β-cyclodextrin (β-CD) is a good host for the encapsulation of fennel and basil essential oils
(FEO and BEO, respectively) and the formation of inclusion complexes (ICs) using the co-precipitation
method. According to the results of the GC/MS analysis conducted in this study, monoterpenes and
monoterpenoids were the dominant chemical groups in total FEO, while in BEO, these two groups
occurred along with sesquiterpenes and sesquiterpenoids. The presence of dominant compounds
from both EOs was validated using the FT-IR spectra of ICs, which indicated successful complexation.
Analyses conducted using SPME/GC-MS showed the continuous emission of volatiles over 24 h from
both ICs. Under SEM, particles of both ICs appeared to have a rectangular or rhomboid morphology
and few aggregates. The insecticidal properties of EOs and ICs with β-CD were tested on the
Colorado potato beetle (CPB) as a model pest. The inclusion complex of β-CD with FEO altered the
developmental dynamic and body mass of the CPB. The initial increase in the proteolytic activity of
CPB larvae fed with potato plants sprayed with ICs was not maintained for long, and the proteolytic
efficacy of treated larvae remained in line with that of the control larvae. Future investigations will
focus on manipulating the volume of EOs used and the treatment duration for optimal efficacy and
potential application.
