Abstract:
Market gardening, one of the predominant activities in developing countries in general and in
Cameroon in particular, is nowadays threatened by pests of several animal taxa. These pests
cause important yield losses and impose frequent and anarchical applications of large spectrum
pesticides that alter product and environment quality. In the perspective of designing a study
program on the ecology of major pests of cultivated cucurbit-based agrosystems, the present
study aimed at assessing the biological diversity of the invertebrate circulating in these
agrosystem. Data were collected at Minko'o, South Region of Cameroon by visual observations
in experimental trap gardens from 2015 to 2017. A total of 412 species of 117 families and 20
orders of Invertebrateswere identified from a set of 40,741 individuals. This sample comprise
Insecta (13 orders), Diplopoda (two orders) and Arachnida (3 orders) and two orders of
Gastropoda. The numerically most important orders were Hymenopterans, Hemipterans,
Coleopterans,Orthopterans, and Lepidopterans representing 88.67% of the total abundance.
Thenumerically dominant species belonged mainly to these orders. In relation with host plant
preferences, all these orders, families and species showed variable level of selectivity as
comparisons of their distribution among studied plantsappeared different from one taxon to
another |
