Opis:: Humans and animals come into contact with various compounds in their natural environment. Most of the encountered substances are neutral, yet some may carry adverse health effects. The ingested food may be a source of harmful substances, including benzoquinones which, as shown by research results cited in this paper, demonstrate toxic, carcinogenic and enterotoxic activity. This group of compounds is inclusive of 2-methyl-1,4-benzoquinone (MBQ) and 2-ethyl-1,4-benzoquinone (EBQ), defensive secretions of the confused flour beetle (Tribolium confusum J. du V) and the red flour beetle (Tribolium castaneum Herbst). Benzoquinones have a carcinogenic effect, they are inhibitors of growth of various microorganisms, they produce a self-defense mechanism in threat situations and affect population aggregation. As noted by the referenced authors, the properties of benzoquinones have not been fully researched to this date.

Opis:: The study was conducted to determine the biodegradation of Expanded Polystyrene (EPS) (Styrofoam) Blocks as feedstock to Tribolium castaneum (Red Flour Beetle) Imago. Three-hundred-sixty (360) Tribolium castaneum (Red Flour Beetle) Imagos were collected and acclimatized for two days before being exposed to experimentation. Incubation boxes were made using plywood. Three set-ups were prepared, with 30 Tribolium castaneum (Red Flour Beetle) each. Seven (7) grams of Styrofoam Block were placed in Set-up 1, seven (7) grams of Styrofoam and seven (7) grams of Rice grain Bran in Set-up 2 and seven (7) grams of Rice grain Bran in Set-up 3 with three replications each. Mean percent mass loss of Styrofoam and Rice grain Bran, mean percent mass loss and survival rate of Tribolium castaneum (Red Flour Beetle) were measured at 5th, 10th, 15th and 20th day incubation periods. Maximum mean percent mass loss in the different set-ups was observed at the 10th, 15th and 20th incubation period, with loses of 7.14%, 10.71% and 10.71%, respectively. Meanwhile, maximum mean percent increased weight of Tribolim castaneum (Red Flour Beetle) was observed at the 10th day incubation period, with 13.51%, 44.44% and 37.93%, respectively. Microscopic observation, of a dark white smear on the gut of the specimen indicates that Tribolium castaneum (Red Flour Beetle) Imago really masticate and biodegrade the Expanded Polystyrene (EPS) (Styrofoam) blocks. The survival rate of Tribolium castaneum (Red Flour Beetle) in the diverse set-ups showed no significant difference. This implies that ingestion of Styrofoam Block had no lethal effects on the natural weight variation and health of the Tribolium castaneum (Red Flour Beetle). Hence, results indicate that Expanded Polystyrene (EPS) (Styrofoam) Block can be a feedstock for Tribolium castaneum (Red Flour Beetle).

Opis:: The artificially made kernels from ground wheat grain, commercial wheat starch and wheat proteinaceous α-amylase inhibitors in different proportions were used as feed for adults of the granary weevil (Sitophilus granarius L.). In the case of larvae of the confused flour beetle (Tribolium confusum Duv.) and the Mediterranean flour moth (Anagasta kuehniella Zell.) the friable feed mixture were used. The survival of S. granarius adults has not been correlated with the soluble proteins extracted from wheat and amylolytic activity located in this protein fraction. On the other hand the weight of dust (the index of feeding intensity) produced during feeding has depended on the presence of α-amylase and trypsin inhibitors in wheat-based feed. A. kuehniella larvae have not developed at all on feed consisted of 50% wheat starch and 50% of crude a-amylase inhibitors from wheat. The same feed has caused 15.1 days of extension in development time of T. confusum larvae. lt attests to specific native enzymatic apparatus existing in alimentary canals of three damaging grain species which can overcome some obstacles even if extremely highly active insect α-amylase inhibitors were present in feed. However, the sufficient nutrient should be available in feed compounds. Nevertheless, some reduction of insects population can be expected.
Sztuczne ziarna zrobione z handlowej skrobii pszennej i białkowych inhibitorów α-amylaz wymieszanych w różnych proporcjach oraz czyste ziarno pszenicy stanowiły pokarm wołka zbożowego (Sitophilus granaris L.). Dla larw trojszyka ulca (Trbolium confusum Duv.) i mklika mącznego (Anagasta kuchniella Zell.) te same produkty podawano w postaci sypkiej. Procent przeżywalności chrząszczy wołka zbożowego nie zależał od zawartości białka rozpuszczalnego ani od aktywności amylolitycznej pokarmu. Z drugiej strony ilość pyłu wytworzonego w czasie żerowania (wskaźnik intensywności żerowania) zależał od obecności inhibitorów α-amylazy i trypsyny. Larwy mklika mącznego nie kończyły rozwoju na pokarmie zawierającym 50% skrobii pszennej i 50 inhibitorów α-amylazy. Ten sam pokarm powodował przedłużenie rozwoju larw trojszyka ulca o 15,1 dnia. To świadczy o istnieniu wrodzonego, specyficznego aparatu enzymatycznego w przewodzie pokarmowym testowanych owadów, który może pokonać nawet ekstremalnie wysoką aktywność inhibitorów α-amylazy obecnych w pokarmie. Efektem działania inhibitorów może być tylko redukcja liczebności populacji.
