Dose-Dependent Insecticide Bioassay

Dose response curves were generated by using cumulative mortality in each concentration within the specific time period. Percentage of inhibition of emergence (IE%) was calculated using the following equation.
%IE=100-T/C100
where T is the number of emerged adults in tested units, C is the number of emerged adults in control unit5 ,26 , 39 (link).
Mortality and IE data obtained at each concentration was subjected to probit-regression analysis to determine LC50 and LC90 values and, IE50 and IE99 values using SPSS (v.9.0) program for Windows.
Residual effect in semi-field data was analyzed by one-way ANOVA. Kruskal–Wallis test was employed to compare adult emergence inhibition and adult emergence rates across all stand-alone and combination treatments. This non-parametric test was well-suited for comparing medians, particularly in cases where a non-normal distribution was observed, a condition not accommodated by the ANOVA test. A significance level of p < 0.05 was considered statistically significant.

Analyzing Muscle Composition in Food

Check if the same lab product or an alternative is used in the 5 most similar protocols
One-way analysis of variance (ANOVA) was used for BF and SM for physicochemical and volatile compound data. One-way ANOVA was followed by a post hoc Tukey honest significance (HSD) if a significant effect was found (p < 0.05). A Student t-test (p < 0.05) was performed to test for differences in physicochemical and volatile compound data between investigated muscles at the same processing stage. The general linear model (GLM) was used to estimate the effects of the factors (muscle (M); phase of production (P) and M × P) on the studied parameters (dependent variables). GLM test was performed for a significance level p < 0.05. All statistics were generated using the statistical program SPSS v.9.0 (SPSS inc., Chicago, IL, USA).

Statistical Analysis of Microbial Diversity

Check if the same lab product or an alternative is used in the 5 most similar protocols
Continuous and normally distributed variables are presented as arithmetic means and standard error of the mean (SEM). The significance of data differences (P≤0.05) was assessed using a nonparametric t-test in GraphPad Prism 7 (Graph Pad Software; La Jolla, CA, USA). The statistical analysis of beta diversity used the nonparametric “Adonis” method in the “vegan” package of the QIIME-incorporated version of the R software. Correlation analyses used Spearman’s rank correlation tests. Statistical analyses were performed in SPSS v.9.0 (SPSS Inc.; Chicago, IL, USA).

Statistical Analysis of Irrigation Effects

Check if the same lab product or an alternative is used in the 5 most similar protocols
All data were depicted using SigmaPlot v. 14.5 software (Inpixon, PA, USA) and analyzed by one-way ANOVA using SPSS v 9.1 (IBM, Armonk, NY, USA) to discriminate the effect of irrigation. Statistical comparisons were considered significant at p < 0.05, as indicated by the Pearson’s correlation coefficient. The degree of agreement of the regressions between variables was assessed by the coefficient of determination (R2) and the mean squared error (MSE).

Assessing Plant-Soil Water Dynamics

Check if the same lab product or an alternative is used in the 5 most similar protocols
Data were depicted using the SigmaPlot v. 14.5 software (Inpixon, PA, USA). Statistical comparisons were considered significant at p<0.05, using Pearson’s correlation coefficient. Relationships between indicators of plant and soil water status were explored by linear regression analyses. The coefficient of determination (R2) and mean squared error (MSE) were used to assess the goodness of fit. All analyses were performed with SPSS v. 9.1 (IBM, Armonk, NY, USA).

Irrigation Treatment Comparison Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
The data were analyzed by one-way ANOVA using SPSS v 9.1 (IBM, Armonk, NY, USA) to discriminate between irrigation treatments. Post hoc pair-wise comparison between all means was performed by a Least Significant Difference (LSD) test at p ≤ 0.05 (LSD0.05). The degree of agreement of the regressions among variables was evaluated through the coefficient of determination (r2) and the mean squared error (MSE).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
