The parasitoids ofAonidiella aurantii (Maskell),Lepidosaphes beckii (Newman) andParlatoria pergandii Comstock were studied in a Navel orange grove in Valencia, Spain during three years. Four species ofAphytis were identified on yellow sticky traps,Aphytis chrysomphali (Mercet),Aphytis melinus Debach,Aphytis lepidosaphes Compere andAphytis hispanicus (Mercet). No consistent annual pattern was observed in the flight of adults.A. melinus, introduced some years earlier in the grove, was found in… 
Displacement of Aphytis chrysomphali by Aphytis melinus, parasitoids of the California red scale, in the Iberian Peninsula
Overall, higher levels of parasitism were recorded in fruit than in twigs, and the recent displacement of A. chrysomphali by A. melinus is revealed, which will be useful in the decision of IPM strategies for this pest.
Evaluation of the Effectiveness of Spirotetramat on the Diaspine Scale Parlatoria pergandii in Citrus Orchards
All the tested concentrations of this product were effective on the population of P. pergandii and this product showed a less negative impact on the parasitized females with the low concentration compared to the high concentrations, especially for the female stages F2 and F3.
Parasitoid competitive displacement and coexistence in citrus agroecosystems: linking species distribution with climate.
Previous literature on the behavior of Aphytis species in the laboratory under different temperature and humidity conditions are combined with field results to confirm the role of spatiotemporal weather conditions and seasonal changes in host stages on the variation of Apytis relative abundance and parasitoid coexistence.
Mating disruption of California red scale, Aonidiella aurantii Maskell (Homoptera: Diaspididae), using biodegradable mesoporous pheromone dispensers.
Mating disruption has been found to be an efficient technique to control this pest, working equally well to a correctly sprayed oil treatment and the effects of the pheromone on natural enemies.
Deployment of mating disruption dispensers before and after first seasonal male flights for the control of Aonidiella aurantii in citrus
The late application of MD dispensers before the second CRS male flight has proven to be effective, suggesting a new advantageous way to apply mating disruption, as demonstrated in two locations with different pest pressure.
Mortalidad natural del piojo rojo de California, Aonidiella aurantii, en cítricos de la Comunidad Valenciana y sus parasitoides asociados
espanolAonidiella aurantii es una de las principales plagas de los citricos en Espana. En este trabajo se han estudiado diferentes factores de mortalidad natural como son: el parasitismo, las
Niveles de parasitismo y especies de parasitoides del piojo rojo de California Aonidiella aura ntii (Hemiptera: Diaspididae) en cítricos de la Comunidad Valenciana
Natural enemies of the citrus red scale (CRS) Aonidiella aurantii (Maskell) and parasitoids captured on yellow and pheromone traps in 100 citrus orchards of the Citrus Phytosanitary Survey of Valencia Gobernment are sampled.


Parasitism by Aphytis chrysomphali, Mercet and A. melinus Debach of Californian red scale, Aonidiella aurantoo (Maskell), in relation to seasonal availability of suitable stages of the scale
Improved approach to red scale control is proffered, namely that attempts be made to augment the effectiveness of the established Aphytis by devising methods for increasing the proportion of available stages in red scale populations during late spring and early summer.
The Hymenopterous Parasites of Citrus Armored Scales in Israel (Hymenoptera: Chalcidoidea)
In an extensive survey covering the main citrus-growing regions of Israel, 17 forms of chalcidoid parasites were obtained, including 11 forms of Aphytis, and special attention was given to parasitism trends in California red scale populations.
Spatial and temporal population patterns of Aonidiella aurantii (Maskell) (Hemiptera: Diaspididae) parasitoids (Hymenoptera: Aphelinidae and Encyrtidae) caught on yellow sticky traps in citrus
Aphytis was by far the most economically important of the parasitoids, and pest management practices should aim at conserving the pool of Aphytis within the orchard as far as practicable.
Population fluctuations on parasites ofLepidosaphes beckii Newm. andCeroplastes floridensis Comst.
Six species of hymenopterous primary parasites together with one secondary parasite were found on L. beckii, and lepidosaphes was the most common parasite on C. floridensis.
Growth, Development and Innate Capacity for Increase in Aphytis Chrysomphali Mercet and A. Melinus Debach, Parasites of California Red Scale, Aonidiella Aurantii (Mask.), In Relation to Temperature.
A, melinus produced more female progeny and more than twice as many total progeny as A. chrysomphali; it also destroyed almost twice asMany hosts through oviposition and mutiliation; it is possible that Aphytis spp.
Studies in Ovipositional Behaviour and Control of Sex in Aphytis Melinus Debach, a Parasite of California Red Scale, Aonidiella Aurantii (Mask.).
The growing adult female red scale was the most preferred stage for A. melinus, followed by the second growing instar and lastly the male prepupa, and the mean size of parasites produced within the third instar decreased as the number of parasites per host increased.
Biological Control by the Parasitoid Aphytis melinus, and Population Stability of the California Red Scale
Strong evidence exists for a refuge from parasitism, which may account for the apparent stability of the scale-Aphytis system, which is under successful biological control by its parasitoid Aphytis melinus.

Flight Response of Aphytis melinus (Hymenoptera: Aphelinidae) and Scirtothrips citri (Thysanoptera: Thripidae) to Trap Color, Size, and Shape
Aphytis melinus DeBach responded significantly more to green and yellow traps than to white, blue, fluorescent yellow, clear, black, or red; Scirtothrlps citri (Moulton) responded significantly more
