Human-induced environmental stress can impair freshwater ecosystems by destroying them or altering in negativeways. Laws and ordinances that Kenya's water resources' correct management utilization were prompted worries about the of bodies.

An experiment was performed to test the influence of two factors on assortative mating in the Jewel wasp (Nasonia vitripennis): (1) inherited eye-color genotype, and (2) conditioned foraging phenotype. To determine the female choice of sires, genetically marked wasps were used of two recessive mutant eye-color genotypes: white or red. Each female (of independently crossed eye-color and juvenile...

Males of Limnogonus aduncus were found to have the sex chromosome system X0 and chromosome number 2n = 23 (22A + X0). Testis cells were stained with lacto-acetic orcein and silver nitrate so that changes in the morphology and degree of staining of the heteropicnotic chromatin and the nucleolar material could be observed during meiosis and spermiogenesis. These structures share the same nuclear ...

Heteropteran predators constitute an important component of predatory guilds in terrestrial and aquatic ecosystems. Most heteropteran species have generalist diets, and intraguild predation has been documented in most heteropteran families. Zoophytophagous species also frequently engage in intraguild interactions. An increase in extraguild prey density is often predicted to reduce intraguild pr...

Complete trypanosomatid life cycles have been studied for a handful of species, mainly those medical importance (i.e., Leishmania and Trypanosoma).The vast majority trypanosomatids infect insects the orders Diptera Hemiptera, although representatives at least three additional implicated as specific hosts.While monoxenous develop in insect intestinal tract, some them also live Malpighian tubules...
