Efficacy of varying amounts of five selected local plant namely : Balanite aegyptiaca, Eugenia aromatica, Piper guineense, Ocimum gratisimum, and Ziziphus mauratania against the mortality, oviposition, progeny emergence and  weight loss of dried fish due to infestation by  Dermestes maculatus was studied under ambient conditions. The plant were pulverised into powders and applied as 2.0, 4.0 and 6.0 g per 50 g of dried fish. Three pairs of newly emerged adults by  were inoculated into each of the treated fish in a beaker, arranged in a Complete Randomized Design  in the laboratory. The result showed all the plant powders tested evoked significant mortalities of adults at the highest concentration (6) after 3 and 7 days of post-treatment when compared with untreated control. The rate of oviposition was drastically suppressed by all plant powders, especially at higher concentration.  The number of adults emerged were significantly lower than control at (p>0.05).  Similarly, all the plant's powders significantly prevented weight loss at highest concentration after 12 weeks of post-treatment periods. These results have shown that tested plants demonstrated potential ability against adults hide beetle infesting dried fish.

Piper guineense fruits were purchased, sun-dried (30±2oC) for 10 days and ground into fine powder. Fifteen (15) pieces of Clarias gariepinus (300 ± 5.0 g) were procured and smoke-dried in the laboratory using a charcoal-powered smoking kiln at 65oC for 10 hours. Each smoke-dried fish sample was placed in a plastic container with perforated lids covered with muslin cloth and Piper guineense fruit meal was sprinkled at varying quantities (0.0 g, 2.5 g, 5.0 g, 7.5 g and 10.0 g). Ten (10) adults of Dermestes maculatus bred from highly infested smoke-dried fish samples were introduced into each container and covered air-tight for seven (7) days. Mortality of D. maculatus was significantly different (p = .05) in all treatments and increased with an increase in the quantity of P. guineense and number of days. Mortality ranged between 73.33 and 100 % in treated groups while none was recorded in the control. Chemical compositions in treatments showed an increase in crude protein, lipids and lower moisture content at higher inclusion levels. This study showed that P. guineense can prolong the shelf-life of smoke-dried C. gariepinus against D. maculatus while retaining its nutritional composition.

Synthetic pesticides used to protect stored smoked and dried fish often cause enormous damageto human health and the environment. To limit the harms due to the use of these chemicals, it is necessary to find alternative methods. For this purpose, natural substances may constitute a beneficial way. The objective of this work is to study the effect of crushed fresh leaves and essential oil of Eucalyptus camaldulensis on the mortality of the larvae of an insect pest of smoked and dried fish, Sardinella aurita "Kétiakh", Dermestes maculatus (De Geer, 1774). Essential Oil was obtained by steam distillation from Eucalyptus leaves (0.8% w/w) and analyses carried out by GC/FID and GC/MS. For the biological test, fresh crushed leaves and essential oil were tested at different doses at varying treatment times again larvae Dermestes maculates. The results showed that D. maculatus was sensitive for both fresh crushed leaves and the essential oil, the efficacy of which depended on the dose and duration of treatment. The doses of 2 g and 2.5 g of freshly ground leaves showed a high efficiency of 27 to 40%, of mortality respectively. However, for the essential oil, with the increase in the duration of exposure, the highest mortality (33.3%) was recorded after 72 hours of treatment with the 40µl dose and at 120 hours with the 60µl dose. This study showed that fresh crushed leaves and essential oil of Eucalyptus camaldulensis can be considered as an alternative to the use of chemical insecticides in the conservation of smoked and dried Sardinella aurita "Kétiakh" stored in Senegal.

And Storage

Infestations of Dermestes maculatus Deg. in dried fish at Dugbe market, Ibadan, are favoured by traditional packaging and display methods. In laboratory experiments last-instar larvae and adults showed low thigmokinesis and a bias towards the dry end of a 50–100% r.h. gradient; in alternative humidities between 40% and 100% last-instar larvae and adults selected 60–80% r.h., adults having a stronger preference than the larvae for the higher humidity; in a temperature gradient last-instar larvae and adults avoided the 30–45° C zone and showed low thigmokinesis and immobilisation at 19° C. These findings were generally consistent with observations in the market. Heating dried fish in an oven at 60° C for 30 min killed all larvae and adults of D. maculatus present. Two 30-min heat treatments at four-day intervals in a simple charcoal-fired oven and storage in metal containers would control the pest.
