Asymmetry of mating behaviour affects copulation success in two stored-product beetles
(2017)Lateralization (i.e. left–right asymmetries in the brain and behaviour) has been documented in all vertebrate classes, while evidences for invertebrates are limited. To the best of our knowledge, there is no information ... -
Bioassays with diatomaceous earth formulations: Effect of species co-occurrence, size of vials and application technique
(2012)Two series of laboratory bioassays were carried out in order to evaluate the effect of the simultaneous presence of two insect species inside the experimental vials and the effect of different sizes (50, 65, 90, 145 mm in ... -
Combining electrostatic powder with an insecticide: effect on stored-product beetles and on the commodity
(2016)BACKROUND: The opportunity to reduce the amount of pirimiphos-methyl applied to grain by formulating it in an electrostatic powder was investigated. The insecticidal efficacy of pirimiphos-methyl in EC formulation or ... -
Effect of Short Exposures to Spinetoram Against Three Stored-Product Beetle Species
(2012)Laboratory bioassays were carried out to evaluate the effectiveness of two formulations of spinetoram, water dispersible granules (WG), and suspension concentrate (SC-NC), against three major stored-grain beetle species, ... -
Effect of temperature and relative humidity on the efficacy of spinetoram for the control of three stored product beetle species
(2013)The effect of temperature and relative humidity (r.h.) on the efficacy of spinetoram on wheat was investigated against three stored product insect species. Laboratory bioassays were conducted on wheat in all combinations ... -
Effect of uneven distribution of spinetoram-treated wheat and rice on mortality and progeny production of Rhyzopertha dominica (F.), Sitophilus oryzae (L.) and Tribolium confusum Jacquelin du Val
(2012)Laboratory bioassays were carried out in order to evaluate the effectiveness of spinetoram on rice and wheat in layer and mixture treatment applications against three major stored-grain beetle species, Rhyzopertha dominica, ... -
Evaluation of three novel diatomaceous earths against three stored-grain beetle species on wheat and maize
(2015)The insecticidal effect of three diatomaceous earths (DEs), that contained different active ingredients, was evaluated under laboratory conditions for the control of adults of the lesser grain borer, Rhyzopertha dominica ... -
From lethality to mortality: exploring the “grey area” of knockdown as an efficacy indicator of different insecticides against major storage insects using a lethality index
(2018)In the present work, a lethality index was applied for the evaluation of three insecticides with different modes of action, i.e., thiamethoxam, chlorfenapyr and lambda-cyhalothrin, as surface treatment against adults of ... -
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 diatomaceous earth and pirimiphos-methyl against phosphine-susceptible and phosphine-resistant populations of two stored product beetle species
(2021)In the present study, we evaluated the insecticidal efficacy of diatomaceous earth (DE) and pirimiphos-methyl for the control of phosphine-susceptible and phosphine-resistant populations of Tribolium castaneum (Herbst) and ... -
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 ... -
