Research was conducted to determine whether Phyllocnistis citrella Stainton (Lepidoptera, Gracillariidae) has any preference in attacking either the upper or the lower surface of the leaves of citrus trees. This investigation took place during the year 1999 at Marathon (Attica, Central Greece) while studying the dispersal of P. citrella on the leaves of three different types of citrus trees. Data on the overwintering and parasitism of P. citrella from different areas in Greece are also presented during the years 1999-2002. In addition, the effect of P. citrella infestation on imidacloprid-treated and untreated tangerine trees was comparatively studied. The parasitoids collected were Pnigalio sp. (Hymenoptera, Eulophidae), Cirrospilus sp. (Hymenoptera, Eulophidae), Neochrysocharis formosa (Westwood) (Hymenoptera, Eulophidae) and Citrostichus phyllocnistoides (Narayanan) (Hym., Eulophidae).

Laboratory Conditions

The citrus leaf miner, <em>Phyllocnistis citrella</em> Stainton (Lep., Gracillariidae), is one of the most destructive pest of citrus and related Rutaceae and ornamental plants in Iran. Larvae damage leaves by creating serpentine feeding mines, which have been lead to reduce yield. Resistance and toxicity problems derived from synthetic insecticides have made it necessary to find more effective and healthier alternatives; therefore, bio-insecticides (<em>i.e</em>., <em>Bacillus thuringiensis</em>) are becoming an important component in plant protection. The aim of the present study was to evaluate the efficiency of <em>B. thuringiensis</em> against <em>P. citrella</em>. Eight <em>B. thuringiensis</em> concentrations were used against <em>P. citrella</em> L3 on orange and mortality was recorded at 1, 4, 7 and 10 days after spraying. The results showed that <em>B. thuringiensis</em> significantly affected mortality of <em>P. citrella</em>. After 1, 4, 7 and 10 days of spraying 108 concentration of <em>B. thuringiensis</em> had significantly caused the highest mortality to the pest with 59.8, 68.4, 73.6 and 77.0%, respectively. Then the mortality percent decreased until it reached 6.5, 9.5, 39.3 and 46.7% at 101 concentration, respectively. In conclusion, the study indicated that <em>B. thuringiensis</em> is effective in controlling <em>P. citrella</em> under laboratory conditions.

And Control

Citrus leaf miner, Phyllocnistis citrellaStainton,1856 (Lepidoptera,Gracillariidae), is one of the main pests of the culture of acid lime Tahiti and control chemical is the primary method of control. The objective of this study was to testthe effect of insecticide treatments associated with adjuvant, in increasing the efficiency of control of citrus leaf miner in acid lime Tahiti. An experiment was installed in statistical design of randomized blocks with five treatments and four repetitions. The treatments consisted of a control treatment without application of pesticides and the use of the insecticide Ampligo® (clorantraniliprole + lambda-cialotrina) at the recommended dosage, at half the recommended dose and associated with the adjuvant. Three applications were carried out respecting the shortage period of the product. The damages of citrus leaf miner wereassessed in five branches of the central plant.Fruits wereharvest and determining the number and the mass (kg) of fruit per plant.The data were subjected to analysis of variance (F test) and the means were compared by Tukey test (P ≤ 0.05). Also the data were submitted to multivariate analysis using hierarchical cluster analysis techniques and principal component analysis (PCA). All treatments were effective in reducing the attack symptoms of citrus leaf miner, highlighting insecticide in half dosage and application of insecticide in half dosage with the adjuvant.The multivariate analysis was effective in discriminating application treatments of insecticides and adjuvant, and showa direct relationship between the citrus leaf miner and the decrease in fruit production.
