Effects of Dietary Protein Levels on Reproduction and Food Consumption in the German Cockroach (Dictyoptera: Blattellidae)
نویسنده
چکیده
The effects of four diets (commercial rat food, 5, 25, and 65% protein) on reproduction and daily food consumption of male and female German cockroaches were investigated. Females compensate for low dietary protein levels by elevating consumption rates and reproduce normally. Conversely, a high-protein diet significantly delayed mating in females and resulted in smaller oothecae. Percentage hatch of oothecae and male sexual maturation were unaffected by dietary protein content. Males that were allowed to copulate twice a week, ate more, and died sooner than males allowed to mate only once. The role of diet composition in regulating feeding behavior is discussed.

Nymphal development and adult female reproduction were examined in the German cockroach, Blattella germanica, using a defined artificial diet in which the type of protein was varied. Milk proteins, including casein, supported development poorly compared to meat and plant proteins. Soybean protein supported development better than all other highly purified proteins including vitamin-free casein ...

The German cockroach is an important household insect pest mechanically involved in transmission of a variety of diseases to humans. Different classes of insecticides have extensively been used for its control leading to insecticide resistance development. Hence, for an optimal control of this pest, the status and underlying mechanisms of insecticide resistance should be studied in this group o...

Female brown-banded cockroaches, Supella longipalpa (F.) (Dictyoptera : Blattellidae), failed to elevate consumption rates when fed a 5~o protein diet compared with females fed either 25~o protein or commercial rat food. Adult performance was directly influenced by dietary protein level: Females fed 65 ~o protein died rapidly, while in females fed 5 ~o protein feeding and reproductive rates wer...

An experimental 2.15% imidacloprid gel bait containing approximately 44% water was evaluated in laboratory and field studies against the German cockroach, Blattella germanica (L). In continuous exposure tests, toxicity and presumably bait consumption varied with cockroach stage, deprivation of competitive food, and temperature. The LT50 values for cockroaches provided with competitive food rang...

We examined the effects of 3 active ingredients in baits containing glucose on a behaviorally resistant (glucose-averse, T-164) strain of Blattella germanica L. Baits with glucose and hydramethylnon or chlorpyrifos killed few T-164 individuals; however, ÞpronilÐglucose baits killed 60% of the cockroaches by day 14. Although ingestion levels were low, ÞpronilÐglucose baits were consumed more tha...
