Abstract One hundred and eighty 7-week-old laying quail were fed various diets over a 12-week period. The diets included a control diet (without essential oil mixture (EOM) or antibiotics (ANTs)), a basal diet including EOM (24mg/kg feed), and a basal diet including an ANT (avilamycin, 10mg/kg feed).

The competency of garlic and pennywort to improve broiler chicken growth and influence intestinal microbial communities and fatty acid composition of breast meat were studied. Two hundred forty, "day-old" chicks were randomly allocated to 4 treatment groups consisting of 6 replications of 10 chicks in each pen.
This is a research-based lecture on the powers of essential oils as biopesticides presented by Nurhayat Tabanca, a natural products research scientist from the University of Mississippi's National Center for Natural Products Research.
In this free ACHS webinar, you'll learn about:
Fungicidal and insecticidal properties of essential oils
How increased resistance to commercially available pesticides has led to a focus on natural pesticides
The advantages of natural products/pesticides: how they target new modes of action with low toxicity to mammals and decompose rapidly to reduce environmental risk
The importance of material sources and GC/MS analysis

Essential oils can be used as an alternative to using synthetic insecticides for pest management. Therefore, the insectistatic and insecticidal activities of the essential oil of aerial parts of Salvia ballotiflora (Lamiaceae) were tested against the fall armyworm Spodoptera frugiperda (Lepidoptera: Noctuidae). The results demonstrated insecticidal and insectistatical activities against this insect pest with concentrations at 80 µg·mL-1 resulting in 20% larval viability and 10% pupal viability. The larval viability fifty (LV50) corresponded to a concentration of 128.8 µg·mL-1. This oil also increased the duration of the larval phase by 5.5 days and reduced the pupal weight by 29.2% withrespect to the control. The GC-MS analysis of the essential oil of S. ballotiflora showed its main components to be caryophyllene oxide (15.97%), and β-caryophyllene (12.74%), which showed insecticidal and insectistatical activities against S. frugiperda. The insecticidal activity of β-caryophyllene began at 80 µg·mL-1, giving a larval viability of 25% and viability pupal of 20%. The insectistatic activity also started at 80 µg·mL-1 reducing the pupal weight by 22.1% with respect to control. Caryophyllene oxide showed insecticidal activity at 80 µg·mL-1 giving a larval viability of 35% and viability pupal of 20%.The insectistatic activity started at 400 µg·mL-1 and increased the larval phase by 8.8% days with respect to control. The LV50 values for these compounds were 153.1 and 146.5 µg·mL-1, respectively.
