“…First, citrus leafminer incidence was proportional to the amount of shoots susceptible to infestation, i.e., it depended signiÞcantly on the observed ßushing pattern. As in previous work (Jacas et al 1997), susceptibility to citrus leafminer infestation among rootstocks was similar despite differences in spring ßushing on ÔCleopatraÕ compared with the other rootstocks. However, it must be taken into account that, during this period, population levels of the citrus leafminer were probably reduced after the winter months (Lim and Hoy 2006) even though temperatures were high enough for development (Ujiye 1990).…”

“…Among these, selection of cultivars or generation of new varieties resistant to pests and diseases has been considered a major goal for pest control (Forner and Alcaide 1993, 1994, Jacas et al 1997, Duke and Lindgren 2006. It has been reported that some rootstock varieties may confer resistance against the attack of several different pests (Bowman et al 2001, Dadmal et al 2002, Verdejo-Lucas et al 2003.…”

We evaluated the influence of six different citrus rootstocks on the incidence of the citrus leafminer, Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae), and the aphid species, Aphis gossypii Glover and A. spiraecola Patch (Hemiptera: Aphididae), on 'Clementine de Nules' trees (Citrus clementina Hort. ex Tan.). Sampling was conducted during 2005 and 2006 in a grove of 3-yr-old trees in southern Spain with six rootstocks arranged in a completely randomized block design. Incidence (i.e., degree of infestation) and availability of resources for herbivores were assessed bi-weekly, and in addition, a "flushing index" was estimated as the number of young shoots (as a percentage of total shoots) susceptible to herbivore injury. Our results showed that contrasting factors affected the incidence of populations of P. citrella, A. gossypii, and A. spiraecola on 'Clementine de Nules'. Incidence of P. citrella was significantly dependent on the flushing pattern observed throughout the study, whereas the reverse was true for the aphid species. Among these, A. spiraecola had similar levels of incidence regardless of rootstock, whereas A. gossypii were found almost exclusively on leaves of 'Clementine de Nules' grafted on 'Cleopatra mandarin' (Citrus reshni Hort. ex Tan). Potential implications of these results on pest control are discussed.

“…The smallest (1.7 mm) pupae were observed on the C x R 4 hybrid, although not different from those obtained from the C x R 315 genotype (1.9 mm). Except for these two genotypes, the size of the pupae was in the range reported for several other citrus varieties (2.05-2.79 mm) (Jacas et al 1997). However the size of the pupae from all tangerine genotypes and 'Rugoso' lemon was much smaller than the size reported on oranges, lemon and pommel (2.59-2.77 mm) (Goane et al 2008).…”

The development and reproduction of the citrus leafminer (CLM), Phyllocnistis citrella Stainton, were evaluated in six citrus genotypes in order to identify genotypes with resistance traits that could be applied in a program for the development of citrus varieties resistant to the citrus leafminer. Tests were conducted under controlled laboratory conditions (25  1ºC, 70  10% RH, and 14h photophase). Seedlings of each genotype tested were infested with eggs obtained from a stock colony of CLM maintained on 'Cravo' lemon (Citrus limonia L. Osbeck), and the duration and survival of the eggs, larval and pupal stages, pupal size and weight, fecundity and longevity of adults, and sex ratio were evaluated. No in luence was observed on the duration and survival of eggs, larvae and pupae of P. citrella. However, pupae obtained in the hybrid C x R 4 were signi icantly smaller and lighter than pupae from the remaining treatments. Adult females from the hybrids C x R 4 and C x R 315 were the least fecund. However, the lowest value for the corrected reproductive potential (CRP) was recorded in the hybrid C x R 315 , suggesting that this genotype is the least favorable for the development and reproduction of CLM. On the other hand, the highest CRP value obtained in the 'Rugoso' lemon con irms the susceptibility of this genotype, indicating it as the most suitable for CLM.

“…The ßushing pattern during the year has a major inßuence on the severity of P. citrella damage, as in some citrus-producing areas the spring ßush is not affected by the P. citrella (Beattie and Smith 1993, Argov et al 1995, Binglin and Mingdu 1996, Jacas et al 1997. The seasonal ßushing pattern in citrus varies with geographic area, climate, physiological conditions, citrus species or variety, and year.…”

“…As a consequence, leaves become distorted and curled (Pandey and Pandey 1964). The P. citrella affects all citrus varieties grown (Pandey and Pandey 1964), and differences in susceptibility seem to be related to the ßushing patterns of the trees, i. e., yearly number of buds sprouting (Knapp et al 1995, Jacas et al 1997. Damage produced by P. citrella to a particular ßush of shoots is generally expressed as the percentage of leaf area lost due to mining, and there is a close relationship between this percentage and the number of mines per leaf (Huang and Li 1989, Knapp et al 1995, Schaffer et al 1997.…”

Seasonal population trends and damage to citrus trees by the leafminer Phyllocnistis citrella Stainton were studied in the Valencia area of eastern Spain from 1996 to 1999. The area-wide seasonal flushing pattern of citrus trees and leafminer population trends were determined in 10 mature citrus orchards. In the 10 orchards, the annual percentage of new shoots that developed in the spring ranged from 51 to 96% for individual orchards (mean of 80%). Phyllocnistis citrella populations damaged new leaves from July to November. During this period, approximately 45% of the new leaf area was lost due to leafminer mining. In addition, at three mature citrus orchards, two 'Navelina' sweet oranges from 1996 to 1999 and one 'Clementine' mandarin (variety 'Clemenules') in 1998 and 1999, the leaf area damage, spring flushing pattern, and crop yield were determined in trees sprayed one to three times a year with abamectin (Epimeck, 0.02%) to control P. citrella and compared with nonsprayed control trees. In these three orchards, damaged leaf area in summer-fall flushes was on average 52% in nonsprayed and 8% in sprayed trees. No significant differences were found between sprayed and nonsprayed trees in the spring flushing and flowering pattern, number of fruits or fruit diameter. In Mediterranean areas, P. citrella damaged only 5-15% of the annual new leaf area of mature trees and yield was usually not affected by the pest.
