PHEIDOLE ANTS AS POTENTIAL BIOLOGICAL-CONTROL AGENTS OF THE BOLL-WEEVIL, ANTHONOMUS-GRANDIS (COL, CURCULIONIDAE), IN SOUTHEAST BRAZIL
(Blackwell Wissenschafts Verlag Gmbh, 1994-11-01)
This study evaluates the potential of ants as natural biological control agents of the boil weevil (Anthonomus grandis), during the between-season period, in South-east Brazil. Active adults of Anthonomus were experimentally ...
Estudio fitoquímico de la especie Ipomoea hederifolia (Batatilla Roja)
(Ciencias Básicas y Tecnologías - Maestría en Química, 2015-05-07)
Ipomoea hederifolia (Scarlet Morning Glory) is a typical vine of Quindio, known for its great invasive potential to coffee plantations; in the same way it has been found as a regulator of growth in some plantations (cotton ...

Bacillus spp. como promotores de crescimento na cultura do algodão.
(Universidade Estadual Paulista (Unesp), 2018-03-09)
O uso contínuo de fertilizantes minerais na agricultura promove o excesso de nutrientes como fósforo, nitrogênio e potássio o que ocasiona danos ao ecossistema e leva à alteração da microbiota do solo. Além disso, existe ...
Influence of cellulose nanofibrils on soft and hard segments of polyurethane/cellulose nanocomposites and effect of humidity on their mechanical properties
(Elsevier B.V., 2014-12-01)
Cellulose nanofibrils (CNFs) were prepared by sulfuric acid hydrolysis from cotton microfibers, and used to prepare polyurethane (PU) nanocomposites by mixing CNFs and PU water suspensions. CNFs as nanofillers improved the ...
Imagens aéreas multiespectrais na identificação de zonas de manejo em áreas de algodão para aplicação localizada de insumos
(2011)
Crop yield is influenced by several factors with variability in time and space that are associated with the variations in the plant vigor. This variability allows the identification of management zones and site-specific ...
Ergonomic Analysis of Visual and Tactile Information of Materials Used in the Manufacture of Toys
(2015-01-01)
Products intended specifically for children began to be developed in the second half of the seventeenth century, driven by a change in the adult's view of the role of children in society. Over time it was noted that children ...
Higher spin analogs of linearized topologically massive gravity and linearized new massive gravity
(2021-10-15)
We suggest a new spin-4 self-dual model (parity singlet) and a new spin-4 parity doublet in D=2+1. They are of higher order in derivatives and are described by a totally symmetric rank-4 tensor without extra auxiliary ...
