“…the action of natural insecticides, the reduced efficacy of A. indica extract is similar to the observations ofBarry et al 2017, confirming the argument that neem-based products could be more effective in storage than in the field[11]. The higher efficacy of B. dalzielii extract is due to the adhesive factors such as a gum found in B. dalzielii, which makes it viscous[24], to improve its efficiency. According to Mfuti et al[19], adhesion is an important factor of the effectiveness of a treatment.…”

To promote the use of natural substances for better management of the cowpea thrips Megalurothrips sjostedti, the potential of aqueous extract of Azadirachta indica, Boswellia dalzielii and Metarhizium anisopliae, alone and their combinations in comparison with the synthetic chemical insecticide (Decis) were tested. The experiments were carried out in two cowpea varieties under field conditions within the Sudano-Sahelian agro-ecological zone of Cameroon. Trials were arranged in a completely randomized block design with nine treatments. The nine treatments consisted of a negative control, A. indica; B. dalzielii; M. anisopliae, A. indica+B. dalzielii; M. anisopliae+B. dalzielii; M. anisopliae+A. indica; M. anisopliae+A. indica+B. dalzielii and Decis. Each treatment replicated four times. Vigna unguiculata plants were sprayed from flowering stage thrice with insecticidal products at 5 day intervals. The density of adults and larvae thrips was assessed on 5 flowers per block during 5 days after the last spraying of treatments. Results showed that, there were more thrips on Bafia variety than B125 variety (p<0.0001). All the tested treatment significantly (p<0.0001) reduced the cowpea flower thrips of 30% for A. indica, B. dalzielii and A. indica+B. dalzielii, 75% for M. anisopliae and its various combinations, and of 90% for Decis. Plants extracts, mycoinsecticide and their combinations considerably reduced damage induced by thrips compared to the negative control. A. indica, B. dalzielii, M. anisopliae and their combinations showed ability as natural traitement for the management of thrips in V. unguiculata. These products do not only protect V. unguiculata crop from its major pest, but also preserve the environment from harmful effects induced by the use of synthetic commercial pesticides.

“…The effect of Annona senegalensis and Boswellia dalzielii leaf fractions on Ae. aegypti showed that n-hexane and chloroform fractions of A. senegalensis were more effective than others with CL 50 values of 379.3 and 595.2 mg/L, respectively and 537.1 and 585.5 mg/L for n-hexane and chloroform, respectively for B. dalzielli; the activity was due to the presence of alkaloids, steroids, phenolic compounds, terpenoids, fats and oils in both plants [30]. Thevetia nerviifolia, Plumeria acuifolia and Lantana camara ethanol extracts showed their IGR activity against Ae.…”

“…The most resource in gum of B. dalzielii [26] makes it viscous, favourising its adhesion that could make B. dalzielii treatment to be more effective than A. indica treatment. According to Ibrahim et al [27], the adhesion is an important factor for the effectiveness of a treatment.…”

Cowpea yield improvement is done by adding agricultural inputs. The use of natural substances as pesticides is being encouraged to fight against cowpea field pests. The pesticidal potentials of Azadirachta indica and Boswellia dalzielii water extracts, Metarhizium anisopliae, alone and in combination with plant extracts, and a commercial synthetic pesticide (Decis®) were tested in field on two varieties of cowpeas, Vigna unguiculata in two agroecological zones (Guinean Savanah and Sahelian Savanah) of Cameroon. The field trials were carried out in a full randomized block design including nine treatments and a control. Four replications were made concerning the different treatments and control. At the flowering stage, the cowpea field was sprayed three times with different pesticidal formulations at the interval of five days. The number of ramifications per plant, and that of pods per block and seed yield were determined. The pesticide formulations considerably (p < 0.0001) improved cowpea yield in the two agro-ecological zones. The production parameters were highly influenced by variety and agroecological zone. The extracts and their combinations were as effective as synthetic pesticide (Decis®). Bafia variety treated with the combination of M. anisopliae and A. indica recorded the highest ramification rate (37.03 ± 1.59) in Maroua (Sahelian Savanah). The same variety also produced more important pods number (90.50 ± 16.66) in Ngaoundere (Guinean Savanah) with the binary combination of two plants used in this experiment. The highest seed yield (44.23 ± 2.31
