Impacts of Storicide II on internal feeders of Brown rice J. Stored Prod. Res. (IF 2.123) Pub Date : 2020-12-26 Erin D. Scully; Alison R. Gerken; Adriane Fifield; Valerie Nguyen; Nicholas Van Pelt; Frank H. Arthur
Protectants applied to grain can reduce damage caused by insect feeding during storage. Although these protectants are effective against many external feeders, they may also reduce damage caused by internal feeders as they often interact with the exterior surface of the grain during their larval or adult stages to feed or oviposit. For this study, we investigated impacts of Storicide® II applied to

An effective method of bulk materials moisture measurement using capacitive sensors J. Stored Prod. Res. (IF 2.123) Pub Date : 2020-11-04 Oleksandr Zabolotnyi; Mikola Koshevoi
When we speak about capacitance moisture meters for bulk materials we have to face with different values of dielectric permittivity for different bulk materials in dehydrated state, what causes a method error that can be named ‘type uncertainty’. Besides, different varieties of the same material have different values of dielectric permittivity, which depend from geographical origin, processing conditions

Auto-confusion of Ephestia cautella (Walker) infesting dried fruits in a confectionery factory store J. Stored Prod. Res. (IF 2.123) Pub Date : 2020-09-07 Pasquale Trematerra; Marco Colacci
We assessed the effectiveness of a pheromone auto-confusion method applied for a three-year study (Years 1–3) in a confectionery factory store infested by almond moths, Ephestia cautella (Walker), based on pheromone traps and the presence of spermatophores in females captured with water traps. The application of Exosect® SP Tab pheromone dispensers, at a rate of 1 tablet per 25 m2 floor area, combined

Effects of lyophilized red cabbage water extract and pH levels on the quality properties of pastırma cemen paste during chilled storage J. Stored Prod. Res. (IF 2.123) Pub Date : 2020-09-06 Muhammet İrfan Aksu; Emre Turan; İhsan Güngör Şat
Pastırma is a dry-cured and dried meat product and its coating with a paste defined as “cemening” is one of the most important stages in the formation of its color and quality. However, discoloration is an important problem during production and storage. In this study, the effects of lyophilized red cabbage water extracts (LRCWE; 0.0%, 0.4%, 0.8% and 1.2%) and pH values (4.0, 4.5, 5.0, 5.5 and 6.0)

Effect of radio frequency heating on the mortality of Rhizopertha dominica (F.) and its impact on grain quality J. Stored Prod. Res. (IF 2.123) Pub Date : 2020-09-04 Miao Cui; Weiwei Sun; Liyuan Xia; Zhongming Wang; Yang Cao; Yi Wu
The use of radio frequency (RF) heating to reach temperatures lethal to stored product pests has significant potential. We examined the lethal effects of RF on the stored grain pest, Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae), under four different RFs, three types of grain, and different moisture contents of rice. The quality of two rice cultivars, after RF heating, was also tested. When

Rolliniastatin-1, a bis-tetrahydrofuran acetogenin: The major compound of Annona mucosa Jacq. (Annonaceae) has potent grain-protective properties J. Stored Prod. Res. (IF 2.123) Pub Date : 2020-09-02 Leandro do Prado Ribeiro, Gabriel Luiz Padoan Gonçalves, Keylla Utherdyany Bicalho, João Batista Fernandes, José Djair Vendramim
The widespread use of synthetic insecticides results in insecticide-resistant populations of maize weevil, Sitophilus zeamais Motsch. (Coleoptera: Curculionidae), a primary pest species of stored corn worldwide. Thus, new active ingredients with different modes of action are needed for integrated pest management (IPM) of stored grains. Thus, toxicological bioassays (using S. zeamais as bioindicator)

Individual and combined effects of insecticides, inert dusts and high temperatures on Callosobruchus maculatus (coleoptera: Chrysomelidae) J. Stored Prod. Res. (IF 2.123) Pub Date : 2020-08-30 Roghaiyeh Karimzadeh, Mina Javanshir, Mir Jalil Hejazi
In this study individual and combined effects of some chemical and physical factors including cypermethrin, dichlorvos, ash, kaolin and high temperatures were assessed on adults of cowpea seed beetle Callosobruchus maculatus (F.) at laboratory conditions. The adults were exposed to the studied factors on concrete arenas prepared in plastic Petri dishes. Twenty up to 24 h old adults were released in

Effects of storage period and temperature on the technological properties, starch digestibility, and phenolic compounds of mung beans (Vigna radiata L.) J. Stored Prod. Res. (IF 2.123) Pub Date : 2020-08-30 Valmor Ziegler, Iasmim de Almeida Veeck, Mariane Lobo Ugalde, Gustavo Heinrich Lang, Jéssica Fernanda Hoffmann, Angela Cristina Mello dos Santos, Maria Eduarda Postingher, Rochele Cassanta Rossi, Cristiano Dietrich Ferreira
This study aimed to evaluate the effects of storage period (0, 2, 4, and 6 months) and temperature (15 °C, 25 °C, and 35 °C) on the germination, vigor, technological properties, starch digestion, and phenolic compound content of mung beans. The germination, vigor, protein solubility, inhibition of the ABTS radicals, and the total free and bound phenolic compound content reduced while cooking time,

Insect pest susceptibility of grains and seeds recently introduced to the Italian market: An experimental evaluation J. Stored Prod. Res. (IF 2.123) Pub Date : 2020-08-30 Filippo Cominelli, Maria Cristina Reguzzi, Rinaldo Nicoli Aldini, Emanuele Mazzoni
To assess the susceptibility of pseudocereals (amaranth and quinoa), minor cereals (teff and millet), and oilseeds (chia and hemp), now commercially available on the European market, to attacks by polyphagous and cosmopolitan insect pests, laboratory tests were set up. Tests involving controlled infestation of seeds, using laboratory-bred insects (Tenebrio molitor, Tribolium confusum, Oryzaephilus

Phosphine resistance in saw-toothed grain beetle, Oryzaephilus surinamensis in the United States J. Stored Prod. Res. (IF 2.123) Pub Date : 2020-08-29 S.G. Gautam, G.P. Opit, C. Konemann, K. Shakya, E. Hosoda
Phosphine (PH3) fumigation resulting in sub-lethal exposure has led to the development of phosphine resistance in many stored-product insect species worldwide and is a major challenge to the continued effective use of phosphine. In 2016 phosphine resistance was found in Tribolium castaneum (Herbst) and Plodia interpunctella (Hübner) collected from California dried fruit and nut processing facilities

Assessment of bruchids density through bioacoustic detection and artificial neural network (ANN) in bulk stored chickpea and green gram J. Stored Prod. Res. (IF 2.123) Pub Date : 2020-08-26 Km. Sheetal Banga, Nachiket Kotwaliwale, Debabandya Mohapatra, V. Bhushana Babu, Saroj Kumar Giri, Praveen Chandra Bargale
Acoustical detection of insects feeding and crawling sounds was used to automatically monitor internal and external grain feeding bruchids in order to assess the growth and density of food legume bruchids (Callosobruchus chinensis and Callosobruchus maculatus) in bulk stored chickpea and green gram. Bruchids hidden inside the grain kernels were detected acoustically through amplification and filtering

The sequence characteristics and functions on regulating trehalose metabolism of two PTP genes in Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) J. Stored Prod. Res. (IF 2.123) Pub Date : 2020-08-25 Bi-ying Pan, Kang-kang Xu, Yu-jia Luo, Yuan-yuan Wang, Min Zhou, Can Li, Bin Tang
Protein tyrosine phosphatase is a type of enzyme commonly found in eukaryotes that specifically hydrolyzes tyrosine phosphate bonds on protein substrates to remove phosphate, thereby regulating protein functions or even cell functions. In this study, we used the model insect Tribolium castaneum to study the sequence characteristics and functions on trehalose metabolism of two PTP proteins in T. ca
