“…Also, wheat seed might be infested by storage pests (insects and fungi) or might refer to the increase of consumption of some organic compounds in respiration process with increasing storage periods which leads to increasing dry weight loss of seed. These results are in agreement with those reported by many authors such as [25,29,46,47,50,51].…”

This experiment was conducted at the laboratory of Seed Technology Sakha Agricultural Research Station, Kafr EL-Sheikh, Egypt, during the period between 2018 and 2019 seasons. The aim of this study was to evaluate the effect of packages types and some treatments on wheat seed during storage. The experiment was designed in factorial experiment in completely randomized design with four replicates. The samples were treated with the recommended dose of malathion, recommended rate of phosphine, the powders and extracts of each of (ficus, camphor, clove), the powder of copper nanoparticles and untreated seed as a control treatment. Treated seed were stored in different packages (Jute, Plastic and Polyethylene) for 18 months. The most important results can be summarized as follows: Increasing storage periods of wheat seed up to 18 months significantly affected storage efficacy, vitality and quality of wheat seed. The best results of storage efficacy of wheat recorded when seed stored in polyethylene packages, followed by seed stored in jute packages and lastly stored in plastic packages. Seed treated with copper nanoparticles were the best in germination percentage, electrical conductivity, acidity, protein percentage, carbohydrate percentage, relative density and 1000-seed weight. While treatment with malathion was the best in acidity, relative density, 1000- seed weight and insect infestation percentage. As for phosphine, it was the best in moisture percentage, insect infestation percentage and weight loss percentage. This study recommended that treated seed with copper nanoparticles before storage and stored it in polyethylene packages under the environmental conditions of the experiment in Sakha, Kafr EL-Sheikh, Egypt.

From April to July 2019, an experiment was conducted in Khumaltar, Lalitpur (27°39.312′N, 85° 19.586′E, and 1322 m above sea level) to assess the effectiveness of plant materials on maize weevil (Sitophilus zeamais Motsch.) control under laboratory conditions (maintained room temperature of 28.5 ± 2°C, and relative humidity of 72 ± 5%) treatments were Acorus calamus (rhizome powder) @ 5 g·kg−1, Melia azadirach (rhizome powder) seed) @ 5 g·kg−1, Curcuma domestica (rhizome powder) @ 5 g·kg−1, mustard oil @ 2 mL·kg−1, Gingiber officinalis (rhizome powder) @ 5 g·kg−1, rice husk ash @ 5 g·kg−1, and an untreated control. These treatments were evaluated in a completely randomized design (CRD) with three replications. At four months, the grains treated with Acorus calamus had the least weight loss (6.66%), and grain damage (1.23%). Grain damage (18%), and weight loss (62.33%) were the highest in the control treatment. Similarly, grains treated with Acorus calamus had the fewest number of exit holes (3.10 per 100 g of maize seed), while the control treatment had the largest number of exit holes (45.10 per 100 g of maize seed). There was a significantly higher number of weevils in the control treatment (55.80 per 250 g maize grains), but only a few numbers of weevils in the Acorus calamus-treated grains (2.50 per 250 g maize grains). In contrast with other plant materials treated grains, the maize weevil showed a reduced preference for Acorus calamus- treated grains with low weight loss, and grain damage. These findings can be used to promote locally accessible botanicals for maize weevil control in Nepal.

“…They also reported that grain storage in aluminum container with A. calamus dust treatment was 28 times better than jute bag without botanical treatment (82.5%) in term of grain damage. Padmasri et al (2017) reported that seeds treated with A. calamus rhizome powder @ 10 g/ kg seed had recorded highest germination percentage (85.67), seedling vigour index (2354), less infestation (0.18%) and weight loss (0.02%) at the end of 9 months of storage at Seed Research and Technology Centre (SRTC), PJTSAU, Rajendranagar, Hyderabad during 2015/16. Some of the promising botanicals against S. zeamais are listed below in Table 4.…”

The maize weevil Sitophilus zeamais Motschulsky (Coleoptera:Curculionidae) is an important pest of maize in storage in term of losses caused in food quality and quantity in Nepal. Attempt made to review bionomics and management practices of this pest gleaning published literatures/papers on national and international journals, proceedings, reports, newsletter and books. The paper discusses on nomenclature, morphology, distribution, biology and ecology of maize weevil and provides prospect of using various physical, sanitary, cultural, botanical, biological and chemical control measures to manage weevil. This information is useful to personnel involved on agricultural research and development for developing location specific integrated pest management approach of this pest. Finally, it also shows importance of farmers’ awareness on pest biology and ecology, appropriate maize harvesting time, storage structures and post-harvest handling practices to reduce losses in maize storage.
