<p>Indonesia has numerous and varied natural resources of spices plant which grow at almost all theregions. These plants can grow and adapt to the slightly diverse agroecological conditions and agroecosystems, from dry to wet. In general, the utilization of these plants by the community is still limited as ingredients and spices for culinary and flavoring instead of the potential of bioactive compounds contained therein. These resourcesare very useful and effective utilized asbioinsecticides to eradicate plant pests and diseases, as well as medicine for human. This paper discussed the benefits and efficacy of several spiceplants, namely lemongrass, shallots, garlic, sweet and chili peppers, clove, sand ginger (kencur), and pepper as herbicides at various levels of dosage and treatments. This manuscript also discussed the constraints and development strategies, and aimed to provide information on the science and technology in controlling the Sitophilus zeamais (Motsch) pests in corn kernels during the storage period. It is expected that this paper would be useful for the policy makers, academicians, researchers and practitioners who have the competence to deal with beetle pest problems.</p><p>Keywords: Spices, bioinsecticides, Sitophilus zeamais (Motsch), controlling</p><p> </p><p><strong>Abstrak</strong></p><p>Tanaman rempah yang tumbuh di hampir seluruh wilayah Indonesia sangat beragam.

Sitophilus Zeamais Motsch

Chemical control of the maize weevil (Sitophilus zeamais) has been ineffective and presents serious collateral damage. Among plant-derived insecticides, essential oils (EOs) are suitable candidates to control this stored products pest. In this work, the insecticidal activities of 45 natural EOs against S. zeamais adults were screened, and the most promising ones (24 EOs) were characterized by GC–MS. The repellent and toxic effects (contact and fumigant) of these 24 EOs were determined, and by a cluster analysis they were classified into two groups considering its fumigant activity and contact toxicity. For the EOs with the highest fumigant potential (14 oils) and their main active constituents (17 compounds), lethal concentrations were determined. The most active EOs were those obtained from L. stoechas and L. alba, with LC50 values of 303.4 and 254.1 µL/L air and characterized by a high content of monoterpenes. Regarding the major compounds, the oxygenated monoterpenes R-(+)-pulegone (LC50 = 0.580 mg/L air), S-(-)-pulegone (LC50 = 0.971 mg/L air) and R-(-)-carvone (LC50 = 1.423 mg/L air) were the most active, as few variations in their concentrations significantly increased insect mortality.

Sitophilus zeamais Motsch. is a primary storage insect pest damaging maize grains. Control of S. zeamais can be done by applying biopesticide. This study was aimed at assessing the ability of Jeruk Purut leaf extract, as biopesticide, to kill and repel Sitophilus zeamais Motsch. The study was conducted at Entomology Laboratory, Seameo Biotrop in March to August 2018. A completely randomized design with three replicates in each rate of Jeruk Purut leaf extract was used. In preliminary pesticide toxicity experiment, five rates of Jeruk Purut leaf extract, namely 0%, 2%, 4%, 6%, and 8% were applied. In preliminary repelling ability experiment, five rates of Jeruk Purut leaf extract, namely 1%, 2%, 4%, 6%, and 8% were applied. In the main pesticide toxicity and repelling ability trial, five rates of Jeruk Purut leaf extract, namely 3%, 6%, 9%, 12%, and 15% were applied. Results showed that in 24 hour after treating (HAT) no significant effects were found. Significant effects of Jeruk Purut leaf extract as insecticide on S. zeamais were found in 48 and 72 HAT. The highest mortality rate (82.2%) of S. zeamais was found in 15% rate of Jeruk Purut leaf extract in 72 HAT. The application of Jeruk Purut leaf extract was not found to give significant effects on repelling S. zeamais in 24, 48, and 72 HAT as indicated in their sharply fluctuating repellent values. The highest repelling ability (95%) was found in the application of 9% Jeruk Purut leaf extract in 24 HAT. It was concluded that Jeruk Purut leaf extract was more potential as insecticide repellent for Sitophilus zeamais Motsch.

Experiments were conducted to find out the role of maize weevil, Sitophilus zeamais Motsch. on spread of green fungus, Aspergillus section flavi, in different varieties of stored maize in laboratory in 2016. Lab experiment was conducted to find the role of weevil on spread of A. flavus on five main varieties of maize grown at Nepal in split plot design, namely, Arun-2, Arun-4, Manakamana-1, Manakamana-3, and Rampur composite with three replications at NAST, Khumaltar, from August to September 2016. One hundred grams of each maize variety was exposed to weevil along with fungus and with fungus only to see the spread of the fungus under presence and absence of weevil. Among the tested five maize varieties, the lowest infestation was observed on Rampur Composite (14.99%) while it was the highest on Manakamana-3 (87.70%). The highest mean infestation (75.58%) was found under weevil released condition while it was lower (62.16%) under nonreleased condition. In presence of weevil, the infestation of the fungus increased and in their absence the infestation was low which signifies the role of weevil in fungal spread. All indices indicate that Rampur composite is the best variety among the five tested varieties in terms of storage under the presence of fungus and weevils. This study also indicates ample scope for further study on different varieties of maize under several storage conditions.

Laboratory studies were conducted to investigate the repellency effect of six plant species (Azadirachta indica, Caralluma fimbriata, Allium sativum, Curcuma longa, Citrullus colocynthis and  Calotropis procera) against Sitophilus zeamais reared on maize grains (Cv. Azam White) in the Laboratory of Entomology Department, Gomal University, Dera Ismail Khan, Pakistan. Six concentrations viz. 5000, 10000, 15000, 20000, 25000 and 30000 ppm of each plant powder were applied to 20 g of sterilized maize grains under constant conditions of 27 ± 1°C and 65 ± 5% relative humidity. Twenty newly emerged adult maize weevil were introduced into glass petri dishes and percent repellency of plant powders was determined. A. indica seed powder  at 30,000 concentration showed 100% repellency against maize weevil followed by C. longa  (76%)  after 72 h exposure period whereas C. procera was found least effective showing only 39% repellency of the test insects compared to control. The powders of A. sativum, C. fimbriata were found moderately repellent against the test insects. During the observations, it was also noted that repellency of the tested plant powders was dose dependent, the higher the concentration of the tested powders, the higher was the repellency and vice versa. The findings of this study indicated that the selected plant products could be used for a safer control of maize weevil.

Laboratory experiment was done to perform the phytochemical screening of six locally available botanicals (Azadirachta indica Juss, Artemisia dubia Wall, Lantana camara L, Parthenium hysterophorus L, Justicia adhatoda Linn. and Moringa oleifera L.) and their effectiveness to control the maize weevil (Sitophilus zeamais Motsch.) at Agriecology lab of Institute of Agriculture and Animal Science, Paklihawa Campus, Rupandehi, Nepal. Seven treatments (leaf extract of A. indica, A. dubia, L. camara, P. hysterophorus. J. adhatoda and M. oleifera and distilled water as control) applied at 3 different doses (0.5, 1 & 2g/50g seeds) were arranged in CRD design with 3 replications. Result of mortality test of maize weevil revealed that, at highest concentration of L. camara powder (T17- 2g/50 gm seeds) mortality of maize weevil was observed up to 85% at 45 DAT. Whereas number of damaged grain was lowest in T17 (L. camara powder- 2g/50 gm seeds). The effectiveness of botanicals was found to increase with increasing the concentration. Besides that, Justicia adhatoda (2g/50g seeds) and Artemisia dubia (1g/50g seeds) were also found as good candidates to use for the control of Sitophilus zeamais. Qualitative tests done for the presence of various phytochemicals showed that Azadirachta indica Juss and Artemisia dubia Wall. were found to contain most of the tested metabolites among all botanicals. Most of those phytochemicals were extracted by the aqueous solution rather than other 3 menstrums used (acetone, methanol and petroleum ether). Similarly, quantitative test revealed that percentage of alkaloid was found 18.01%, 17.78%, 17.75%, 11.58%, 8.20%, 6.78% and flavonoid15.32%, 13.63%, 12.86%, 11.36%, 7. 51% 2.85% respectively in L. camara L. P. hysterophorus L., J. adhatoda Linn., M. oleifera L., A. indica Juss. and A. dubia Wall. Leaf extract of L. camera found to contain highest botanicals extract reach in alkaloid and flavonoid mayhave insecticidal property and could be use as grain protectant percentage of alkaloid (18.01%) as well as flavonoid (15.32%) So, it was concluded that the locally available against the maize weevil at storage condition in cost effective and eco-friendly manner; however, application at proper dose is necessary to maintain the efficacy at higher level.
