Influence of grain type on the efficacy of spinetoram for the control of Rhyzopertha dominica, Sitophilus granarius and Sitophilus oryzae
(2015)The efficacy of spinetoram against adults of three major stored grain beetle species, the lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrychidae), the granary weevil, Sitophilus granarius (L.) (Coleoptera: ... -
Insecticidal effect of Dittrichia viscosa lyophilized epicuticular material against four major stored-product beetle species on wheat
(2020)We examined the insecticidal effect of lyophilized epicuticular material of the ruderal species Dittrichia viscosa in four major stored-product beetle species. Furthermore, the potential of this material in progeny production ... -
Insecticidal effect of Keepdry (R) for the control of Sitophilus oryzae (L.) (Coleoptera: Curculionidae) and Rhyzopertha dominica (F.) (Coleoptera: Bostrychidae) on wheat under laboratory conditions
(2014)Laboratory bioassays were conducted to evaluate the insecticidal efficacy of the diatomaceous earth (DE) Keepdry (R) grain protectant against Sitophilus oryzae (L) (Coleoptera: Curculionidae) and Rhyzopertha dominica (F.) ... -
Insecticidal effect of spinetoram against six major stored grain insect species
(2012)Spinetoram is a novel insecticide that belongs to the spinosyn class of insecticidal chemicals. The efficacy of spinetoram against numerous insect pest species in a variety of field crops has been well demonstrated. However, ... -
Insecticidal efficacy of phosphine fumigation at low pressure against major stored-product insect species in a commercial dried fig processing facility
(2016)We investigated the application of phosphine at low pressure for various exposure durations against major stored-product insects in a commercial dried fig processing facility in Central Greece. Trials were carried out ... -
