With warmer temperatures, insect infestation will become a greater problem throughout the northern parts of the Holarctic. Another potential effect of global warming to northern ecosystems is the melting of permafrost. This can have significant effects on the plant communities that are adapted to the frozen soil, and may also have implications ...
Infestations can be classified as either external or internal with regards to the parasites' location in relation to the host. External or ectoparasitic infestation is a condition in which organisms live primarily on the surface of the host (though porocephaliasis can penetrate viscerally) and includes those involving mites, ticks, head lice and bed bugs.
Entomology (from Ancient Greek ἔντομον (entomon) 'insect' and -λογία () 'study') [1] is the scientific study of insects, a branch of zoology.In the past the term insect was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans.
Insects are responsible for two major forms of damage to crops. First, there is the direct injury they cause to the plants as they feed on the tissues; a reduction in leaf surface available for photosynthesis, distortion of growing shoots, a diminution of the plant's growth and vigour, and the wilting of shoots and branches caused by the ...
Insects often adapt their nests to reduce parasitism. For example, one of the key reasons why the wasp Polistes canadensis nests across multiple combs, rather than building a single comb like much of the rest of its genus, is to avoid infestation by tineid moths. The tineid moth lays its eggs within the wasps' nests and then these eggs hatch ...
A giant water bug attacking a fish. Insect ecology is the interaction of insects, individually or as a community, with the surrounding environment or ecosystem. [1] This interaction is mostly mediated by the secretion and detection of chemicals (semiochemical) in the environment by insects. [2]
Bed bug infestations are primarily the result of two species of insects from genus Cimex: Cimex lectularius (the common bed bug) and Cimex hemipterus (the tropical bed bug). [3] These insects feed exclusively on blood and, at any stage of development, may survive up to 70 days without feeding. [ 8 ]
Following is an example of a cohort life table based on field data from Vargas and Nishida (1980). [4] The overall mortality rate was 94.8%, but this is probably an underestimate because the study collected the pupae in cups, and these may have protected them from birds, mice, harsh weather, and so on.
