“…However, the use of insecticide, drawing upon a limited set of products, has proven not to be a sustainable management option for this pest in South America. Since the 1980s, efficacy of organophosphates for T. absoluta control has gradually decreased in countries like Bolivia, Brazil and Chile (Salazar and Araya 1997;Siqueira et al 2000Siqueira et al , 2001. In addition, resistance development has been reported against organophosphates and pyrethroids in Chile (Salazar and Araya 1997) and against abamectin, cartap, methamidophos and permethrin in Brazil (Siqueira et al 2000(Siqueira et al , 2001.…”

Biological invasion of European tomato crops by Tuta absoluta: ecology, geographic expansion and prospects for biological control

The tomato leafminer Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is a devastating pest of tomato originating from South America. After its initial detection in eastern Spain in 2006, it rapidly invaded various other European countries and spread throughout the Mediterranean basin. If no control measures are taken, then the pest can cause up to 80-100% yield losses in tomato crops in recently invaded areas and may pose a threat to both greenhouse and open-field tomato production. The exceptional speed and extent of T. absoluta invasion have called for studies documenting its biology and ecology, while indicating an urgent need for efficient and sustainable management methods. The development of approaches to manage T. absoluta would be facilitated through a detailed revision of information on this pest in its area of origin. This review combines information on the invasion by T. absoluta, its ecology, and potential management strategies, including data that may help the implementation of efficient biological control programs. These programs, together with a variety of other management tactics, may allow efficient integrated pest management of T. absoluta in Europe and Mediterranean Basin countries.

“…In abamectin-resistant strains of the spider mite Tetranychus urticae and the sweet-potato whitefly Bemisia tabaci GST activity against CDNB was increased (Stumpf and Nauen 2002;Wang and Wu 2007). On the contrary, total GST was not changed in Brazilian populations of the tomato leaf-miner Tuta absoluta (Siqueira et al 2001). In this study, GST activity in the isopods decreased at the highest abamectin concentrations tested (100 and 300 mg/kg dry soil) and also in starved animals.…”

To determine effects of the antiparasitic veterinary drug abamectin on the isopod Porcellio scaber, animals were exposed for 21 days to Lufa 2.2 soil spiked at concentrations of 3-300 mg/kg dry soil. After exposure, abamectin residues in the isopods were analysed using a novel analytical method. Toxicity was evaluated on different levels of biological organisation: biochemical, cellular and the individual organism. Measurements included glutathione S-transferase (GST) activity and stability of cell membranes in the digestive gland, animal mass gain or loss, food consumption, behaviour and mortality. LC50 for the effect of abamectin on survival of P. scaber was 71 mg/kg dry soil. The most obvious sublethal effects were reduced food consumption and decreased body mass (NOEC 3 mg/kg dry soil). Additionally, loss of digging activity and reduced GST activity (NOEC 30 mg/kg dry soil) and cell membrane destabilization (NOEC 10 mg/kg dry soil) were recorded. Abamectin only slightly accumulated in the isopods, with bioaccumulation factors always being \0.1. Based on these results and current information on environmental levels of abamectin, it is not likely that isopods will be affected by abamectin, but further studies with exposure through faeces are recommended.

“…The intensive chemical applications also create residual problems and a possibility of pest resistance development together with environmental pollution . The pest has resistance to abamectin, cartap, methamidophos, permethrin and deltamethrin has been known (Siqueira et al, 2000(Siqueira et al, , 2001Lietti et al, 2005). Moreover, the methods that can be applied against the pest within the scope of integrated pest management such as biological control cannot be used because of the intensive chemical applications.…”
