Heptyl butyrate
Based on 1 Customer Validation
Heptyl butyrate is a pheromone and is an attractant for many wasp species. Heptyl butyrate elicits hovering and landing behavior in Vespula germanica wasps. Heptyl butyrate enhances attraction when applied to protein baits, increasing Vespula germanica wasps’ likelihood of landing on baits.Heptyl butyrate can be used for the research of invasive Vespula germanica wasp population management.

Description
In Vivo
Heptyl butyrate (100 µL; volatile exposure; ambient field deployment) significantly enhances the attractiveness of protein baits to foraging V. germanica worker wasps, reducing time to first landing and increasing the number of landing wasps compared to untreated baits[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:V. germanica worker wasps[1]
-
Dosage:Pure heptyl butyrate (0.1 mL); 17.2 µg/mL; 0.172 µg/mL; 0.0172 µg/mL; 0.00172 µg/mL (each 0.1 mL in ethanol)
-
Administration:volatile exposure
-
Result:Elicited a mean of 31.5 hovering events and 6.5 landings per 10-minute experiment.
Attracted significantly fewer wasps in ethanol-diluted concentrations (17.2, 0.172, 0.0172, 0.00172 µg/mL) than pure form.
Showed no significant differences in wasp response among diluted concentrations.

Animal Model:V. germanica worker wasps[1]
-
Dosage:100 µL
-
Administration:volatile exposure
-
Result:Increased the number of landing wasps on treated baits compared to untreated baits in choice assay and no-choice assay.
Reduced mean time to first wasp landing to 34.33 s on treated baits, compared to 87.5 s on untreated baits.
Attracted no non-target insect species.

Solvent & Solubility
In Vitro:
DMSO : 100 mg/mL (536.77 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (13.42 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (13.42 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
