Table 2.
Concentrations used in tests aimed at evaluating the toxicity of combinations vs individual Bacillus thuringiensis (Bt) formulations, against the pine weevil, Hylobius abietis
| Treatment (abbreviation) | Concentration (g or mL L−1; vol:vol) |
|---|---|
| Bt galleriae (BeetleGONE; B) | 200 g L−1 |
| Bt israelensis (VectoBac; V) | 400 g L−1 |
| Bt tenebrionis (Novodor; N) | 800 mL L−1 |
| Bt galleriae + Bt israelensis (BV) | (1:1) |
| Bt galleriae + Bt tenebrionis (BN) | (1:1) |
| Bt israelensis + Bt tenebrionis (VN) | (1:1) |
| Bt galleriae + Bt israelensis + Bt tenebrionis (BVN) | (1:1:1) |
Treatments represent the individual formulations tested in the control group (high concentration of each strain; grams or milliliters of product per liter of water, g or mL L−1) and all possible formulation combinations (volume ratio when mixing formulations, vol:vol).
