“…Whiteflies have been reported in several countries associated with coconut palm, but without causing severe damage. However, in Brazil, of a total of 17 species associated with this palm tree (OMENA et al, 2012), A. pseudugesii has been the most aggressive species causing great damage to coconut crops (FERREIRA et al, 2011).…”

Coconut palm (Cocos nucifera L.) is one of the most important tropical species used by man, known as “tree of life”. In recent decades, with the expansion of coconut growing areas, limitations such as the occurrence of pests, uniformity of crops, adaptation to different ecosystems and others have affected the production and longevity of coconut trees. This review describes the major advances in propagation techniques of coconut palm, conventionally, by seeds and through plant tissue culture techniques from the mid-twentieth century onwards, as well as phytosanitary aspects that should be considered to mitigate the spread of pests and diseases.

“…However, outbreaks of A. pseudugesii were recorded in Brazil in 2006 (Bahia state) and in 2007 (Ceará state). In 2011, the pest had already reached all coconut producing areas of the Brazilian national territory (FERREIRA et al, 2011;OMENA et al, 2012).…”

A survey was conducted in the farmers’ orchards of 7 coastal districts, namely Patuakhali, Barguna, Barishal, Khulna, Bhola, Laxmipur, and Noakhali of Bangladesh to know the abundance of rugose spiraling whitefly on coconut and an experiment consisting of 5 treatments and an untreated control following RCBD with 3 replications was also carried out for controlling rugose spiraling whitefly at Patuakhlai Science and Technology University (PSTU) campus during January to May, 2022. Results revealed that the highest abundance (23 egg spirals, 34 nymphs, 31 adults per leaflet, respectively) of rugose spiraling whitefly was found at Khulna, followed by Noakhali (19 egg spirals, 31 nymphs, 27 adults per leaflet, respectively) while the lowest (9 egg spirals, 13 nymphs, 11 adults per leaflet, respectively) was in Patuakhali among 7 coastal districts. Although all insecticidal treatments (T1 = Tyfos 48 EC (Chlorpyrifos) @ 1 ml/L of water, T2= Caught 10 EC (Cypermethrin) @ 1 ml/L of water, T3 = Nitro 505 EC (Chlorpyrifos + Cypermethrin) @ 1 ml/L of water, T4= Fyfanon 57 EC (Malathion) @ 1 ml/L of water, T5= Bioclean @ 1 ml/L of water) effectively reduced the different stages of rugose spiraling whiteflies compared to untreated control, the lowest mean number of egg spirals (0.00), nymphs (0.11) and adults (0.11) per leaflet were obtained by the application of Nitro 505EC @ 1 ml/L of water followed by Bioclean @ 1 ml/L of water at 3 DAS. The highest percent reduction of egg spirals (100%), nymph (98.82%), and adult (98.79%) of whitefly population over control were also obtained by the application of Nitro 505EC @ 1 ml/L of water followed by Bioclean @ 1 ml/l of water at 3 DAS. These two chemicals were found to be very effective for controlling rugose spiraling whiteflies. Considering environmental safety, Bioclean @ 1 ml/L of water is recommended to use against this pest as an eco-friendly approach for safe food production. J. Asiat. Soc.

“…The whitefly Aleurodicus pseudugesii Martin, 2008 (Hemiptera: Aleyrodidae) was first identified from specimens found on coconut trees in Ecuador and Peru (Martin 2008). In Brazil, it has been reported damaging coconut trees (Cocos nucifera L. -Arecaceae) in states in the Northeast (Alagoas, Bahia, Ceará, Paraíba, and Sergipe), North (in the northern region of Pará), and Southeast (in the southeastern region of Rio de Janeiro) (Ferreira et al 2011;Omena et al 2012).…”
