Behavioral interactions between Sitophilus zeamais and Tribolium castaneum: the first colonizer matters
(2015)There is lack of knowledge on the interactions between kernel aging and the simultaneous infestation by insects, both internal and external feeders. In the present paper, we report results obtained in arena-olfactometer ... -
Behavioral responses of Sitophilus zeamais Motschulsky adults to conditioned grain kernels
(2013)Laboratory experiments were conducted in order to assess the intra- and inter-specific interactions in cereal kernels and behavioral responses of maize weevil (Sitophilus zeamais) adults. For that purpose, conditioning of ... -
Distribution and migration of insects and mites in flat storage containing wheat
(2001)Studies were conducted in a flat storeroom in central Greece, filled with approx., 90 tons of wheat, in order to evaluate insect and mite species abundance, and changes in population density and distribution among sampling ... -
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, ... -
Efficacy of a Combination of Beta-Cyfluthrin and Imidacloprid and Beta-Cyfluthrin Alone for Control of Stored-Product Insects on Concrete
(2013)The insecticidal effect of Temprid, a formulation that contains beta-cyfluthrin and imidacloprid, was tested on concrete for control of seven stored-product insect species: the rusty grain beetle, Cryptolestes ferrugineus ... -
Efficacy of Insect Growth Regulators as Grain Protectants against Two Stored-Product Pests in Wheat and Maize
(2012)Insect growth regulators (IGRs) (two juvenile hormone analogues [fenoxycarb and pyriproxifen], four chitin synthesis inhibitors [diflubenzuron, flufenoxuron, lufenuron, and triflumuron], one ecdysteroid agonist [methoxyfenozide], ... -
Efficacy of two formulations of pirimiphos-methyl as surface treatment against Sitophilus granarius, Rhyzopertha dominica, and Tribolium confusum
(2014)In the present work, the insecticidal effect of two pirimiphos-methyl formulations [emulsifiable concentrate (EC) and capsule suspension (CS)] as surface treatment on concrete, plywood, galvanized metal, plastic, and ceramic ... -
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 ... -
Influence of Commodity Type, Percentage of Cracked Kernels, and Wheat Class on Population Growth of Stored-Product Psocids (Psocoptera: Liposcelidae)
(2010)Differences in stored-product psocid progeny production as a function of commodity type, percentage of cracked kernels, and wheat class were examined using laboratory bioassays. Population growth of Liposcelis bostrychophila ... -
Laboratory evaluation of diatomaceous earth deposits mined from several locations in central and southeastern Europe as potential protectants against coleopteran grain pests
(2011)Diatomaceous earth (DE) deposits from regions of central and southeastern Europe were evaluated for their insecticidal efficacy against Sitophilus oryzae (L.) (Coleoptera: Curculionidae), Rhyzopertha dominica (F.) (Coleoptera: ... -
Lesser grain borers, Rhyzopertha dominica, select rough rice kernels with cracked hulls for reproduction
(2012)Tests were conducted to determine whether the lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrychidae), selects rough rice (Oryza sativa L. (Poales: Poaceae)) kernels with cracked hulls for reproduction ... -
Long-Term Residual Efficacy of Spinetoram on Concrete and Steel Surfaces for the Management of Three Stored Product Beetle Species
(2015)In this study, the residual efficacy of spinetoram on concrete and galvanized steel surfaces was evaluated under fixed laboratory conditions against the rice weevil, Sitophilus oryzae (L.), the confused flour beetle, ... -
Persistence and efficacy of spinetoram against three major stored grain beetle on wheat
(2015)The insecticidal efficacy of spinetoram at concentrations of 0.1, 1 and 5 ppm on wheat was investigated against adults of three major stored-grain species, Sitophilus oryzae (L), Rhyzopertha dominica (F.) and Tribolium ... -
Spatial Associations of Insects and Mites in Stored Wheat
(2011)The spatial association pattern of insect and mite populations in a steel bin containing stored wheat, Triticum durum Desf., in central Greece, was studied using the Spatial Analysis by Distance IndicEs (SADIE). The ... -
Transformation and attachment of Beauveria bassiana conidia on the cuticle of Tribolium confusum and Sitophilus oryzae in conjunction with diatomaceous earth
(2012)Agrobacterium tumefaciens-mediated transformation (AMT) was used in order to create fluorescent conidia of Beauveria bassiana (Balsamo) Vuillemin (Ascomycota: Hypocreales). From the fungal transformants, one Enhanced Green ...
