Despite the first eradicativeSolanaceae measures taken by the UK in 2008 and Germany in 2011, the pest was found again in Germany (2012), in Slovenia (2012), in Cyprus (2013), in Romania (2013), in Hungary (2014) and in Serbia (2015). Although the import of Aceria kuko intended for planting is prohibited in Europe, the parcels ordered by mail escape the pest and disease control services. Our field observations regarding the attack frequency, attack intensity and the losses indicate that is a potential threat for goji growers.

Hein The wheat curl mite (Aceria tosichella Keifer) (WCM) is a vector of three plant viruses to wheat (Triticum aestivum L.) including: Wheat streak mosaic virus (WSMV), Triticum mosaic virus (TriMV), and High Plains wheat mosaic virus. This wheat-mite- virus complex causes significant yield loss in winter wheat across the Great Plains. Management of WCM host plants during the time between wheat harvest and planting of the new wheat crop (the green bridge) is critical in reducing potential risk and loss from this complex.

LEM causes a type of gall called ‘erineum’ (abnormal felty growth of trichomes from the epidermis), where it feeds, reproduces and protects itself from biotic and abiotic adversities. In February of 2018, LEM was found in a commercial lychee orchard on Pine Island, Florida. Infestations were recorded on young leaves, stems, and inflorescences of approximately 30 young trees (1.5–3.0 yrs.) of three lychee varieties presenting abundant new growth.

Members of the family Rubiaceae were found more susceptible to gall formation, as 6 species showed the presence of mite galls. The maximum number of gall forming eriophyid species could be recovered from the plants growing in Kozhikode district, disclosing 18 species. Lowest number of eriophyid species could be recovered from Palakkad district, showing only 7 species. Keywords: Economically important plants, Eriophyid mites, galls, North Kerala. 1.

  • The Role of the Mite Orthogalumna Terebrantis in the Biological Control Programme for Water Hyacinth, Eichhornia Crassipes, in South Africa
    The role of the mite Orthogalumna terebrantis in the biological control programme for water hyacinth, Eichhornia crassipes, in South Africa A thesis submitted in fulfilment of the requirements for the degree of DOCTOR OF PHILOSOPHY of Rhodes University by DANICA MARLIN December 2010 Abstract Water hyacinth (Eichhornia crassipes) is an aquatic macrophyte originating from the Amazon basin. Due to its beautiful appearance it has been introduced into numerous countries across the world as an ornamental pond plant. It was introduced into South Africa in the early 1900s and has since reached pest proportions in many of the country’s fresh water bodies, causing significant economic and ecological losses. It is now considered to be the worst aquatic weed in South Africa. Efforts to control the spread of the weed began in the early 1970s and there have been some successes. Biological control has been used widely as an alternative to mechanical and chemical controls because it is cost-effective, self-sustaining and environmentally friendly. To date, six biological control agents have been introduced onto water hyacinth in South Africa. However, due to factors such as cold winter temperatures and interference from chemical control, the agent populations are occasionally knocked-down and thus the impact of biological control on the weed population is variable. In addition, many South African water systems are highly eutrophic, and in these systems the plant growth may be accelerated to such an extent that the negative impact of the agents’ herbivory is mitigated. One of the agents established on the weed is the galumnid mite Orthogalumna terebrantis, which originates from Uruguay.
