“…[68] extensively discussed the combined use of pirimiphos-methyl and permethrin or fenitrothion and fenvalerate to control the pest complex consisting of P. truncatus, Sitophilus sp., and T. castaneum. Gourgouta, et al [69] found that a commercial cypermethrin formulation was effective against S. oryzae, O. surinamensis, R. dominica, and P. truncatus infesting wheat and maize. Various fumigants have also been employed for grain fumigation to combat storage pests.…”

COVID-19 poses a significant threat to the present and future of mankind. The emergence of diverse strains during the pandemic creates uncertainty regarding their disappearance or resurgence. Lockdown measures and travel restrictions impact national and household food systems, hindering the movement of people and goods. Effective COVID-19 control requires science-based preventive measures and consideration of food availability. In Tanzania, resource-constrained farmers rely on the self-storage of food crops. Precise pest control information and tailored detection/storage systems are essential for preserving major staple foods such as maize and beans, which face frequent infestation by beetles and moths. Traditional methods used before the pandemic are insufficient compared to advanced global alternatives. This paper reviewed about 175 publications from different databases, dated from 1984 to 2023 (2023 to 2014 = 134, 2013 to 2004 = 26 and 2003 to 1984 = 15), assessing storage management for maize and beans. Identifying gaps between Tanzania and global advancements aiming to empower farming communities with the latest technologies and ensuring food security amid the pandemic.

“…[13][14][15] due to their relatively low toxicity to mammals and humans [16]. Furthermore, they are commonly used to replace older or banned insecticides in stored product protection [17,18]. Phosphine is currently the most common fumigant in stored product protection globally [19].…”

The protection of stored products from insect pests is mainly based on suppressive methods by using contact and gaseous insecticides, globally. Following their continuous and improper use, insecticide resistance has been observed in several major insect species and pose a continuous threat to the sustainability of a wide range of active ingredients that are currently in use in stored product protection. In the present work, on-site samplings of insect populations were carried out in local warehouses containing different types of cereals. The collected insects, Rhyzopertha dominica (F.) (Coleoptera: Bostrychidae), Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae) and Cryptolestes ferrugineus (Stephens) (Coleoptera: Laemophloeidae), were reared under laboratory conditions to determine tolerance/resistance to widely used insecticides, using different diagnostic protocols. Laboratory populations of the same species were also examined for comparative purposes. Adult knock down and mortality of all populations indicated different patterns of tolerance to phosphine, deltamethrin, cypermethrin, and pirimiphos-methyl. In many cases, the recommended label doses were not able to completely control some of these populations, regardless of their origin, i.e., field-collected or laboratory. The results of the present work underline the importance of population on the efficacy of insecticides that are currently in use in stored product protection.

BACKGROUND Mediterranean flour moth or mill moth Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) is a common pest of cereals and flour throughout the world. In this study, eggs, third instar larvae, pupae and adults of E. kuehniella were exposed to five elevated temperatures at a range of 45 to 65 °C for 5, 8, 10, 14, 18, 23 and 30 min. The effect of cypermethrin and dichlorvos was assessed on third instar larvae. The larvae were exposed to the insecticides on glass and concrete arenas and their mortality was recorded 24 h after treatment. To determine combination effects, the third instar larvae were transferred into the Petri dishes treated with LC25 (lethal concentration that kills 25%) of each insecticide and exposed to high temperatures for the period of time equal to LTi25 values (time needed for killing 25% of tested insects). RESULTS Exposing the eggs, third instar larvae and adults of E. kuehniella to 55 °C for 30, 18 and 30 min respectively, resulted in 100% mortality. In the pupa, exposure to 65 °C caused 100% mortality after 23 min. Based on the LTe50 values (temperature needed to cause 50% mortality in the tested population), pupa was the most tolerant life stage to the temperatures tested. The LC50 values of cypermethrin and dichlorvos were 423.1 and 2608.5 mg active ingredient (a.i.) L−l on glass, and 2525.0 and 13502.8 mg a.i. L−l on concrete, respectively. The effect of cypermethrin was synergized by high temperatures. CONCLUSION High temperatures, cypermethrin and dichlorvos were effective against E. kuehniella. Exposure to combination of lower doses of cypermethrin and high temperatures at short time intervals may have potential in managing this pest. © 2021 Society of Chemical Industry.
