“…The method is also advantageous because the insects do not have to be individually handled, marked or recovered. The first such studies were conducted with mosquitoes (Zukel 1945; Chang 1946; Pal 1947; Reeves, Brookman & Hammon 1948), tsetse flies (Jewell 1958) and aphids (Post & Anderson 1950). More recently, this approach has been employed in movement studies of parasitoid wasps (Corbett & Rosenheim 1996) and a wide range of Coleopteran pests of crops and forests (Gara 1967; Schmitz 1980; Linton et al .…”

Summary1. Rangeland grasshopper movement was studied in Wyoming, USA, with respect to the biological and ecological factors (population density, developmental stage and weather) in¯uencing net displacement and directionality. 2. A novel adaptation of the mark±recapture method was developed to monitor grasshopper dispersal. The method used¯uorescent powder and resighting marked grasshoppers in the ®eld with ultraviolet light, rather than physical recapturing of individuals. 3. Rangeland grasshoppers exhibited a strong tendency for directional movement. Adult grasshoppers demonstrated a signi®cant tendency for dispersal in a northwesterly direction across a range of population densities (5±8, 10±15 and r 18 grasshoppers m ±2 ). Although not a de®nitive explanation, weather might have in¯uenced this behaviour, as the grasshoppers consistently moved upwind. 4. The mean displacement of grasshoppers in a 36-h period ranged from 2´3 m in nymphs to 3´7 m in adults, with the distance of displacement being positively correlated with population density.5. An understanding of grasshopper movement in terms of directionality and displacement has immediate applicability to reduced agent±area treatments for rangeland grasshopper management.

“…The various techniques for marking and tracking invertebrates are reviewed by Lavandero et al (2004). These methods include colour marking (Dudley & Searles 1923), fluorescent compounds (Pal 1947), dyes in artificial diet (Graham & Mangum 1971) and genetic markers (Hausermann et al 1971). Some of the problems associated with these marking methods include: whether the insects are physically large enough to mark; moulting and changes in life stage of the insects over the duration of the experiment; the toxicity of the marker to the insect and; the extensive research and preparation time.…”

A simple and effective marking technique is an invaluable tool for tracking the movement of invertebrates in the field. In order to do this, the technique must be validated in a controlled setting. In the first study, two soft bodied herbivores with different feeding strategies and two of their insect predators, also with different feeding strategies, were marked with rubidium (Rb), an elemental marker previously shown to be effective in marking herbivorous invertebrates. The naturally occurring concentration of Rb was determined for both the herbivores and their predators. Rb concentrations were determined in (1) the herbivore species over several days of feeding on rubidium chloride (RbCl) marked plants; (2) in the predatory species immediately after consuming prey marked at different rates with Rb; and (3) in the predatory species for several days after consuming a single meal of Rb marked prey. The concentration of Rb within the marked herbivores was found to be significantly higher than the naturally occurring concentration after eating RbCl marked plants for to up 8 days. A significantly higher concentration of Rb was found in both predators when fed prey that had been on the RbCl sprayed plants for 2 or 8 days compared with naturally occurring concentrations. There was also a significant difference between the Rb concentrations in the controls and each of days 5, 10 and 15 since feeding in both predators. A second smaller study was carried out to examine the effect of feeding Rb marked prey to spiders. The concentration of Rb in the spiders fed marked prey was significantly higher than that of the controls. This suggests that Rb is an effective way of marking both herbivores and their insect and arachnid predators enabling them to be tracked in the field and to determine their movements across habitats.

“…L'un d'entre nous (Croset et coll., 1980), avait dejä employe de tels pigments pour l'etude de la dispersion des moustiques du genre Aedes dans la nature: en fait, le marquage fluorescent fut d'abord employe par les entomologistes travaillant sur les Dipteres (Zuckel, 1945;Pal, 1947). Par la suite, de nombreux mammalogistes ont melange des colorants fluorescents ä des appäts (Frantz, 1972;Evans et Griffith, 1973) pour marquer les feces et les urines des rongeurs dans le but d'etudier la taille de leurs domaines vitaux.…”

Les petits rongeurs marques ä l'aide de poudres fluorescentes peuvent etre suivis par les traces qu'ils laissent au sol; leurs deplacements sont ainsi materialises, leurs nids et leurs terriers localises.Les grands deplacements observes grace ä cette technique, chez toutes les especes etudiees, on t amene les auteurs ä modifier leurs protocoles d'echantillonnage des Murides.Cette technique s'est revelee efficace chez de nombreuses especes vivant dans diffe'-rents types de milieux (Mus musculus domesticus dans les dunes sableuses, Mus spre· tus et Apodemus sylvaticus dans la garrigue mediterrane'enne, Proechimys cuvieri en foret tropicale guyanaise, Hylomyscus stella et Hylomyscus fumosus en foret tropicale gabonaise).L'utilisation de ces pigments a egalement permis l'etude de la dispersion des glands par Apodemus sylvaticus dans la chenaic mediterraneenne.
