A TECHNIQUE FOR SELECTIVELY MARKING AQUATIC INSECTS WITH 32 P

A novel technique for the individual marking of smaller insects

Many ecological studies of insects depend on marking. Marks can be simple, i.e., to identify the released specimens in a mark–release–recapture experiment or individual if more detailed data is sought. Simple marks include ink and paint spots (Wineriter & Walker, 1984; Wojcik et al., 2000), dusting with fluorescent powder (Sinsko & Craig, 1979; Reinecke, 1990; Service, 1993), amputating part of...

Aquatic Insects: Hemimetabolous Insects – Plecoptera

Aquatic insects as a vector for Mycobacterium ulcerans.

Mycobacterium ulcerans is an emerging environmental pathogen which causes chronic skin ulcers (i.e., Buruli ulcer) in otherwise healthy humans living in tropical countries, particularly those in Africa. In spite of epidemiological and PCR data linking M. ulcerans to water, the mode of transmission of this organism remains elusive. To determine the role of aquatic insects in the transmission of ...

Methods for marking insects: current techniques and future prospects.

Tracking the movement of insects in their natural habitat is essential for understanding their basic biology, demography, and ethology. A wide variety of markers have been used to assess insect population dynamics, dispersal, territoriality, feeding behavior, trophic-level interactions, and other ecological interactions. The ideal marker should persist without inhibiting the insect's "normal" b...

5. Diapause in Aquatic Insects, with Emphasis on Mosquitoes

Diapause is the primary factor synchronizing insect life cycles with seasonal changes in the environment. Diapause is the major factor regulating the timing of growth, development, and reproduction, both before and after the period of dormancy. Many definitions of diapause may be found in the literature. Tauber et al. (1986) define diapause as “a neurohormonally mediated, dynamic state of low m...
