“…Using the same methods, EO of Baccharis sphenophylla Dusén ex Malme produced 66.67 ± 3.33% mortality in the insecticide-resistant strain 'Bayonne', while producing 83.33 ± 3.33% mortality in the susceptible strain 'Ft.Dix', 24 h after treatment [53]. The EO of Schinus molle L. produced 100.0 ± 0.00% (Ft. Dix) and 90.0 ± 5.77% (Bayonne) of mortality 24 h after the treatment [54]. In that sense, O. porosa EO cannot be considered as an effective insecticide against bed bugs.…”

Ocotea porosa (Nees & Mart.) Barroso, commonly known as "imbuia", "canela-imbuia" or "imbuiaamarela" in Brazil, is a tree of the Southern Atlantic Forest. The present study investigates the anatomy of leaf and stem, volatile oil chemistry, as well as cytotoxicity and insecticidal activities of the essential oil of O. porosa. Species identification was achieved by anatomy features, mainly due to paracytic and anomocytic stomata; non-glandular trichomes; biconvex midrib and petiole with a collateral open arc vascular bundle; presence of a sclerenchymatous layer, starch grains and crystal sand in the stem; and the presence of HIGHLIGHTS  The anatomy features were useful for identification of Ocotea porosa.  The major volatile compounds were α-pinene, β-pinene and bicyclogermacrene.  Essential oil of O. porosa was cytotoxic against McCoy, B16F10 and MCF7cell lines.  The cytotoxic mechanism might be related to apoptotic events.  Insert 1-4 highlights no longer than 85 characters.  Insert a highlight no longer than 85 characters.  Insert a highlight no longer than 85 characters. • Insert a highlight no longer than 85 characters.

“…Its feeding behavior makes it a difficult pest to control. It typically feeds at night, whereas, during the day, it hides in the folds of furniture and inside cracks and crevices in both wooden and non-wooden structures [1,2]. It is small to medium-sized (4–12 mm), ovate, dorsoventrally flattened, and of brownish coloration [3,4,5,6].…”

Kadsura coccinea (Lem.) A.C. Smith is an evergreen, woody climbing plant that is widely distributed throughout southwest mainland China. Extracts of this plant are used in traditional Chinese medicine (TCM) for the treatment of various diseases, like cancer and dermatosis, and as an anodyne to relieve pain, while the leaves are used to treat eczema. In the current study, the toxicity of essential oil from its stem (EOKC) was studied against two strains of bed bugs (Cimex lectularius). Essential oil from the plant was obtained by hydrodistillation and analyzed by GC/MS. The major compound identified was β-caryophyllene (24.73%), followed by caryophyllene oxide (5.91%), α-humulene (3.48%), and β-pinene (2.54%). Preliminary screening was performed by topically delivering a 1 µL droplet of the treatments dissolved in acetone. At 24 h after treatment, the EOKC induced mortality rates of 61.9% and 66.7% in the Bayonne and Ft. Dix strains, respectively, at 100 µg/bug. Four major compounds—β-caryophyllene, caryophyllene oxide, α-humulene, and β-pinene—were selected based on their availability and were subjected to topical, residual, and fumigation methods. When applied topically, only β-caryophyllene induced high toxicity in both strains. None of the selected compounds induced significant toxicity in the residual and fumigation methods.

Anticarsia gemmatalis is one of the main pests of the soybean crop, being controlled mainly with agrochemicals. The environmental and health risks, as well as the development of resistance by the pests, has led to the search for alternative control measures, aiming to use more eco-friendly procedures. The objective of this research was to evaluate the chemical composition and the bioactivity of Schinus molle and Schinus terebinthifolia essential oils (EOs) on A. gemmatalis. The major compound in both EOs was α-pinene (60.04 wt.% for S. molle and 38.49 wt.% for S. terebinthifolia). Bioassays were carried out with third instar larvae, with five replicates and each replicate with ten larvae, totaling 50 larvae per treatment. The oils were incorporated in the artificial diet (0.1, 0.5, 1.0, 1.5, and 2.0% v/v). The controls were: water, Tween-80 ® 0.5% v/v, and novaluron 0.075% v/v. According to the Probit method, the S. terebinthifolia EO presented a LC50 of 1.74% v/v (1.58-1.97% v/v); it was not possible to determine the LC50 for the S. molle EO. The mortality percentage after 24 and 48 h was 52% and 30% at 2.0% v/v for S. terebinthifolia and S. molle oil, respectively. HIGHLIGHTS  S. molle leaf had an EO yield of 0.3% m/v; S. terebinthifolia had 0.2% m/v.  Both EOs presented α-pinene as the major compound.  S. molle EO induced 30% mortality of A. gemmatalis in 72 h.  S. terebinthifolia EO induced 70% mortality of A. gemmatalis in 72 h.  The LC50 for S. terebinthifolia EO was 1.74% v/v (1.58-1.97% v/v). 2 Vicenço, C.B.; et al.
