Luego, con la segunda aplicacion de insecticida (Lufenuron
) la poblacion de aranas volvio a disminuir, encontrandose en la ultima evaluacion antes de esta aplicacion 60 individuos y luego de esta 39 individuos (Tabla 1).
The focus of the present study was to evaluate the effect of post-treatment temperature on the toxicity of four insecticides viz., spinosad, emamectin benzoate, lufenuron
is an oral medication that can be used to halt the development of fleas--it will not kill adult fleas.
These include Abamectin + Chlorantraniliprole (e.g., Voliam Targo 063 SC), Lufenuron
(such as Match 50EC), Chlorantraniliprole (such as Coragen 20SC), Emamectin benzoate (e.g., Prove 1.92EC), Pyriproxyfen (e.g., Profen 10.8EC) and Acephate (e.g., Orthene Pellet).
molesta in Brazil has been carried out mainly using organophosphorate insecticides (chlorpyrifos and phosmet) and insect growth regulators (lufenuron
and novaluron) (ARIOLI et al., 2010).
Traditional management of adult flea infestations on animals, during the past 15 y is by topical and oral applications of insecticides such as fipronil, imidacloprid, selamectin, and most recently by insect growth regulators (IGRs) such as lufenuron
[2, 9, 11-16].
Both are made by Virbac Animal Health of Fort Worth, Texas, and both contain the IGR lufenuron
, formerly offered by itself in another veterinary prescription product named Program.
Effect of the insecticides abamectin and lufenuron
on eggs and larvae of Chrysoperla externa under laboratory conditions.
In contrast, Saeed et al.,  assessed the toxicity of chlorpyrifos along with cypermethrin, lufenuron
, and emamectin benzoate on 2nd instar larvae of Spodoptera exigua field population after 72-h exposure, they found that chlorpyrifos was the least toxic pesticide ([LC.sub.50] = 175 mg/l) and the most potent pesticide was emamectin benzoate ([LC.sub.50] = 0.005 mg/l).
Therefore, present investigation was designed to estimate the quantitative losses occurred in advance genotypes of wheat rice and maize and to investigate the insecticidal effect of seven insect growth regulators viz., lufenuron
, flufenoxuron, pyriproxyfen, tebufenozide, methoxyfenozide, triflumuron and buprofezin against T.
