First report of damage and population dynamics of Raoiella indica Hirst (Acari: Tenuipalpidae) on Euterpe oleracea (Arecaceae) in the State of Bahia, Brazil

The presence of the red palm mite Raoiella indica Hirst, was recorded on açaí, Euterpe oleracea Mart. (Arecaceae), in Porto Seguro, Bahia State, northeastern Brazil. We evaluated the population dynamics of R. indica from September 2019 to February 2020. The population outbreak and most severe damage caused by R. indica was observed in February, a period of highest temperatures and low relative humidity. This is the first report of damage caused by the red palm mite on E. oleracea in Brazil. Management practices must be implemented to avoid intercropping açaí with other hosts of this mite e.g. coconut, banana and palm trees in order to minimize the occurrence and damage of R. indica on such agrosystems.

Raoiella Indica

The red palm mite, Raoiella indica Hirst, 1924 (Tenuipalpidae), has been spreading rapidly and expanding its host range in the Neotropical region. Most of the hosts are palm trees (Arecaceae). In the present work, high population levels of R. indica are reported on “carnauba” [Copernicia prunifera (Miller) H. E. Moore, Arecaceae] in the states of Alagoas and Ceará, northeastern Brazil. This is the first report of R. indica causing damage and injuries on this palm tree native to Brazil in field. Our results allow us to conclude that carnauba is a suitable host for R. indica, with potential risk to its cultivation and exploitation.

Abstract Due to the increasing national and international demand, the cultivation of açaí palm trees (Euterpe oleracea Mart.) has expanded to upland areas in Brazil. Most of these areas present low natural soil fertility, in which boron (B) is one of the most limiting nutrients. This study aimed to evaluate the productivity of fresh fruits of fertigated açaí trees submitted to doses of B. The study was carried out in Tomé-Açu, northeastern Pará, Brazil. The experimental design consisted of randomized blocks with four treatments: control and addition of 20, 40 and 60 g of B clump-1. After 17 months, bunches of fresh fruits were collected and the production per hectare was estimated. An economic analysis was carried out considering the costs of fertilization and fruit production. The productivities obtained in the treatments were considered above the average of the municipality of Tomé-Açu. The estimated content of leaf B that provided the highest productivity was 14.9 mg kg-1, for a yield of 5479 kg ha-1 year-1¸ while the critical content corresponded to 13.2 mg kg-1. The highest productivity of fresh açaí fruits was achieved with the dose of 20 g of B clump-1, which provided a net gain of 42%.
