Ectemnius scaber is a species of square-headed wasp in the family Crabronidae. It is found in North America. [1] [2] [3] [4]
These two subspecies belong to the species Ectemnius scaber:
Apple scab is a common disease of plants in the rose family (Rosaceae) that is caused by the ascomycete fungus Venturia inaequalis. While this disease affects several plant genera, including Sorbus, Cotoneaster, and Pyrus, it is most commonly associated with the infection of Malus trees, including species of flowering crabapple, as well as cultivated apple. The first symptoms of this disease are found in the foliage, blossoms, and developing fruits of affected trees, which develop dark, irregularly-shaped lesions upon infection. Although apple scab rarely kills its host, infection typically leads to fruit deformation and premature leaf and fruit drop, which enhance the susceptibility of the host plant to abiotic stress and secondary infection. The reduction of fruit quality and yield may result in crop losses of up to 70%, posing a significant threat to the profitability of apple producers. To reduce scab-related yield losses, growers often combine preventive practices, including sanitation and resistance breeding, with reactive measures, such as targeted fungicide or biocontrol treatments, to prevent the incidence and spread of apple scab in their crops.
Porcellio scaber, is a species of woodlouse native to Europe but with a cosmopolitan distribution. They are often found in large numbers in most regions, with many species preying on them.
Crabronini is a tribe of square-headed wasps in the family Crabronidae. There are more than 40 genera and 1,500 described species in Crabronini. Wasps of this tribe are mostly small to very small wasps. Typical of this tribe are the forewings with a single submarginal cell, the lack of membranous metanotal and propodeal modifications, and a square-shaped head.
The PRI disease resistant apple breeding program is a joint project of the Purdue University, Rutgers University, and the University of Illinois, to breed apple cultivars to be resistant to apple scab. PRI stands for 'P'urdue, 'R'utgers and 'I'llinois.
