“…Pineapple mealybug wilt (PMW) disease is present in pineapple cultivations throughout the world (Hutahayan, 2017;Nyarko and Asare-Bediako, 2019;Massé et al, 2021). The disease has an intriguing etiology and involves a unique relationship between viruses, mealybugs, and ants (Jahn et al, 2003;Dey et al, 2018).…”

“…The PMWaV-2 has a more complex RNA genome compared to PMWaV-1 and both viruses are commonly reported as the main strains to cause the disease (Sether and Hu, 2001;Alvarez et al, 2015). However, recently there are many reports on PMWaV-3 as the strain that has been confirmed to cause PMW in some pineapple cultivation areas (Hernández et al, 2010;Nyarko and Asare-Bediako, 2019;Massé et al, 2021). All virus strains can be transmitted to pineapple plants by insect pests Dysmioccus brevipes and Dysmioccus neobrevipes.…”

Pineapple is a perennial fruit-bearing tropical plant that belongs to the Bromeliaceae family, which has more than 2500 species. Pineapple is known excellent source of minerals and vitamins. It produces substantial calcium, potassium, glucose, the proteindigesting enzyme bromelain, fibre, vitamin A, B and C. In Malaysia, twelve registered varieties of pineapple have been introduced and commercially planted such as Moris (AC1), Sarawak (AC2), Gandul (AC3), Maspine (AC4), Josapine (AC5) Yankee (AC6) Moris Gajah (AC7), N36 (AC8), MD2 (AC9), View of Sunset (AC10), Madu Kaca (AC11), and Keningau Diamond (AC12). The disease is one of the important factors that can contribute to the huge losses of pineapple yield worldwide. This review paper aimed to discuss the main diseases of pineapple and their control management, particularly in Malaysia. The common diseases of pineapple that cause significant yield losses in the farms such as mealybug wilt-associated virus, bacterial heart rot, fruit collapse, butt rot, fruitlet core rot, black rot, yeasty and fusariosis are highlighted and discussed in detail on the causal pathogens, disease symptoms and signs, disease infection and development. The available control measures for managing pineapple diseases were also included in this paper.

“…The development of diagnostic techniques for each virus species has made possible the validation of the presence of PMWaVs in plant material as well as their transmission by an insect vector (Sether et al 1998(Sether et al , 2005Sether and Hu 2002b;Gambley et al 2008). Different studies have confirmed that the three currently classified PMWaV species by the International Committee on Taxonomy of Viruses (ICTV) PMWaV1, PMWaV2, and PMWaV3 are widely distributed in different pineapple production areas around the world (Sether et al 2005;Gambley et al 2008;Asare-Bediako et al 2020;Hernandez-Rodriguez et al 2014;Ochoa-Martinez et al 2016;Massé et al 2021). However, a clear association between PMWaV2 and PMW in the presence of mealybug feeding has only been reported in Hawaii Hu 2002a).…”

MD2 pineapple production in the Valle del Cauca Department, Colombia, has increased in recent years due to its preference in the national and international markets. Pineapple mealybug wilt (PMW), reported in all production areas around the world, is associated with two mealybug species, Dysmicoccus brevipes and D. neobrevipes, and a group of virus species known as pineapple mealybug wilt-associated viruses (PMWaVs). In a previous study, D. brevipes was determined to be the main mealybug species associated with pineapples in the region; hence, the objective of this study was to determine the occurrence and distribution of PMWaVs in pineapple plants and specimens of D. brevipes collected in five MD2 pineapple fields in the Department of Valle del Cauca. Our results confirmed the presence of three virus species in both plant and mealybug specimens. PMWaV3 showed the highest detection frequencies (92.6% and 88.7%), followed by PMWaV1 (26.5% and 8.3%) and PMWaV2 (12.0% and 2.0%) in plant and mealybug samples, respectively. Mixed infections of PMWaVs were found also in the studied plant material. The most common virus association consisting of PMWaV1 and PMWaV3 was found in 30 plant samples (20%). The correlation analysis between each virus species found in mealybugs and their pineapple host suggests that PMWaV3 is not only transmitted through infested plant material, but that D. brevipes may also play a role in the dynamics of disease dissemination. The results of this study contribute to the understanding of PMWaV transmission in MD2 pineapple-cultivated areas in the Valle del Cauca region.
