The research has been conducted in the pilot farm into the selected area of Sant＇Antioco where the first hypothesis has been tested and the information about larval development has been collected. During the whole experimental period have been collected all the data about captures in the black light traps and captures in the soile traps. Experimental data first of all have been emphasize the possibility of decrease the larval reproduction extremely in the alkalized sites then have allowed to study the Bluetongue vectors density closely and its relation with the disease prevalence in the heads presents in the near farms. The results revealed the different distribution of the disease prevalence in the several farms, referable to minute variation of the farm location. In the end it seems essential to improve the farm management through the widespread action of awakening to farmers.展开更多

Three cribs were constructed and 180 kg maize in two bags treated with 1.6% pirimiphos methyl and 0.3% permethrin stored in one. In the other, a similar quantity of untreated maize in two bags was stored while in the third crib, 4 bags of cob maize were placed. Another four bags, two treated and two untreated were placed on dunnage separated by a 2-meter path in the living house. Samples were analysed at 4-week interval for 24 weeks and pest damage was used to calculate percent weight loss. Grain from selected farmers was also analysed for comparison. Crib trial had 53% and 20% pest damage in untreated and treated maize compared with 56% and 16% for in-house storage after six months. Cumulative weight loss averaged 20.6% and 9.7% for untreated and treated maize. The figures are markedly higher than 5% criterion for effective pest control measures. Weight loss on farmer stocks compared well with untreated maize and grain damage varied from 5.4% to 27%, translating to 0.5% and 16.8% cumulative loss. These results suggest ineffective pest control measures by Bungoma farmers. The results contrast with Kitui ones in an earlier study where Prostephanus truncatus is endemic and contributed to 10% cumulative loss above the Bungoma level. Efforts should be made to reduce grain damage to below 5% to realise food security at farm level.展开更多
