Article
Full-text available
The performance of six grain storage technologies for the control of insect pests in maize was evaluated over a 36-week (9-month) storage period. The six technologies used were: two ZeroFly® hermetic bag brands (laminated and non-laminated); Purdue Improved Crop Storage (PICS) bag; non-hermetic ZeroFly® bag; woven polypropylene (PP) bag containing...
Article
Knowledge of the role of hygiene in reducing food loss in farm stores is limited among extensionists, researchers, and farmers. Store hygiene practices during post-harvest handling and storage of maize were assessed using a cross-sectional survey of 342 farmers, with regular follow-up of 40 farmers' stores over seven months to measure losses caused...
Article
Full-text available
Hermetic technologies are being promoted in Africa as safer and more effective methods of grain storage on smallholder farms. However, farmers and policy makers lack knowledge of their efficacy in controlling major stored grain pests. An on-station study was conducted to evaluate the triple layer Purdue Improved Crop Storage (PICS) airtight bags ag...

The fall armyworm (FAW), Spodoptera frugiperda, threatens maize production in Africa. A survey was conducted to determine the distribution of FAW and its natural enemies and damage severity in Ethiopia, Kenya and Tanzania in 2017 and 2018. A total of 287 smallholder maize farms (holding smaller than 2 hectares of land) were randomly selected and su...
Article
Full-text available
Maize ( Zea mays ) is an important staple food crop produced by the majority of smallholder farmers that provides household food security through direct consumption and income generation. However, postharvest grain losses caused by insect pests during storage pose a major constraint to household food security. Hermetic storage technology is an alte...
Article
Full-text available
The fall armyworm (FAW), Spodoptera frugiperda, is a major pest of maize in North and South America. It was first reported from Africa in 2016 and currently established as a major invasive pest of maize. A survey was conducted to explore for natural enemies of the fall armyworm in Ethiopia, Kenya and Tanzania in 2017. Smallholder maize farms were r...
Article
Full-text available
This paper reports for the first time on farmers’ knowledge, perceptions and management practices of the fall armyworm (Spodoptera frugiperda) in Ethiopia and Kenya. A survey of 343 smallholder maize farmers was conducted. Most farmers in Ethiopia and Kenya had knowledge about fall armyworm; they could identify it mainly during its larval stage. Fu...
Article
Full-text available
On-farm trial with a total of 32 farmers in eight villages of Naivasha and Nakuru areas of Kenya was conducted between December 2013 and September 2014 to evaluate hermetic grain storage technologies under farmers’ management conditions. The storage technologies evaluated were metal silo and SuperGrain IV-R bag alongside the standard woven polyprop...

Laboratory bioassay trials were conducted at the National Agricultural Research Laboratories and Kiboko sub-centre in Kenya to determine the efficacy of spinosad dust 0.125% admixed with shelled grains, compared to a "cocktail" of pirimiphos-methyl 1.6% and permethrin 0.3% (Actellic super dust) against four important storage-insect pests: Sitophilu...
Article
Full-text available
The larger grain borer Prostephanus truncatus Horn and the maize weevil Sitophilus zeamais Motschulsky are important pests of stored maize in the tropics, particularly where maize is stored on-farm with little control of moisture content and without use of pesticides. This study was undertaken to determine level of resistance among new experimental...
Article
Full-text available
A study was conducted with the objectives of assessing comparative grain damage and weight loss in maize due Prostephanus truncatus and Sitophilus zeamais at ten varying population densities (5, 10, 15, 20, 25, 30, 35, 40, 45 and 50 insects per 200 g grain) and three storage durations (30, 60 and 90 days), in a laboratory. The final insect densitie...

Abstract Maize (Zea mays L.) is the most important food crop in the coastal region, particularly in Kilifi and Kwale Districts of Kenya, although maize deficit exists there. Drought stress causes >17% loss in maize grain yields, while attack by weevil (Sitophilus zeamais Motshulky) and the larger grain borer (LGB) (Prostephanus truncatus Horn) caus...
Chapter
These proceedings contain nearly 200 keynote, oral and poster papers and contributions highlighting the work on the pests and diseases that cause spoilage, adverse health effects and crop losses after harvest, and discussing new techniques for safe, effective and environmentally friendly management of stored commodities. The contents cover the futu...

Full-text available
Flight traps with open vertical baffles and refuge traps in the form of rectangular cardboard boxes were used to catch Sitophilus zeamais and S. oryzae in Kenya. Traps baited with the aggregation pheromone (Sitophilure), and for the first time traps baited with pheromone and food bait (cracked wheat), were field tested. Both traps types were effect...
Article
Full-text available
Flight traps and crevice traps for catching Prostephanus truncatus (Horn) and Sitophilus zeamais Motschulsky were studied in Kenya. The traps were baited with pheromones of these beetles, with or without synthetic maize volatiles. In the case of P. truncatus, which has a two component pheromone consisting of Trunc-call 1 (T1) and Trunc-call 2 (T2),...

Three hundred twenty nine samples from different parts of Kenya which had not previously been treated with bio-pesticide were collected for Bacillus thuringiensis isolation. The δ-endotoxin crystals were isolated from nutrient broth culture by medium speed centrifugation. From the colony samples examined, 77.1% (236) were non crystal forming Bacill...
