“…aegypti, we found that garlic essential oil has a stronger effect than anise essential oil. This result is in line with the previous research [10,21]. Statistical analyses show that the efficiency of garlic and anise essential oils for Aedes larval removal between 24-and 48-h post-exposure was not different, except concerning anise essential oil (which had different value for LC 9O ).…”

“…This result was consistent with the previous biological research, which found that garlic and anise essential oils are toxic to mosquito species including Culex restuans (LC 50 : garlic = 2.7 ppm) and Cx. pipiens (LC 50 : Garlic = 7.5 ppm and anise = 28.7 ppm) [10,21]. According to Öz et al's study [10], anethole has been identified as a major component of anise essential oil (94.48%).…”

“…The garlic plant (Allium sativum), belonging to the family Liliaceae, and anise plant (Pimpinella anisum), belonging to the family Apiaceae, are important components of many foods and contain important substances that are beneficial to human health [6,7]. The previous research has reported that the essential oils of both of these plants are very effective in controlling many insects including the mealworm beetle [8], the cotton leafworm [9], and Culex mosquitoes [10].…”

Aedes aegypti, also called the dengue or yellow fever mosquito, is a significant vector species of several viruses especially the dengue virus. Reducing Ae. aegypti population can directly reduce dengue outbreaks in the community. The research aim is to assess the efficacy of commercial botanical pure essential oils of garlic (Allium sativum) and anise (Pimpinella anisum) against Ae. aegypti larvae, the mortality of larvae was monitored after 24-and 48-h of exposure. The larvicidal activity of garlic oil after 24-h exposure was 0.005 ppm for LC 25 , 0.006 ppm for LC 50 , and 0.012 ppm for LC 90 , and after 48 h exposure was 0.004 ppm for LC 25 , 0.006 ppm for LC 50 , and 0.014 ppm for LC 90. Meanwhile, the larvicidal activity of anise oil after 24-h exposure was 0.016 ppm for LC 25 , 0.023 ppm for LC 50, and 0.043 ppm for LC 90 , and after 48-h exposure was 0.014 ppm for LC 25 , 0.020 ppm for LC 50 , and 0.037 ppm for LC 90 , whereas, Aedes larval mortalities increased with an increase in the concentration of garlic and anise essential oils after both 24-and 48-h exposure. The results of this study were clear evidence for the efficiency of commercial plant oil for dengue vector larval control, especially garlic essential oils.

Concentration effects of chili and ginger extracts against diamondback moth (Plutella xylostella L.) on round cabbage

Diamondback moth (Plutella xylostella L.) is a major pest of cabbage and other vegetables in the Brassicaceae family. The management and control of this cosmopolitan and economic pest has been a challenge in tropical regions. Reliance on chemical insecticides have led to resistance, natural enemy suppression, contaminated residues, risks to chemical poisoning and other environmental contamination. Therefore, the need to utilize non-host spice plants is an alternative. For this study, we focus on different concentration levels of two local spice plants; (1) chili (Capsicum frutescens L.) and ( 2) ginger (Zingiber officinale R.). Based on previous studies, extracts from both plants have been able to reduce pest infestation in vegetables. There were nine ( 9) treatments (T):T8=6ml of pure water L −1 v/v and T9=9ml of pure water L −1 v/v. From these treatments, 6ml chili was effective in lowering the defoliation (%) and was able to produce high leaf area index (LAI) regardless of increasing rainfall. Ginger 9ml produced high LAI and low defoliation in spite of increasing rainfall. Rainfall (mm) was an important environmental factor affecting the abundance, LAI and defoliation.

The ecotoxicological consequences of synthetic pesticides have encouraged stakeholders to search for eco-friendly pest control tools, like essential oils (EOs). Nano-delivery systems (nanoparticles and nano-emulsions) seem ideal for developing EO-based biopesticides, although production processes should be standardized and implemented. In this study, nano-emulsions loaded with a high amount of Allium sativum L. EO (15%) were developed using different mixed bottom-up/top-down processes. Garlic EO was chemically analyzed by gas chromatography-mass spectrometry (GC-MS) and formulations were physically characterized using Dynamic Light Scattering (DLS) apparatus. The insecticidal activity against Planococcus citri Risso (Hemiptera: Pseudococcidae) and selectivity toward Apis mellifera L. (Hymenoptera: Apidae) worker bees was evaluated. Garlic EO was mainly composed of sulphur components (96.3%), with diallyl disulphide and diallyl trisulphide as the most abundant compounds (37.26% and 28.15%, respectively). Top-down processes could produce stable nano-emulsions with droplet size in the nanometric range (< 200nm) and good polydispersity index (PDI < 0.2). In contrast, the bottom-up emulsion was unstable, and its droplet size was around 500nm after 24 hours. High-energy emulsification processes significantly increased the residual toxicity of garlic EO against 3rd instar P. citri nymphs, whereas the developed formulations were harmless to A. mellifera workers in topical application. This study confirmed that the production process significantly affected the physical properties and efficacy against target pests. The lack of adverse impact on honeybees denotated the potential of these formulations as bioinsecticides in organic and/or IPM programs, although further extended ecotoxicological studies are necessary.
