1. Bioactivity of essential oils from Artemisia against Diaphania hyalinata and its selectivity to beneficial insects
ABSTRACT: The demand for effective insecticides in pest control with low toxicity to the non-target organisms, such as natural enemies and pollinators, is increasing steadily. A good alternative for synthetic insecticides is natural compounds, including essential oils (EO). This work assessed toxicity of essential oils extracted from Artemisia annua, A. absi

2. Pyrethroid insecticide residue in ‘Grande Naine’ banana peel and pulp during maturation
Abstract In banana farming, the bagging of bunches with bags impregnated by pyrethroid insecticide is a practice that prevents damage to fruits caused by insect pests. The aim of this study was to monitor the presence and permanence of bifenthrin residue during the maturation of ‘Grande Naine’ banana by gas chromatography coupled to mass spectrometer in

3. Assessment of the Toxicity of Sub-chronic Low and High Doses of the Bio-insecticide Spinosad on the Liver, Kidney and the Cerebellum in Male Albino Mice
ABSTRACT Spinosad (SPD) is a highly selective insect control product. However, it was reported that SPD has toxicity toward other non-target organisms. This study was conducted to address the toxic effect of two sub-chronic low and high doses; 35 and 350 mg/kg SPD on some biochemical, histological and immunohistochemical parameters of the liver, kidney and c

4. LABORATORY AND FIELD EVALUATION OF A CYPERMETHRIN-BASED INSECTICIDE FOR THE CONTROL OF ALPHITOBIUS DIAPERINUS PANZER (COLEOPTERA: TENEBRIONIDAE) AND ITS IN-VITRO EFFECTS ON BEAUVERIA BASSIANA BALS. VUILL. (HYPOCREALES: CORDYCIPITACEAE)
ABSTRACT The control of Alphitobius diaperinus is based mainly on chemical insecticides, and the indiscriminate and incorrect use of these products has led to failures in insect control. Thus, it is important to monitor the efficiency of the products available on the market and to develop alternative insect control strategies. The present study evaluated the

5. Vector control intervention towards interruption of transmission of Chagas disease by Rhodnius prolixus, main vector in Guatemala
In Guatemala, the Ministry of Health (MoH) began a vector control project with Japanese cooperation in 2000 to reduce the risk of Chagas disease infection. Rhodnius prolixus is one of the principal vectors and is targeted for elimination. The control method consisted of extensive residual insecticide spraying campaigns, followed by community-based surveillan

6. Parâmetros biológicos do predador Podisus nigrispinus (Heteroptera: Pentatomidae) exposto ao piretróide Deltametrina no estágio ninfal / Biological parameters of the predator Podisus nigrispinus (Heteroptera: Pentatomidae) exposed to the pyrethroid Deltamethrin on the nynphal stage
A deltametrina pode ser seletiva a inimigos naturais, como para o predador Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) que é importante no controle de pragas em sistemas agrícolas e florestais. O objetivo foi avaliar o efeito do inseticida seletivo deltametrina aplicado manualmente em folhas de eucalipto, em concentrações que correspondem a

7. Study of the insecticide and pro-inflammatory activity of lectin isolated from annona coriacea mart seeds / Estudo da atividade inseticida e pro-inflamatoria da lectina isolada de sementes de Annona coriacea Mart
Lectins are a group of proteins and/or glycoproteins, which exhibit specific and reversible carbohydrate-binding activities. Studies have demonstrated that such proteins possess important biological activities including insecticide activity as well as immunological and physiological responses in animals. In this investigation, our aim was to compare the effe

8. Desenvolvimento e reprodução do predador Brontocoris tabidus (Heteroptera: Pentatomidae) no campo após exposição à deltametrina / Development and reproduction of the predator Brontocoris tabidus (Heteroptera: Pentatomidae) in field conditions after exposition to deltamethrin
Insecticide usage can have a detrimental impact on the development and reproduction of natural enemys populations. Pyrethroids such as deltamethrin is widely used in agroecossystems and forest plantations where has shown selectivity to beneficial insects such as predatory bugs. The soldier bug Brontocoris tabidus (Signoret, 1852) (Heteroptera: Pentatomidae)

9. Utilização do conceito de fugacidade na previsão do comportamento ambiental do carbosulfan e do carbofuran na cultura do arroz irrigado
Pesticide use to control pests, diseases and weeds is steadily increasing due to a general food demand increase, cropping area limitation, and manpower availability. Pesticide application without a sound knowledge may hazard environment and human health. Regulatory agencies enforces that, before a new product releasing to the market for agricultural use, int

10. Resistance-associated point mutations in insecticide-insensitive acetylcholinesterase.
Extensive utilization of pesticides against insects provides us with a good model for studying the adaptation of a eukaryotic genome to a strong selective pressure. One mechanism of resistance is the alteration of acetylcholinesterase (EC 3.1.1.7), the molecular target for organophosphates and carbamates. Here, we report the sequence analysis of the Ace gene

11. Diazinon Resistance, Fluctuating Asymmetry and Fitness in the Australian Sheep Blowfly, Lucilia Cuprina
Genetic evidence suggests that the evolution of resistance to the insecticide diazinon in Lucilia cuprina initially produced an increase in asymmetry. At that time resistant flies were presumed to be at a selective disadvantage in the absence of diazinon. Subsequent evolution in natural populations selected modifiers to ameliorate these effects. The fitness

12. Entomopathogenic fungi for mosquito control: A review
Fungal diseases in insects are common and widespread and can decimate their populations in spectacular epizootics. Virtually all insect orders are susceptible to fungal diseases, including Dipterans. Fungal pathogens such as Lagenidium, Coelomomyces and Culicinomyces are known to affect mosquito populations, and have been studied extensively. There are, howe
