Recommendations A. The technical advisors recommend the FSC Pesticides Com mittee to approve a derogation to use the following insecticides for control of leaf-cutting ants (Atta and Acromyrmex species) in nurseries and forest plantations in Brazil: deltamethrin (dust formulation K-Othrine), fenitrothion, fipronil, and sulfluramid, provided that during the derogation period the certificate holder s: 1. identify which species of leaf-cutting ant causes most damage, estimate level of damage, define a critical nest density (maximum acceptable density for achieving silvicultural objectives), 2 monitor distribution of ant nests, and locate infested areas with a critical density of nests; 2. reduce the amount of deltamethrin, fenitrothion, fipronil, and sulfluramid used to the minimum needed for effective control, limit use to highly infested areas (where estimated nest density exceeds critical density) or nurseries or young plantations during establishment (in the first 1-3 years), and complement these with alternatives, e.g. spinosad, borax, rotenone, pathogenic fungi combined with diatomatomaceous earth and extracts of Manihot esculenta, Ateleia glazioviana / ® Citromax , etc; 2 Zanetti R.

The technical advisors recommend the FSC Pesticides Committee to reject the application for a derogation for alpha-cypermethrin to control yellow beetles (Costalimaita ferruginea) or other lepidopteran or coleopteran defoliating insects forest plantations in Brazil, as the evidence provided of a need for alpha-cypermethrin did not demonstrate that this is the only feasible way of controlling the targeted pest insects and that these species are causing severe damage (e.g. based on field tests with alternative non-chemical or less toxic methods of pest management, cost-benefit analysis, social and environmental impact assessment, as required by FSC (2007) Procedure: Processing pesticide derogation applications), and also as more selective alternatives are available. C. The technical advisors recommend the certificate holders who applied for a derogation for alpha- cypermethrin to: 1. monitor distribution of Costalimaita ferruginea or other coleopteran defoliators, locate infested areas with a high density of Costalimaita or other defoliators, identify the type of defoliating insect (genus and, if possible, species), estimate damage level, and define a critical density of Costalimaita or of other defoliators (maximum acceptable density for achieving silvicultural objectives); 3. retain old tree stumps and plant seedlings between stumps to provide „trap stumps‟ (with sprouts distracting Costalimaita from seedlings), assess the potential of inter-planting trap plants to distract beetles (preferred plants or robust eucalyptus species), promote natural enemies (e.g. parasitic wasps Trichogramma, Anaphes nitens) by preserving fragments of native vegetation in/around Eucalyptus plantations or reducing weed control to the minimum (retaining weeds partially between tree rows), limit control of Costalimaita and of other coleopteran defoliators to the most highly infested areas (where estimated density of Costalimaita or defoliators exceeds critical density) and areas with susceptible tree species, and if necessary use a low-toxicity insecticide (spinosad or azadirachtin); 3. conduct field tests on control of coleopteran defoliators with Bacillus thuringiensis (B.t. subsp. tenebrionis or B.t. subsp. kurstaki), pathogenic fungi (Metarhizium anisopliae, Trichoderma species, Beauveria bassiana combined with B.t., etc), viruses (granuloviruses or nucleopoly- hedroviruses (NPVs) specific to coleopteran insects), use of natural enemies (predatory or parasitic insects) and explore the possibility of using spinosad or azadirachtin (neem extract) for control of Costalimaita or other coleopteran defoliators (e.g. in tests based on temporary special registration RET); D. The technical advisors recommend the FSC Pesticides Committee to reject the application for a derogation for deltamethrin (liquid formulation Decis 25 CE) to control Eucalyptus brown looper (Thyrinteina arnobia) or other lepidopteran or coleopteran insects in forest plantations in Brazil, as evidence provided of a need for deltamethrin did not demonstrate that this is the only feasible way of controlling the targeted pest insects and that these species are causing severe damage (e.g. based on tests with alternative non-chemical or less toxic methods of pest management, cost-benefit analysis, social and environmental impact assessment, as required by FSC (2007) Procedure: Processing pesticide derogation applications), and also as more selective alternatives are available. March 2010 8 Insecticides for Control of Pest Insects in FSC Certified Forests in Brazil – Recommendations by Technical Advisors E. The technical advisors recommend the certificate holders who applied for a derogation for deltame- ® thrin (liquid formulation Decis 25 CE) to: 1. monitor the distribution of Thyrinteina arnobia or other defoliating insects, locate infested areas with a high density of Thyrinteina or defoliators, identify the type of defoliating insect (genus and, if possible, species), estimate level of damage, and define a critical density of Thyrinteina or 6 other defoliating insects (maximum acceptable density for achieving silvicultural objectives); 2. promote the establishment of natural enemies (such as Trichogramma wasps and parasitic wasp Anaphes nitens) by preserving fragments of native vegetation surrounding Eucalyptus plantations, limit control of Thyrinteina and defoliators to highly infested areas (where estimated density of Thyrinteina or of defoliators exceeds the critical density) and areas with susceptible tree species, and if necessary use Bacillus thuringiensis (B.t. subspecies kurstaki or B.t. subspecies aizawai) or B. t. combined with a selective, low-toxicity insecticide (such as spinosad, 7 azadirachtin, or neem); 4. conduct field tests on alternatives, in particular Bacillus thuringiensis (B.t. subspecies kurstaki, B.t. subsp. aizawai), pathogenic fungi (Beauveria bassiana, Metarhizium anisopliae, Trichoderma species, or combinations with B.t.), viruses (granulovirus or nucleopolyhedrovirus (NPV) specific to lepidopteran insects), mass-rearing and release or preservation of natural enemies (predatory insects such as Podisus nigrispinus or Supputius cincticeps), and explore the possibility of using spinosad or azadirachtin for control of Thyrinteina (e.g. in tests based on a temporary special registration); F. The technical advisors recommend the FSC Pesticides Committee to approve a derogation to use ® fipronil (dispersible granules Tuit Florestal) for treating the roots of seedlings preventively against termites (Cornitermes bequaerti and Syntermes molestus) prior to planting in forest plantations in Brazil, provided that during the derogation period the certificate holders: 1. identify which termite species is present locally, monitor damage level and presence of termites 8 in nurseries or young forests, and locate areas where C. bequaerti or S. molestus are prevalent; 2. reduce the amount of fipronil used to the necessary minimum, limit seedling treatment to areas where C. bequaerti or S. molestus is present and to areas with seedlings of susceptible tree species, and consider reduced tillage or no-till (e.g. combined with a cover crop such as Mucuna bracteata); 3. if termite colonies are targeted directly (e.g. termites attacking buildings), use biological agents, in particular pathogenic fungi Metarhizium anisopliae (e.g. M. anisopliae strain ESF1 or M. 6 Pereira L.G.P.
