“…For example, of the 365 genotypes represented by Pyrus and cultivars, only 20.5% did not show fire blight under natural infection conditions (Sestras et al, 2008). In another study, among 160 European pear genotypes, only 8.1% were found to be highly tolerant or resistant to C. pyri attacks under natural infestation conditions (Nin et al, 2015). In the last study, 46.3% of the cultivars were qualified as susceptible.…”

“…In new orchards, improved monitoring techniques and novel integrated pest management (IPM) techniques that protect the contribution of beneficial insects to the natural control of pear psylla are required (Horton, 1999;Civolani, 2012). Additionally, the introduction of psylla-resistant cultivars would drastically cut production costs (Bell, 1992;Nin et al, 2015). Consequently, the production of psyllaresistant cultivars remains a significant objective for pear breeders.…”

“…C. pyri has 4-5 generations per year in Europe (Civolani, 2012), and the cultivar, rootstock, ecological circumstances, and management practises of the orchard, among other factors, can have a significant impact on how the assault manifests (Sestras et al, 2008(Sestras et al, , 2020Nin et al, 2012Nin et al, , 2015Shaltiel-Harpaz et al, 2018). However, thorough knowledge of a pest's life cycle is essential for improving pest control and management (Civolani, 2012).…”

The species of pear sucker, also called pear psylla or pear psyllid, which are destructive insects belonging to the genus Cacopsylla (Hemiptera: Psyllidae) cause substantial damage to pear tree plantations. Two consecutive years of research were conducted on the population structure and biological cycle of psylla in a small, elderly, and unmaintained pear orchard in northern Romania. Of the two identified species (C. pyri L. and C. pyricola Forster), C. pyri dominated the psylla population with a percentage of 77.8-80.1%. Adults of both species emerge from hibernation in the first part of March and produce three generations per year. First-generation adults emerge in the first decade of June, the second generation in the last decade of July, and the third generation in the first decade of September as they enter the hibernation phase. Larvae of the first generation appear in the second half of April, the second generation at the end of June - the beginning of July, and the third generation in the second decade of August. There have been reports of up to 11 adults and 27 larvae per leaf, 9 larvae per petiole, and 14 larvae per fruit. The number of adults captured on yellow sticky traps exposed on the southern side of the tree crown was significantly higher compared to the northern side. Following the intense attack, the well-known cv. ‘Williams’ was heavily affected, pear trees were badly defoliated, blackened, and aged prematurely. The climatic conditions of the two years did not influence the phenology of the pests, but the importance of monitoring psyllids is widely argued, considering that it remains the key to integrated protection programs in pear orchards.

“…'Comice' is one of the main pear varieties in many countries and was reported as a susceptible host plant to pear psyllid (Bellini and Nin, 2002;Fischer, 2009). Nin et al (2015) reported that 'Comice' suffered medium injuries to psylla attack and classified into medium susceptible class. Cross breeding between 'NY10353' as male parent and 'Comice' as female parent has shown a great degree of psylla resistance in controlled conditions (Musacchi et al, 2005;Pasqualini et al, 2006).…”

The pear psylla, Cacopsylla pyricola (Foerster, 1848) (Hemiptera: Psyllidae), is one of the most detrimental pests in commercial pear orchards. Varieties with low infestation level to pear psylla would offer to integrated psyllid management. The natural infestation level of six pear varieties to pear psylla was studied under field conditions during three successive years. The pear varieties consisted of ‘Comice’, ‘Buerre Giffard’, ‘Bonne Louise’, ‘Felestini’, ‘Shahmiveh’, and ‘Sebri’. Psyllid population was sampled weekly by limb jarring method and selecting 10 leaves randomly per tree. The results indicated that the size of the psyllid population on the tested pear varieties was significantly different (F 5, 30 = 816.18, p < 0.0001). ‘Shahmiveh’ and ‘Sebri’ showed high and low susceptible, respectively, to pear psylla infestation. The natural infestation level of C. pyricola was 37.01 % and 35.8 % lower on ‘Bonne Louise’ and ‘Sebri’, respectively, than on ‘Shahmiveh’. These varieties may be used for crossing in breeding programs to develop plant resistance to C. pyricola and may be exploited in integrated psyllid management.

“…The earliest efforts to breed psyllid resistance into commercial pear cultivars began in the 1920s at government laboratories in North America where hybrids of Asian and European species were evaluated for resistance to C. pyricola (Nin et al 2012). East Asian pear species are resistant to the European pear psyllids, but small fruit size and gritty or coarse texture of the fruit limits their use in breeding programs.…”

The pear psyllids (Cacopsylla Ossiannilsson; Hemiptera: Psylloidea: Psyllidae) are a taxonomically difficult group of at least 24 species native to the Palaearctic region. One or more species occur in most pear-growing regions, in some cases as invasive introductions. Existing reviews of this group are primarily of taxonomic focus with limited overviews of biology. The earliest biological studies of the pear psyllids centered on a core group of a few western European species. In part, this focus arose because diversity of the pear psyllids was poorly understood. As taxonomic understanding has advanced over the last 3 decades, research has expanded taxonomically. Increasing difficulties in controlling the pear psyllids additionally has contributed to growth in research. Here, we review a now-extensive literature on diversity, biology, and management of the pear psyllids. Three broad observations emerged from this synthesis. First, large gaps in biological understanding of the pear psyllids persist for several geographic faunas, most notably for psyllids of the Eastern Palaearctic region. Second, taxonomic diversity is accompanied by biological diversity. Despite the commonality in host use among the pear psyllids, with each species being limited to development on Pyrus, striking differences exist among species in life cycles, wintering, and other biological traits. Third, many of the tools being used to manage pear psyllids today are in existence because of the long history of basic research which has targeted these pests. These tools include new insecticides of higher selectivity, various cultural and horticultural tactics, and practices that conserve natural enemies in orchards.
