Biological Control Against the Cowpea Weevil (Callosobruchus Chinensis L., Coleoptera: Bruchidae) Using Essential Oils of Some Medicinal Plants

Abstract Chickpea (Cicer arietinum L.) is a valuable foodstuff but unfortunately this legume is prone to insect attacks from the chick pea weevil (Callosobruchus chinensis L.). This serious pest damages the chickpea and causes decreases in the yield and in the nutritional quality. Biological control is being used to deal with this problem. We tried different doses of the essential oils of three new medicinal plants, namely Salvia verbenaca L., Scilla maritima L., and Artemisia herba-alba Asso to limit the damage of the chick pea weevil pest, and to protect consumer’s health. To determine the effect and efficiency of the oil, the tests were conducted using the different biological parameters of fertility, longevity, and fecundity, under controlled temperature and relative humidity (28°C and 75%). The effectiveness of organic oils was demonstrated. We tested these oils on the germination of seeds. The obtained results showed that the tested plant oils have a real organic insecticide effect. The essential oil of Artemisia proved most effective as a biocide; achieving a mortality rate of 100%. A significant reduction in longevity was observed under the effect of 30 μl of S. maritima (1.3 days) and S. verbenaca (2.8, 4.6 days), respectively, for males and females compared to 8 and 15 days for the control. For fecundity, an inhibition of oviposition was obtained using 30 μl of Salvia and Scilla essential oils. The test on the seed germination using different essential oils, showed no damage to the germinating seeds. The germination rate was 99%. These findings suggest that the tested plants can be used as a bioinsecticide for control of the C. chinensis pest of stored products.

Background: The use of essential oils is receiving increasing attention worldwide, as these oils are good sources of several bioactive compounds. Nowadays essential oils are preferred over synthetic preservatives thanks to their antioxidant and antimicrobial properties. Several studies highlight the beneficial effect of essential oils extracted from medicinal plants to cure human diseases such as hypertension, diabetes, or obesity. However, to preserve their bioactivity, the use of appropriate extraction technologies is required. Method: The present review aims to describe the studies published so far on the essential oils focusing on their sources and chemical composition, the technologies used for their recovery and their application as antioxidants in food products. Results: The review has been structured in three parts. In the first part, the main compounds present in essential oils extracted from medicinal plants have been listed and described. In the second part, the most important technologies used for extraction and distillation, have been presented. In detail, conventional methods have been described and compared with innovative and green technologies. Finally, in the last part, the studies related to the application of essential oils as antioxidants in food products have been reviewed and the main findings discussed in detail. Conclusions: In summary, an overview of the aforementioned subjects is presented by discussing the results of the most recent published studies.

Traditional Persian Medicine

Background: Cough is one of the most common medical symptoms for which medical advice is sought. Although cough is a protective reflex responsible for clearing the airways from secretions and foreign bodies, it can be a troublesome symptom that causes discomfort to patients. Due to the increasing interest in herbal remedies in the both developed and developing countries, in the current study, we aimed to overview medicinal herbs containing essential oils used as antitussive agents according to the Traditional Persian Medicine [TPM] textbooks. We summarized the relevant scientific evidence on their possible pharmacological actions. Methods: To collect the evidence for treatment of cough or “seaal” [cough in ancient books] from TPM sources, five main medicinal Persian manuscripts were studied. The antitussive herbs were listed and their scientific names were identified and authenticated in accordance with botanical reference books. ScienceDirect and PubMed online databases were searched for related mechanisms of action of the reported medicinal plants. Results: The number of 49 herbs containing essential oils were recommended in TPM for the treatment of cough; 21 of them had at least one known mechanism of action for cough suppression in the scientific literature. According to this review, most of the cited medicinal plants were assessed for either nitric oxide inhibitory or antitussive/expectorant activities. Conclusion: In addition to advantageous effects of antitussive herbs noted by TPM, the present review highlighted some recent evidence-based data on these promising candidates that could be used as an outline for future research on their medicinal use.

Crop System

Parasitoids are currently considered for biological control of the spotted wing drosophila (SWD) in berry crops. Releases of mass-reared parasitoids require the presence of all resources necessary to ensure their effectiveness in the crop system. The use of floral resources to feed Trichopria drosophilae, one of the candidate species, was investigated in a laboratory study. The life expectancy of males and females increased by three to four times when they had access to flowers of buckwheat or of two cultivars of sweet alyssum. Female realized lifetime fecundity increased from 27 offspring/female exposed to water only to 69 offspring/female exposed to buckwheat flowers. According to this almost threefold increase in parasitoid fitness, it is advisable to introduce flowering plants into the crop system, when parasitoid releases are carried out. Sweet alyssum offers the advantage of not growing too tall in combination with an extended blooming. However, adult SWD were also able to feed on flowers of both plants and survived for at least 27 days, much longer than starving flies. The introduction of flowering plants to promote natural enemies therefore requires further consideration of the risk–benefit balance under field conditions to prevent unintended reinforcement of this pest.

Gaultheria Procumbens

As part of our evaluation of essential oils derived from Native American medicinal plants, we have obtained the essential oils of Agastache foeniculum (Pursch) Kuntze (Lamiaceae), Gaultheria procumbens L. (Ericaceae), Heliopsis helianthoides (L.) Sweet (Asteraceae), Liatris spicata (L.) Willd. (Asteraceae), Pycnanthemum incanum (L.) Michx. (Lamiaceae), Smallanthus uvedalia (L.) Mack. ex Mack. (Asteraceae), and Verbena hastata L. (Verbenaceae) by hydrodistillation. The essential oils were analyzed by gas chromatographic techniques. The essential oil of A. foeniculum was dominated by estragole (88–93%), while methyl salicylate (91%) dominated the G. procumbens essential oil. Germacrene D was the major component in H. helianthoides (42%) and L. spicata (24%). 1,8-Cineole (31%) and α-terpineol (17%) were the main compounds in P. incanum essential oil. The essential oil of S. uvedalia showed α-pinene (24%), perillene (15%), and β-caryophyllene (17%) as major components. Verbena hastata essential oil was rich in 1-octen-3-ol (up to 29%) and palmitic acid (up to 22%). Four of these essential oils, H. helianthoides, L. spicata, P. incanum, and V. hastata, are reported for the first time. Additionally, the enantiomeric distributions of several terpenoid components have been determined.

Biological control has been reducing the use of chemical products against insect pests, specially predatory Pentatomidae. Species of this group can present high variations in their life cycle as a result of their diet. Thus, the objective of this research was to study nymph development and reproduction of Podisus distinctus (Stäl, 1860) (Heteroptera: Pentatomidae) fed on Bombyx mori L., 1758 (Lepidoptera: Bombycidae) larvae (T1), compared to those fed on Tenebrio molitor L., 1758 (Coleoptera: Tenebrionidae) (T2) and Musca domestica L., 1758 (Diptera: Muscidae) larvae (T3) at a temperature of 25 ± 0.5ºC, relative humidity of 70 ± 2%, and photophase of 12 h. Predators fed on B. mori showed duration of the nymph phase (18.68 ± 1.02) similar to those fed on T. molitor (18.32 ± 1.49). Pre-oviposition and oviposition periods and number of egg masses, besides eggs and nymphs per female, were higher with B. mori (5.83 ± 2.02; 15.00 ± 7.40; 8.42 ± 1.84; 296.69 ± 154.75; and 228.55 ± 141.04, respectively) while longevity of males and females of P. distinctus was 25.76 ± 16.15 and 35.00 ± 16.15 days with T. molitor, and 20.57 ± 13.60 and 23.46 ± 12.35 days with B. mori, respectively.
