Correction: Wang, C.; et al. Changes in Indoor Insecticide Residue Levels after Adopting an Integrated Pest Management Program to Control German Cockroach Infestations in an Apartment Building. Insects 2019, 10, 304

Following the publication of our article [1], we found that an incorrect data set was used in the regression analysis. Figure 1 and the associated analysis results need to be changed.

The corrected Figure 1 and Figure 1 legend are listed below:

Figure 1.

Association between insecticide residue concentration per apartment (mean residue concentration measured in bedroom and kitchen) and initial cockroach count. For regression analysis, those apartments without detected residue and those with a cockroach count <10 were excluded because there are many apartments with small counts, which cause the data to be not normal even after logarithmic transformation.

On page 5 (line 2–4), the sentence is changed to the following: “Insecticide residue concentration in apartments was not correlated with the cockroach counts recorded by the cockroach traps (F = 0.38; df = 1, 25; p = 0.54, R² = 0.02) (Figure 1)”.

On page 9, line 2, within Section 5, “Conclusions”, the following phrase is deleted: “with concentrations closely correlated with the cockroach infestation”.

The authors wish to apologize for the mistake made and inconveniences caused.
