“…The most crucial aspect of mite attack has been attributed to the loss in copra weight, estimated to almost reach 32% (Haq and Sobha, 2010). The present findings are in conformity with (Muralidharan et al, 2001) who reported 30.94% and 41.74% losses in terms of copra and husk, respectively in Alappuzha district of Kerala.…”

“…Button/nut invasion by the coconut mite and the consequent deleterious effects favouring nut fall, husk damage and reduction in nut size leading to yield loss have been studied by different authors (Doreste, 1968;Mariau, 1977;Moore et al, 1989;Nair et al, 2002;Rethinam, 2003;Haq, 2007;Haq & Sumangala, 2001;Haq & Sobha, 2010).…”

“…The most crucial aspect of mite attack has been attributed to the loss in copra weight, estimated to almost reach 32% (Haq & Sobha, 2010); however, the impact on oil production has not been assessed. In addition, losses due to husk damage has been estimated at 41.74% (Muralidharan et al, 2001), particularly because of the reduction of fiber length by 26-53% and the consequent extra cost for de-husking (Muralidharan et al, 2001;Beevi et al, 2003).…”

Coconut destiny after the invasion of Aceria guerreronis (Acari: Eriophyidae) in India*

The coconut mite, Aceria guerreronis Keifer, has emerged as a common menace to most of the coconut plantations in India. After its first upsurge in Kerala at the end of the 1990´s, the mite has spread to many states in southern and northern India, causing considerable damage. Coconut provides one third of the agricultural income in the regions in which it is grown and more than 10 million people are dependent on this cash crop directly or indirectly through coconut-based industries like coir, copra, oil, honey, furniture, handicrafts, beverages, bakery products and so on. The economic instability of the coconut farming community and the people employed in coconut-based industries rank the highest order. A critical assessment of the various problems created by A. guerreronis in the agricultural economy of India is presented in order to supplement data on crop loss through nut malformation, nut fall, loss in fibre and copra. Varietal differences in susceptibility of the plant and future strategies in terms of management practices for an early control of the mite are discussed, and suggestions for future activities to alleviate mite damage are presented.

Coconut (Cocos nucifera L.) is an important crop in West Bengal, India. The coconut mite, Aceria guerreronis Keifer (Eriophyidae), is becoming a serious threat to its cultivation in that state. This mite lives underneath the perianth, attacking the epidermis and causing damage that leads to considerable yield reduction. The same habitat was found to be shared by several other mites during a one year study in a coconut orchard in South 24 Parganas District ofWest Bengal, in 2007–2008. In total, 11 species of nine families were found in this study, including mites of different feeding habits, but mainly predatory and phytophagous mites. Neoseiulus paspalivorus (De Leon) was the predominant predator, while A. guerreronis was the predominant phytophagous species. Both were found throughout the year. The highest abundance of those species occurred in April and June, respectively. The association of N. paspalivorus and A. guerreronis has been observed in different countries and in other parts of India.
