1. Bioatividade e efeito residual de nanoformulações de nim sobre Spodoptera frugiperda (J.E. Smith) / Bioactivity and residual effect of neem nanoformulations to Spodoptera frugiperda (J.E. Smith)
Neem extracts were nanoformulated with several types of nanoparticles and polymers in a tentative to reduce the biodegradation of neem active compounds and improve their residual effect. These nanoformulations were tested against Spodoptera frugiperda and their efficacy compared to a commercial product. The polymers poly(-caprolactone) (PCL), poly(- hidroxib

2. Ecology of Brevipalpus phoenicis (Geijskes) (Acari: Tenuipalpidae) on coffee plantations in the State of São Paulo / Ecologia do ácaro da mancha-anular (Brevipalpus phoenicis (Geijskes) (Acari: Tenuipalpidae) em cafeeiros no estado de São Paulo
The knowledge on the interactions among Brevipalpus phoenicis (Geijskes), other phytophagous or predaceous mites and coffee plants is still insufficient to establish an adequate management program for this crop, in order to minimize the problems caused by coffee ringspot virus (CoRSV), transmitted by B. phoenicis. In spite of the problem, little is known on

3. Busca de substâncias de Trichilia pallida e Trichilia pallens (Meliaceae) com atividade sobre a traça-do-tomateiro Tuta absoluta (Meyrick) (Lep.: Gelechiidae). / Searching Trichilia pallida and Trichilia pallens (meliaceae)for substances with insecticidal activity against the tomato leafminer Tuta absoluta (Meyrick) (Lep.: Gelechiidae).
Organic and aqueous extracts of the Meliaceae Trichilia pallida and Trichilia pallens were produced for the isolation and identification of substances with insecticidal activity against the tomato leafminer Tuta absoluta. Leaf and twig freeze-dried aqueous extracts (FDA) of both Trichilia species were resuspended in water at a concentration of 3% and sprayed

4. Atividade inseticida e modo de ação de extratos de meliáceas sobre Bemisia tabaci (Genn., 1889) Biótipo B. / Insecticidal activity and action way of extracts from meliaceae plants on silverleaf whitefly Bemisia tabaci (genn., 1889) Biotype B.
Foram conduzidos experimentos com o objetivo de avaliar a bioatividade e o modo de ação de extratos aquosos e orgânicos de ramos de Trichilia pallida Swartz e extratos aquosos de sementes de nim, Azadirachta indica A. Juss, em relação a ninfas e ovos da mosca-branca Bemisia tabaci (Genn.) biótipo B. Inicialmente, verificou-se que o extrato aquoso de se
