Abstract

:

In our article “Progressive Adaptation of a CpGV Isolate to Codling Moth Populations Resistant to CpGV-M.” (Viruses 2014, 6, 5135–5144; doi:10.3390/v6125135) [1] we obtained resistance values of the codling moth, Cydia pomonella, RGV laboratory colony [2], when challenged with Cydia pomonella Granulovirus, Mexican Isolate (CpGV-M), that were lower than those previously published [2]. Careful analysis of both the RGV colony and the CpGV-M virus stock used led to the realization that a low level contamination of this virus stock with CpGV-R5 occurred. We have made new tests with a verified stock, and the results are now in agreement with those previously published.

In our article “Progressive Adaptation of a CpGV Isolate to Codling Moth Populations Resistant to CpGV-M.” (Viruses 2014, 6, 5135–5144; doi:10.3390/v6125135) [1] we obtained resistance values of the RGV laboratory colony, when challenged with Cydia pomonella Granulovirus, Mexican Isolate (CpGV-M), that were lower than those previously published [2].

Careful analysis of both the RGV colony and the CpGV-M virus stock used led to the realization that a low level contamination of this virus stock with CpGV-R5 occurred.

We have made new tests with a verified stock, and the results are now in agreement with those published by Berling et al. [2] and in the same range as those obtained with another insect population, CpRR1 [3].

Below you will find the corrected Table 2 for our recently published article [1], in which line 7 has changed.

Table 2. Pathogenicities, measured by lethal concentration (LC)₅₀ and LC₉₀ of four viral isolates on Cydia pomonella laboratory colonies susceptible and resistant to CpGV-M.

^(a) The pathogenicity of CpGV-M on susceptible larvae is used as a reference level; ^(b) Results from [2]

As a consequence, the first paragraph in the Discussion section must also be changed:

“Codling moth resistant natural populations did not respond to control by CpGV-M. The resistance levels were variable, from a hundred-fold to more than a thousand-fold resistance as a function of the relative frequency of the resistant genotypes. The RGV resistant colony, developed from a natural population, exhibits a homogeneous resistance level against CpGV-M higher than 10⁵ (for LC₅₀) compared to the level for the susceptible colony.”

We apologize to the readers of Viruses for any inconvenience this may have caused.
