1. Screening of plant extracts and fractions on Aedes aegypti larvae found in the state of Mato Grosso do Sul (linnaeus, 1762) (culicidae)
ABSTRACT The constant use of chemical insecticides for Aedes aegypti control has caused resistance in the mosquito populations. Thus, the objective of this study was to analyze the larvicidal potential of extracts and fractions of plants on A. aegypti larvae. The analysis included sixty one extracts and twenty five fractions of fifty botanical species at con

2. In vitro evaluation of the effect of botanical formulations used in the control of Aedes aegypti L. (Diptera: Culicidae) on liver enzymes.
Abstract: INTRODUCTION: Dengue fever is a viral disease transmitted by the Aedes aegypti Linn. (1792) (Diptera: Culicidae) mosquito, which is endemic in several regions of Brazil. Alternative methods for the control of the vector include botanical insecticides, which offer advantages such as lower environmental contamination levels and less likelihood of re

3. Simaroubaceae family: botany, chemical composition and biological activities
The Simaroubaceae family includes 32 genera and more than 170 species of trees and brushes of pantropical distribution. The main distribution hot spots are located at tropical areas of America, extending to Africa, Madagascar and regions of Australia bathed by the Pacific. This family is characterized by the presence of quassinoids, secondary metabolites res

4. O extrato de neem (Azadirachta indica) causa alterações no desenvolvimento ninfal, no aparelho reprodutor e sistema digestivo do predador Supputius cincticeps (Heteroptera: Pentatomidae)? / Does the neem (Azadirachta indica) extract cause nymphal development, the reproductive system and digestive tract of the predator Supputius cincticeps (Heteroptera: Pentatomidae)?
The subfamily Asopinae presents important species of predators, as Supputius cincticeps (Stal) (Hemiptera: Pentatomidae). These stinkbug present potential for the biological control of Lepidoptera defoliators in eucalyptus plantations in Brazil.Botanical insecticides, mainly neem (Azadirachta indica), are alternative for the control of herbivore insects of a

5. Acute toxicological effects of extracts of Melia azedarach (Meliaceae) in rats (Rattus norvegicus), mice (Mus musculus) and Artemia salina / Efeitos toxicológicos agudos de extratos de Melia azedarach (MELIACEAE) em ratos (Rattus novergicus), camundongos (Mus musculus) e Artemia salina
The revival of research involving botanical insecticides owes itself to the need to make available new products devoid of environmental degradation, with lesser residual affects and development of resistant insects to synthetic products. Phytochemicals from the family Meliaceae have been considered preeminent pesticides. Among the Maliaceae, one of the plant

6. Impact of botanical insecticide on Apis mellifera, Nannotrigona testaceicornis and Tetragonisca angustula (Hymenoptera: Apidae) / Impacto de inseticidas botânicos sobre Apis mellifera, Nannotrigona testaceicornis e Tetragonisca angustula (Hymenoptera: Apidae)
Adverse effects of organo-synthetic products have motivated search in alternative control of pests. Among this alternative, botanical insecticides present a viable option for the management of these organisms. However, before the choice of the botanical insecticide, some criteria must be analyzed, such as: efficiency to control the pest and selectivity to be

7. Purificação e caracterização parcial de ATPase de larvas de Zabrotes subfasciatus (Coleóptera: Chrysomelidae: Bruchinae) e modulação fitoterápica de sua atividade
Zabrotes subfasciatus is the most common pest of the stored beans (Phaselous vulgaris). This study was carried out to characterize ATPase from Z. subfasciatus larvae and to investigate its phytotherapy modulation. Larvae extracted from Phaseolus vulgaris were firstly homogenised in extraction buffer, and then centrifuged 45000g for 30min at 4C. Supernatant w

10. Evaluation of activity of synthetic chemical acaricides, botanical extract on Rhipicephalus sanguineus and action of essential oils on Amblyomma cajennense. / Avaliação da atividade de acaricidas químicos sintéticos, extrato botânico sobre Rhipicephalus sanguineus e ação dos óleos essenciais sobre Amblyomma cajennens.
Amblyomma cajennense (Fabricius, 1787) (Acari, Ixodidae) known as tick-star, is a ixodid heteroxenous tree-host found too often in horses. Have little specific parasite, particularly in periods of larvae and nymph, is considered the most important in ixodid transmission of spotted fever to humans in Brazil.

12. Insecticide and fungicide activity of the ethanolic extracts of Pachira aquatica in Aubl Hypothenemus hampei (Ferrari) and Fusarium sp / ATIVIDADE INSETICIDA E FUNGICIDA DO EXTRATO ETANÓLICO DE Pachira aquatica AUBL SOBRE Hypothenemus hampei (FERRARI) E Fusarium sp
The coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Scolytidae), is considered as one of the principals plagues of the coffee tree, attacking the fruits all maturation phases. It possesses a short biological cycle and has a great capacity of proliferation, thus causing a phytossanitary problem in all the producing regions of coffee. Initial ef
