“…It was found that the cinnamon methanol extract showed the highest repellent effect against rice weevils during each exposure times interval (6 h) at a concentration of 10 mg/mL. In another study, when tested with the extract of Amomum cardamomum under various concentrations (25%, 50%, 75%, and 100%), the highest repellence activity on adult rice weevils was observed at the highest concentration (100%) after 1 h treatment time (Widiyaningrum et al, 2019). A comparison of this study proves that increments in time and concentration positively affect the repellency of wood vinegar and other plant extracts which scientifically represents the actions of chemical constituents' present.…”

Rice production faces many challenges including damages due to pest infestation in storage after harvest. Stored rice grains are often under threat and damage from pests such as rice weevil which resulted in reduction of the quality and quantity. Application of chemical insecticides helps to control this pest, however, it gives negative impacts to the environment and human health. Application of plant-based insecticides including the use of wood vinegar can become an alternative to the conventional method. This work describes the effectiveness of wood vinegar as bioinsecticide to inhibit the rice weevil’s activity by assessing the repellency, mortality and antifeedant activity at different concentration of 50, 100, 150 and 200 rpm. Wood vinegar showed high repellency of 98.3% towards rice weevils at 200 ppm after 5 hours of exposure times. Increased in concentration affects in increased mortality with highest number of 97% recorded at 200 ppm. The lethal concentration (LC) of wood vinegar was calculated to be 77.62 ppm. Antifeedant activity resulted in reduction of weight loss in stored rice with lowest reduction of 2% at 200 ppm. This promising result reflects the ability of wood vinegar as insecticidal agents in management and control of stored-grain pest.

“…A group of plants reported having insecticidal activities are plants from Zingiberaceae family. Studies on secondary metabolite from plant rhizomes reveal that the members of Zingiberaceae which have the potential as a source of natural insecticides are turmeric rhizome (Curcuma longa) 10 , ginger (Officinale zingiber) 11 , cardamom (Amomum cardamomum) 12 , galangal (Alpinia galanga) 13 and bitter ginger (Zingiber zerumbet) 14 . However, the rhizome of medicinal plants generally has high selling value as raw materials for spices and herbal medicines, so they are less economical if used as a source of botanical insecticides.…”

Background and Objective: At present, insecticides with raw materials of active compounds from plants have become a strategic alternative, because they are easily obtained and produced. In an attempt to find natural and cheaper methods for the control of rice weevil (Sitophilus oryzae L.), some useless waste of local medicinal plant extracts was evaluated. This study aimed to evaluate the antifeedant effect of various medicinal plant extracts on rice weevil (Sitophilus oryzae L.). Materials and Methods: The experimental study using a completely randomized design of two factors, i.e., source of the extract in 7 types of medicinal plant waste and the exposure time of extracts in 0, 1, 2 and 3 h. The antifeedant effects were evaluated after 3 weeks by measuring feed consumption (FC), feeding deterrent index (FDI) and rice weevils' mortality. Data were analyzed using variance analysis. Results: The statistical analysis showed that the differences in exposure time contributed significant influence ("<0.05) on FC, FDI and mortality. The lowest FC occurred at the 3 h exposure treatment, i.e. on the extract of Amomum cardamom plant, while the highest FC was found in the treatment of Curcuma mangga plant extract. The values of FDI and mortality at the 3 h extract exposure were 31.53-87.16% and 42.4-64%, respectively with the highest value in the treatment of A. cardamomum. Conclusion: At last, these findings inform peoples that the waste of medicinal plants, especially cardamom is possible to be developed as botanical insecticides for rice weevils.

In an attempt to found natural and cheaper methods for the control of rice weevil, waste extract from two local spices plant were evaluated. Ethanol extracts (mix of leaf and stem parts) of Zingiber zerumbet and Amomum cardamomum were tested on rice weevil for their insecticidal effect. The rice weevil was treated under four different exposure times (0, 1, 2, and 3 hours) and then maintained for 3 weeks in the rice storage. The difference in weight loss of rice (WL) was assumed as feed consumption, and it was an indicator of the insecticidal effect. Percentage of WL were analyzed using ANOVA. The results showed that exposure time was significant to WL on both extracts (LSD test; α < 0.05). The insecticidal effect with the lowest WL of rice occurred in a 3-hour treatment. The percentage WL in A. cardamomum is lower than those in the Z. Zerumbet. In conclusion, both plants’ waste extract decreased the feeding activity on the rice weevil, but the waste extract of A. cardamomum is more effective than Z. zerumbet. This study demonstrates that a waste extract of A. Cardamomum has potency as an insecticide for rice weefil, when appropriate formulation and application methods have been developed.
