“…Based on phylogenetic analysis, the identified P. bondari isolate was closely related to P. bondari and P. minei isolates but distantly related to A. dispersus whitefly species based on the clustering on the phylogeny tree. This is in agreement with previous reports, confirming the identity of the isolates detected in this study [ 32 , 64 , 65 ]. This is the first report of Bondar’s nesting whitefly species, Paraleyrodes bondari (Hemiptera Aleyrodidae) colonizing cassava in Kenya, specifically in the coastal region of Kenya.…”

“…For example, coconut and guava hosts may sustain reproduction and development of P. bondari whitefly species, with adults migrating/dispersing to cassava and therefore the P. bondari whitefly occurring on cassava were present as visitors and were not colonizing the crop. However, recent reports on occurrence and distribution of P. bondari on cassava in Uganda by Omongo et al [ 32 ] and Isabirye [ 67 ] indicates a possibility of adaptability of the whitefly species on cassava crop. Being an invasive whitefly species, further extensive surveillance to map the species distribution and possibly elucidate the possible origin, host range and the possible role in transmission of cassava viruses or viruses infecting other crops in Kenya.…”

“…Khamisi et al [ 31 ] identified B. afer and A. dispersus on cassava in Kenya, although their role in transmission of viruses infecting the crop has not been elucidated. In addition, a recent report of P. bondari on cassava in Uganda by Omongo et al [ 32 ] indicates the need to understand its potential role in transmission of cassava viruses.…”

“…The use of mitochondrial DNA cytochrome oxidase I gene (mtCO1), first reported by Frohlich et al [ 42 ] has been the most widely used molecular approach to distinguish different whitefly species that can be associated with specific biotypes. The region provides the highest genetic variability among the whitefly species and has been widely used in identification of the B. tabaci complex groups [ 8 , 11 , 12 , 32 , 33 , 41 , 43 , 44 ]. Use of mtCO1 gene allows B. tabaci sequence data to be applied to more global phylogenetic questions with a large number of mtCO1 Bemisia species sequences currently available in the Genbank [ 44 ].…”

The whitefly, Bemisia tabaci (Gennadium, Hemiptera) has been reported to transmit viruses that cause cassava mosaic disease (CMD) and cassava brown streak disease (CBSD) in many parts of sub-Saharan Africa (SSA). Currently, there is limited information on the distribution, species and haplotype composition of the whitefly populations colonizing cassava in Kenya. A study was conducted in the major cassava growing regions of Kenya to address this gap. Analyses of mitochondrial DNA cytochrome oxidase 1 (mtCO1) sequences revealed the presence of four distinct whitefly species: Bemisia tabaci, Bemisia afer, Aleurodicus dispersus and Paraleyrodes bondari in Kenya. The B. tabaci haplotypes were further resolved into SSA1, SSA2 and Indian Ocean (IO) putative species. The SSA1 population had three haplogroups of SSA1-SG1, SSA-SG2 and SSA1-SG3. Application of KASP genotyping grouped the Bemisia tabaci into two haplogroups namely sub-Saharan Africa East and Southern Africa (SSA-ESA) and sub-Saharan Africa East and Central Africa (SSA-ECA). The study presents the first report of P. bondari (Bondar’s nesting whitefly) on cassava in Kenya. Bemisia tabaci was widely distributed in all the major cassava growing regions in Kenya. The increased detection of different whitefly species on cassava and genetically diverse B. tabaci mitotypes indicates a significant influence on the dynamics of cassava virus epidemics in the field. The study highlights the need for continuous monitoring of invasive whitefly species population on cassava for timely application of management practices to reduce the impact of cassava viral diseases and prevent potential yield losses.

“…The green peach (peach-potato) aphid and Myzuspersicae (Sulzer) are the most destructive pests of potatoes, while whiteflies (Homoptera: Aleyrodidae) are severe pests of several crops, including potato, okra and cotton [29,30], and many vegetables, i.e. bitter gourd, okra and potato, which can be severely damaged by whiteflies, and they can also cause a significant loss to potato crop production [31][32][33].…”

In the present study, six potato varieties (Evora, Hannat white, Lacetta, Mustang, SH-5, Anats) were evaluated for phenotypic diversity and pest management based on various qualitative and quantitative traits. Data on various morphological traits and insect/pest infestation frequencies were compile for three plants of each variety. Statistical investigation of data showed significant variations in different morphological characteristics such as plant height, leaf length, leaf width, tuber diameter, and tuber yield, and insects/frequencies (aphids, leafhopper, thrips and whiteflies). Our results showed that despite the maximum infestation frequency for aphids (20.80 insect/plot), leafhopper (24.22 insect/plot), thrips (11.09 insect/plot) and whiteflies (15.73), significantly higher plant height (22.65 cm), leaf length (6.20 cm), leaf width (4.66 cm), tuber diameter (3.43 cm), and tuber yield (12.80 kg), of Lacetta (v.no3) revealed, indicating that this variety is highly resistant/tolerant to these insects/pests. While SH-5 was second to it as regards insect infestation rate and yield, potato varieties Hannat white showed minimum plant height (18.18 cm), leaf length (4.09 cm), leaf width (3.41 cm), tuber diameter (2.41 cm), and tuber yield (7.55 kg), with lowest infestation frequencies for aphids (14.43 insects per plot), leafhopper (17.72 insects/plot), thrips (7.22 insects/plot), and whiteflies (12.97 insects/plot), indicating that this variety is more susceptible to various insects. Based on these results, the varieties Lacetta and SH-5 should be recommended for the cultivation of agro-climatic conditions of Mansehra in order to get maximum yield and to protect the environment and human health from the adverse effects of insecticides and pesticides.
