“…Different species of peppermint can show the different insecticidal efficacy of the EOs extracted from them. EO from Mentha longifolia was found to be effective against adult L. decemlineata with an LC 50 of 3561 ppm [71], which is very close to the value recorded in the present study for L2 larvae after 48 h (0.3449%), while EO from Mentha spicata in the same authors' study was not effective against the pest.…”

Peppermint essential oil (EO) has been extensively tested to date in reducing stored-product insects and insects of public health concern with very promising results, while only a few studies target important crop pests. There is also very little information on the effects of peppermint EO on non-target organisms, especially concerning contact and gastric effects at the same time. The goal of the investigation was the determination of the effect of peppermint EO on the mortality of Aphis fabae Scop.; the feeding intensity and weight gain of Leptinotarsa decemlineata Say. larvae; and the mortality and voracity of non-target organism Harmonia axyridis Pallas larvae. Our research indicates promising use for the M. piperita EO against aphids and young larvae (second instars) of the Colorado potato beetle. M. piperita EO showed good insecticidal efficacy against A. fabae with LC50 = 0.5442% for nymphs and 0.3768% for wingless females after 6 h. Over time, the LC50 value decreased. For the second instar larvae of L. decemlineata, the LC50 values were 0.6278%, 0.3449%, and 0.2020% after 1, 2, and 3 days of the experiment, respectively. On the other hand, older larvae (fourth instar) were characterized by significant resistance to the tested oil concentrations with LC50 value = 0.7289% after 96 h. M. piperita oil (contact and gastric effects) at a concentration of 0.5% was found to be toxic to young larvae (2 and 5 days old) of H. axyridis, while EO at a concentration of 1% was toxic to 8-day-old larvae. Thus, for the sake of ladybug safety, it would be advisable to use EO from M. piperita against aphids at concentrations lower than 0.5%.

“…There is no available information on the effect of EO from T. occidentalis, as well as from other plants of the Cupressaceae family, on L. decemlineata. Results using other EOs indicate that CPB is significantly resistant to EOs [50,59] and that adult forms of CPB are more resistant than larval forms [60]. M. piperita EO caused mortality in L2 CPB larvae with LC 50 values of 0.3449% and 0.2020% after 2 and 3 days of the experiment, respectively, while for older larvae (L4) the LC 50 value was 0.7289% after 96 h [50].…”

“…There was also wide variation in the effectiveness of EO against adult CPB from different plant species, even from the same family. EO extracted from Mentha longifolia used against adult CPB showed effectiveness with LC 50 = 3561 ppm (after 24 h), while EO from Mentha spicata was ineffective [59]. For EO from lavender (acetone as solvent), the same authors calculated LC 50 = 4154 ppm.…”

“…EOs with acetone as a solvent extracted from Origanum vulgare Mill. and Satureja hortensis L. caused only 20% mortality of adult CPB after 24 h at concentrations of 8000 and 7000 ppm, respectively [59]. There was also wide variation in the effectiveness of EO against adult CPB from different plant species, even from the same family.…”

Thuja occidentalis L. essential oil (EOTO) and its compounds, such as terpinyl acetate, bornyl acetate, and β-thujone, are claimed to be highly effective against some storage pests, sanitary insects, or pests of fruit trees, while data about its use in protecting field crops are very scarce. There is also a lack of information in the literature about the insecticidal value of water extracts from T. occidentalis (WETOs). Both essential oils (EOs) and water extracts (WEs) from various plants have advantages and disadvantages in terms of their use as insecticides. EOs are generally more effective, but their preparation is more complicated and quite expensive. In turn, WEs are simple to prepare and cheap, but they often have limited effectiveness. Moreover, significant differences in responses exist depending on the species of the donor plant, the method of preparing the extract, its concentration, the species of the pest being controlled, the developmental stage, and even the gender of the pest. The goals of the research were to assess the effect of EOTO and WETOs prepared from dry and fresh matter on the mortality, feeding, and body mass changes of important crop pests, i.e., the black bean aphid, pea leaf weevil, and Colorado potato beetle (CPB), respectively, as well as on the mortality and voracity of non-target organism Asian lady beetle young larvae. EOTO showed significant aphicidal activity with LC50 = 0.8267% and 0.2453% after 42 h of the experiment for nymphs and wingless females of black bean aphid, respectively. Adults of CPB were more resistant to EOTO than aphids, with LC50 values for females equal to 1.5327% and 1.3113% after 48 h and after 72 h of the experiment. There was no significant effect of EOTO on CPB foraging. Calculated LC50 values for pea leaf weevil adults were lower than those for CPB (0.9638% and 0.8573% for males after 12 h and 24 h, respectively). In the case of this pest, a clear reduction in foraging was obtained, with higher concentrations of EOTO resulting in more pronounced reductions in foraging behavior. Concentrations of EOTO above 0.5%, which showed efficacy against the aphid, were lethal to 3-day-old larvae of the Asian lady beetle. WETOs, in turn, showed significant potential in inhibiting adult pea leaf weevil feeding, with very low or no effectiveness in reducing A. fabae and CPB, respectively.
