Effect of three apple rootstocks on the population of the small red-belted clearwing borer, Synanthedon myopaeformis.

Ateyyat MA - J. Insect Sci. (2006)

Bottom Line: Abstract Experiments were conducted in Ash-Shoubak area of Jordan from June 2003 to September 2005 to study the effect of three apple rootstocks on the development of the small red-belted clearwing borer, Synanthedon myopaeformis (Borkh.) (Lepidoptera: Sesiidae), under field conditions.Mondial Gala apple trees grafted on the dwarfing rootstock M9 and the semi-dwarfing rootstock M26 were equally infested, whereas those grafted on MM106 showed significantly lower infestation levels.There was a significant effect of rootstock on the numbers of burrs present, and the percentage of burr knots infested by S. myopaeformis, with M106 having significantly fewer burrs, and a lower percent infested.

ABSTRACT
Abstract Experiments were conducted in Ash-Shoubak area of Jordan from June 2003 to September 2005 to study the effect of three apple rootstocks on the development of the small red-belted clearwing borer, Synanthedon myopaeformis (Borkh.) (Lepidoptera: Sesiidae), under field conditions. Mondial Gala apple trees grafted on the dwarfing rootstock M9 and the semi-dwarfing rootstock M26 were equally infested, whereas those grafted on MM106 showed significantly lower infestation levels. S. myopaeformis bore into burr knots that develop below a graft union on rootstocks and girdle the tree. There was a significant effect of rootstock on the numbers of burrs present, and the percentage of burr knots infested by S. myopaeformis, with M106 having significantly fewer burrs, and a lower percent infested.

f01: Monthly mean numbers of eggs of Synanthedon myopaeformis per tree (±SE) on Mondial Gala apple branches grafted on MM 106, M26 and M9 rootstocks in the Ash-Shoubak area from June 2003 to May 2005.

Mentions: No eggs were recorded from September to April during the study period (Figure 1). No significant differences in the number of eggs found in the three studied rootstocks were recorded in July 2003, June 2004 and May 2005 but significantly high numbers of eggs were recorded on M26 in August 2003 and April 2005 (Figure 1). M9 showed significantly higher numbers of larvae on June 2003, and M26 showed significantly higher numbers of larvae in August 2003, and from October 2004 to January 2005 (Table 3). No other significant differences were seen.
