Abstract

From April to August 2018, seasonal variation of the populations and the damage due to Aphis gossypii (Aphididae) and Bemisia tabaci (Aleyrodidae), two sap-sucking pests on Pepper (Capsicum annuum L.), was carried out in a forestry region of Cameroon with bimodal rainfall. This study focused on 133 days after transplanting (DAT). Populations were counted by 5 leaves per plant during 19 weeks, 02 seasons and 03 phenological phases of plant. Average number of individuals and attacked leaves due to these pests were correlated with total rainfall, mean temperature and mean relative humidity. The study showed that the average number of A. gossypii and B. tabaci per 5 leaves per plant varied significantly with sampling weeks (df=18, F=8.50, p<0.001 and df=18, F=4.87, p<0.001 respectively), seasons (df=1, F=2.99, p<0.01 and df=1, F=12.58, p<0.001 respectively) and with phenological phases of C. annuum (df=2, F=111.07, p<0.01 and df=2, F=132.74, p<0.01 respectively). The highest population were recorded at the 13th sampling week corresponding to 91 days after transplanting (91 DAT) with 5.30±0.8 individuals/5 leaves for A. gossypii and 2.30±0.42 individuals/5 leaves for B. tabaci. Average number of A. gossypii and B. tabaci were highest in the short dry season with 3.49±0.17 individuals/5 leaves and 0.83±0.07 individuals/5 leaves respectively. The study also showed that damage due to A. gossypii / B. tabaci complex varied significantly with sampling weeks (df=18, F=3.02, p<0.004), with seasons (df=1, F=9.69, p<0.001) and with phenological phases of C. annuum (df=2, F=20.31, p<0.005). These damage were higher in the first sampling week corresponding to 7 days after transplanting (7 DAT) with an average attack rate of 31.25±5.56%, during the short rainy season with an average attack rate of 20.57±1.48% and during the pre-flowering phase with an average attack rate of 20.85±1.10%. Average number of A. gossypii and B. tabaci individuals showed negative and non-significant correlations with total rainfall (r=-0.80, p<0.104 and r=-0.60, p<0.284 respectively) and mean temperature (r=-0.86, p<0.057 and r=-0.29, p<0.637 respectively), then positive and significant for A. gossypii (r=0.89, p<0.040) and positive and non-significant for B. tabaci (r=0.11, p<0.857) with relative humidity. Damage due to hemipteran complex showed positive and non-significant correlations with total rainfall (r=0.60, p<0.285) and mean temperatures (r=0.87, p<0.058) and negative and significant correlations with relative humidity (r=-0.86, p<0.041). The present study provided baseline data for integrated pest management strategies against A. gossypii and B. tabaci on C. annuum in forestry region of Southern Cameroon.
