“…Vieira Júnior et al, (2015) avaliando a entomofauna presente na cultura do Physalis angulata e peruviana perceberam que insetos da ordem hemíptera são as mais recorrentes pragas destas culturas. Já os insetos da ordem díptera correspondendo a 45,61 % (Figura 2 B) dos indivíduos no ecossistema convencional e com ocorrência significativa no sistema ecológico podem ser classificados tanto como pragas agrícolas, urbanas e predadores (KRINSKI et al, 2014).…”

RESUMOOs insetos são a classe mais abundante do planeta, um grupo extremamente diversificado e adaptado a diferentes condições ambientais. O levantamento da entomofauna pode fornecer diagnósticos eficientes quanto à qualidade ambiental, dentre os métodos de amostragens de artrópodes destaca-se a armadilha do tipo Moerick, bastante utilizada para levantamentos, método fácil e econômico, armadilhas deste tipo coletam insetos que são atraídos pela cor e ficam presos ao meio aquoso. O objetivo deste trabalho foi realizar um levantamento da entomofauna em área agrícola de manejo agroecológico e convencional, utilizando bandejas d'água de cor amarela. Em cada área foram instaladas seis bandejas com água, com pelo menos cinco metros de distância, de forma aleatória sobre o solo, contendo 500 mL de água e cinco gotas de detergente neutro. A coleta foi feita mensalmente, as armadilhas permaneciam na área por um período de 24 horas, os insetos eram coletados, e as bandejas remanejadas para a outra área. A área agroecológica apresentou menor número de insetos, porém maior diversidade, diferindo da convencional que apresentou maior número de insetos e menor diversidade, a ordem hymenoptera foi a mais abundante na área agroecológica e a díptera na área convencional. A população de insetos foi maior no mês de março, reduzindo de forma gradativa até o final do estudo. A bandeja de cor amarela é eficiente na captura de insetos, principalmente hymenoptera e díptera.

“…It was shown that the chemical compounds present in these Piperaceae can be further evaluated among the isolation of active molecules to develop new botanical formulations, especially when we consider that the majority of these substances has been reported as potential insecticides in many other studies conducted worldwide (Santos et al, 2010;2013;Cáceres & Kato, 2014, Brito, Baldin, Silva, Ribeiro, & Vendramim, 2015Krinski & Foerster, 2016, Sanini et al 2017, Turchen, Hunhoff, Paulo,Souza, Pereira, 2016b and other plant families (Isman, 2000;Koul, Walia, & Dhaliwal, 2008;Tripathi, Upadhyay, Bhuiyan, & Bhattacharya, 2009;Coitinho, Oliveira, Gondim-Júnior, & Câmara, 2010;Ntalli & Menkissoglu-Spiroudi, 2011, Zoubiri & Baaliouamer, 2011Baskar, Muthu, Raj, Kingsley, & Ignacimuthu, 2012;Krishnappa & Elumalai, 2012;Cáceres & Kato, 2014Krinski, Massaroli, & Machado, 2014;Backiyaraj et al, 2015;Massaroli, Pereira, & Foerster;Costa, Santana, Oliveira, & Serrão, 2017).…”

ABSTRACT. The toxicities of essential oils (EOs) from 18 species of Brazilian Piperaceae were assessed on eggs of the velvetbean caterpillar, Anticarsia gemmatalis. Oils were extracted using steam distillation, and dilutions were made for bioassays at concentrations of 0.25, 0.5, 1.0, 2.0, and 4.0%. All EOs reduced larval hatching. The lowest lethal concentrations were obtained from Piper fuligineum (SP), Piper mollicomum "chemotype 1" (SP), Piper mosenii (PR), Piper aduncum (PA) and Piper marginatum (PA). Ovicidal activity is related to the potential toxicity of several compounds, especially dilapiolle, myristicin, asaricine, spathulenol and piperitone. According to our results, EOs from 16 Brazilian Piper species have potential for use as biorational botanical insecticides.

“…The use of natural insecticides has some advantages over traditional synthetic products, since natural products are potentially less toxic to the environment. Environmental friendly compounds are less concentrated, have faster degradation and are specific to certain insect groups, resulting in less occupational exposure and less environmental pollution [22].…”

How long is long enough? Decreasing on plant extract lethal effects, over time, affectingAedes aegyptilarval mortality

26The mosquito Aedes aegypti has overcome all kinds of human being mosquito control attempts 27 over the last century. Strategies for vector population control resorts to the use of synthetic 28 insecticides, which can lead to problems of intoxication in humans and environmental 29 contamination. We evaluated the effects of Bacillus thuringiensis var. israelensis (Bti), Ilex 30 paraguariensis (mate-herb) and Ilex theezans (caúna-herb) extracts against A. aegypti larvae 31 mortality. The bioassays were conducted under controlled laboratory conditions of temperature 32 (27±3°C) and photoperiod (12h). Hydroalcoholic I. theezans leaves extract displayed better 33 residual effect compared to I. paraguariensis fruit aqueous extract. Variation in larval mortality 34 was also observed in the exposure periods (low after a few weeks). Low mortality after a few 35 weeks may mean increased the food for mosquito in a oppose effect over time. The residual effect 36 of Bti was observed during the 56 days of the study duration (100% of mortality). The strongest 37 residual effect of I. theezans was probably due to the presence of chemical on its leaves, such 38 coumarins, hemolytic saponins and cyanogenic glucosides, absent in I. paraguariensis. On the 39 other hand, alternative methods to vector control present risks in a long term scale by reversal of 40 larvicide effect into food resource. Our results contributed to the prospection of natural insecticides 41 and open the possibility for subsequent studies of the use of plant extracts in field situations in a 42 short time scale.43 44 Keywords: Dengue, vector control, inseticide, entomology, yerba mate. 3 3 45 Introduction 46 Over the last century the mosquito Aedes aegypti Linnaeus, 1762 has overcome all 47 mosquito control attempts by human being. Aedes females are well known by their capacity of 48 naturally and/or under laboratory conditions replicate and transmit over 100 kinds of viruses [1]. 49 As an example, in Brazil dengue, chikungunya, zika and most recently mayaro [1] viruses are a 50 real threat to public health [2]. It became necessary the A. aegypti population control in order to 51 reduce viruses' transmission and consequently the epidemic status. Although several chemical and 52 natural products have being extensively used on attempts to reduce adults and immature mosquito 53 population [3,4], appropriated mosquito population reduction is not close to come true. Especially 54 because the gene resistance selectivity due to chemicals and natural products application misuse 55[5]. Accordingly, the most effective disease prevention method still remains targeting the mosquito 56 population by elimination of mosquito breeding places [6]. 57A very promising field for mosquito population reduction is focusing the mosquito control 58 strategies on the immature aquatic stages, when the insect is more vulnerable [7,8]. For this 59 purpose, the use of synthetic insecticides is well known as being quite effective causing mosquito 60 larvae mortality [9][10][11][12][13]....
