Contribution à la connaissance de la faune associée à la Grande Morelle (Solanum macrocarpon) et au Piment (capsicum annuum) à Yaoundé

Abstract

The Great Morelle (Solanum macrocarpon) and Pepper (Capsicum annuum) appears amongst the market gardening system mostly practice in urban and inter-urban areas in Cameroon. These practices are regularly destroyed by ravagers which attacks the stems, leafs, flowers and even fruits. The present study is a contribution to the knowledge fauna associated to Solanum macrocarpon and to Capsicum annuum has permitted to take out a large number of ravagers. The work was carried out from Febuary to October 2015 on an experimental site found on the campus of ENS Yaoundé. After putting in place the experimental garden, a collect of data was done by inventory and direct observations on Arthropods farm and on their various plants activities. In the second place, to the sampling, to the inventory and direct observations on the field of Arthropods and their activities. We equally proceeded to the evaluation on the lost of fruits. Totally, we have identified 169 Species of Arthropods belonging to 90 Families and 20 Orders. In thiscommunity of ravagers, we can find nocive species and some numbers which are useful (auxiliaries). On the 2 varies of Solanacites, Arthopodofaune was dominated by Hyménopters, Hemipters, Dipters and Coleopters. Certain of them are distinguished by their extreme nuisance on the cultures. Also on Solanum macrocarpon, the most important rupture is being caused by the principal ravagers Leucinodes orbonalis. On Capsicum annuum, the principal ravager is Ceratitis capitata. The direct or indirect dangers are caused by these ravagers represent one of the principal break for a better results, quality produced, its urgent to help the population to adopt methods of protecting more the culture, more respecting the environment and the health of the consumers.
