... The applied pesticides leave residues on the fruits, which is a problem especially in exported products (Eşkin et al., 2016). On the other hand, studies on the morphology of P. citrella are relatively limited (Rathod et al., 2020, Kernasa et al., 2008, Abo et al.,2006, Jacas and Garrido,1996. It was detected in principal studies regarding integrated strife in Turkey's citrus gardens that citrus pests have quite a high amount of natural enemies (Kansu and Uygun, 1980;Uygun, 2001). ...
Contribution to the morphology, biology and distribution of Citrus leaf miner Phyllocnistis citrella Stainton (Lepidoptera: Gracillaridae) and their parasitoid (Turkey). Misc. Pap. 220: 1-6, 12 figs. Effective and permanent success against to pests in biological control can only be achieved by identifying the pests, knowing the type of damage on the plants and revealing their natural enemies. In this study, the species in the citrus garden and their parasitoids were examined: Phyllocnistis citrella Stainton (Lepidoptera: Gracillaridae), Planococcus citri (Risso) and Aphis spiraecola (Patch) (Hemiptera), Citrostichus phyllocnistoides (Narayanan), Cirrospilus ingenuus (Gahan) (Hymenoptera: Eulophidae). Larvae, pupae and adults of P. citrella were described. The natural enemies that is effective for controlling P. citrella were identified and introduced. Relationship between the detected insects was evaluated.
This study aimed to highlight the Citrus clementina nutritional quality leaves significance on infestations distribution of the citrus leaf-miner Phyllocnistis citrella Stainton (Lepidoptera; Gracillariidae). For each plant phenological cycle, infestation rates of P. citrella , carbon, nitrogen and phenolic compounds (CPT) were determined from collected leaves. The findings of P. citrella infestations show saved spring shoots, severely attacked autumn and summer leaves, and progressive infestations on additional leaves. Also, results revealed lower content of carbon in spring leaves as compared to additional, summer and autumn ones. In contrary, nitrogen was found to be higher in spring leaves. Summer and spring leaves contain, relatively, significant levels of total phenolic compounds. C/N balances seem to be substantial in summer, followed by additional and then spring and autumn leaves. Separately, infestations are negatively correlated with C and N accumulations, and positively with CPT and C/N. These ingredients are the main components of plant sap used by phytophagous sucking bugs. Herein, P. citrella infestation depends on the balance between nutritional (C and N) and deterrent (CPT) components. Effectively, as compared to the first cycle, P. citrella activates when the sap has nutrient-rich levels (especially carbon) and suitable C/N balance, despite the high level of diluted phenolic compounds in the mixture (SmS and AuS). This is clearly observed on additional shoots; less deterrents and abundance of nutritional nutrients. Remove additional shoots, as soon as they appear, can be a promising strategy of control, and obviously reduce P. citrella adults spread on summer shoots.
