This project has an objective to study the biological parameters of Trichogramma pretiosum on eggs of H. armigera. The three strains of T. pretiosum were evaluated: TM, TMC and TLEM, from different places. The experimental establishing was completely randomizing with twenty repeats per treatment, being u...
Abstract The soybean (Glycine max (L.): Fabaceae) is considered the most important agricultural crop in Brazil. Phytophagous tetranychid mites as Mononychellus planki McGregor, Tetranychus ludeni Zacher and T. urticae Koch have been considered pest in soybean crops. Neoseiulus idaeus Denmark & Muma (...
Abstract: Background: Chemical pesticides, widely used in agriculture and vector-borne disease control, have shown toxic effects on the environment and the people in contact with them. Bacillus thuringiensis is a widely used bacterium for alternative and safer control of insect pests. Its toxins are sp...

ABSTRACT Melon is one of the most important vegetable crops in the world. With short cycle in a system of phased planting, phytosanitary control is compromised, and a great volume of agricultural chemicals is used to control vegetable leafminer. Genetic control is an ideal alternative to avoid the damage...

O objetivo deste estudo foi avaliar a atividade predatória do fungo Duddingtonia flagrans contra larvas infectantes (L3) de nematoides gastrintestinais na pastagem e no bolo fecal de equinos, em um período de 21 dias. O delineamento experimental foi inteiramente ao acaso, com três grupos tratados (G1,...
Abstract The purpose of this study was to evaluate the predatory activity of the nematode Butlerius spp. and fungal isolates of Duddingtonia flagrans, Clonostachys rosea, Arthrobotrys musiformis and Trichoderma esau against H. contortus infective larvae (L3) in grass pots. Forty-eight plastic gardening p...
Introducción: en la actualidad, nuevas tendencias tecnológicas e iniciativas se están presentando en el desarrollo de productos insecticidas derivados de productos naturales, y de nuevos agentes antimicrobianos, dado que poseen bioactivos que son selectivos, biodegradables y tienen menores efectos adv...
Dentre os agravos à saúde que têm acometido a população brasileira, destaca-se as cometidas pelo Aedes Aegipyt, a qual requer ações de controle integradas e participativas. Esse estudo analisou o Levantamento do Índice Rápido pelo Aedes aegypti (LIRAa) nos últimos dois anos da zona urbana do mu...
Introducción: el aumento de enfermedades transmitidas por mosquitos se ha asociado a cambios globales: el crecimiento de la población, la urbanización y el cambio climático. Dentro de las alternativas para evitar epidemias están el control químico y biológico.
Objetivos: determinar las concentraci...
