (F.) was introduced and the trees also received commercial applications of petroleum oil. In one site, this oil treatment was restricted to the tree crowns. Although overall parasitism of vulnerable stages was relatively unaffected by these abiotic and biotic controlling factors, there was a shift to increased percentage parasitism of the virgin female away from the other susceptible stages. In addition, it was confirmed that the broad attack niche provided by C. nigritus, which preys on all developmental stages of the scale, readily complements parasitoid activity and can be of major economic importance.

California red scale (CRS), Aonidiella aurantii (Maskell) (Hemiptera: Diaspididae), one of the most important pests of citrus worldwide, began to cause damages in eastern Spain in 1986. The main biological control agents of A. aurantii in this zone are the native parasitoid A. chrysomphali (Mercet) and the introduced A. melinus DeBach (both Hymenoptera: Aphelinidae). Nevertheless, the control they exert is insufficient. In order to improve the biological control of A. aurantii we studied several biotic factors that may affect the efficiency of A. chrysomphali and A. melinus in the field. More concretely, we studied the spatial and temporal variation in the scale size, the host sizes used by A. chrysomphali and A. melinus as well as the influence of host size on various parasitoid traits. Moreover, we studied the foraging ecology and the effect of the ants native to the Mediterranean on the populations of the scale and, finally, the nutritional state and food sources used by adult A. melinus in the field. In the field, the body size of A. aurantii varied with plant substrate, locality, time of the year, and probably, with the nutritional state of the host plant. Plant substrate was found to substantially influence the body size of A. aurantii with scales being significantly larger on fruits that on leaves or twigs. Another important source of variation for A. aurantii size was geographic location since significant differences were found among orchards. Moreover, significant seasonal variation in the body size of A. aurantii was observed; body sizes were smaller during summer and autumn, apparently due to the effect of temperature. Finally, a positive relationship between the content of potassium in leaves and scale size was observed. From all the above factors, temperature related seasonal variation had the most profound effect on A. aurantii size. Aphytis chrysomphali and A. melinus used different sizes of A. aurantii in the field.

The California red scale Aonidiella aurantii is considered a key citrus pest. Parasitoids of genus Aphytis are the most important natural enemies of A. aurantii. In the Mediterranean basin, the native A. chrysomphali and the introduced A. melinus are the most abundant parasitoids of A. aurantii. The introduced has completely displaced the native A. chrysomphali in the south, whereas they coexist in the north-east of the Iberian Peninsula. We have used this well-known host-parasitoid system to investigate some gaps on the behavioural ecology of hymenopteran parasitoids, which have been exposed in the introduction. This knowledge will contribute to improve their use in biological control programs, especially in the case of A. aurantii in the Mediterranean basin.
El piojo rojo de California, Aonidiella aurantii, se considera una de las plagas de los cítricos más importante a nivel mundial. Los principales enemigos naturales de A. aurantii son los parasitoides del género Aphytis, siendo los más abundantes en la cuenca mediterránea el nativo Aphytis chrysomphali y el introducido A. melinus. En las zonas del sur de la Península Ibérica, A. melinus ha desplazado completamente al nativo A. chrysomphali, mientras que en el noreste ambos parasitoides coexisten. Durante el desarrollo de esta tesis, hemos utilizado este conocido sistema de parasitoides-hospedante para investigar algunos aspectos poco conocidos en la ecología del comportamiento de los parasitoides himenópteros, los cuáles han sido mencionados en la introducción de la tesis. Este conocimiento contribuirá a mejorar su uso en programas de control biológico, especialmente en el caso de A. aurantii en la cuenca mediterránea.
