“…This was necessary as the fynbos is woody and not easily sampled using a sweep net, and beating is too harmful on the rare plants in the area (over 300 plants are either endemic to the area or IUCN Red Listed.) A D-vac consists of a collecting bag mounted in the collecting nozzle, which in turn is connected by a 20 cm hose to a 3 horsepower back-pack mounted engine (Dietrick et al 1959;Southwood and Henderson 2000). The nozzle width used in this study was 30 cm.…”

Mountains present particular challenges for biodiversity conservation. Table Mountain is a significant mountain in a global biodiversity hotspot, the Cape Floristic Region. It has outstanding angiosperm diversity and endemism. Yet, aerial and foliage invertebrates in the area have been poorly studied, despite their importance as pollinators and predators. These plant and invertebrate assemblages are under great pressure from human disturbance. Aerial and foliage invertebrates were sampled with a range of techniques. Sites were chosen to make comparisons between vegetation structure and type, elevation and aspect. In total, 216 species from 63 families and 14 orders were recorded. Vegetation structure (fynbos or forest) and elevation were the most important environmental variables for both aerial and foliage invertebrates. Peak time for aerial invertebrate abundance was spring and summer in the fynbos and spring in the forests, while the foliage invertebrates showed very little seasonal variation. There was no correlation between the diversity of aerial and foliage invertebrates. When these results were compared with others on epigaeic invertebrates, it became clear that epigaeic and aerial invertebrates are not correlated, while epigaeic and foliage invertebrates were only partially correlated, but not sufficiently so to consider one as a reliable estimator of the other. The management pointer from this study is that sites at all elevations are vital for the conservation of biodiversity on Table Mountain. Both the aerial and epigaeic/foliage invertebrate assemblages will need to be monitored separately to maintain the mountain's conservation status.

“…The substrates samples (2 kg) were evaluated for midge oviposition and larval development from the centre of the piles at 7-day intervals in the insectary. The Ceratopogonid midge larvae after developing in the organic matter were collected using the Berlese Funnel Traps (Dietick et al, 1959). The substrates were inspected for larger midge larvae (Forcipomyia spp.)…”

Cocoa midges [Forcipomyia sp (Diptera: Cerato-pogonidae)] are major pollinators of cocoa and it is assumed that the number of fertilized pods and the increase in bean numbers may be the approach to enhancing cocoa yield. An insect survey using suction traps was employed to estimate the midge population dynamics in three Caribbean territories. Separate studies were conducted on the cocoa floral and reproductive phenology in addition to the evaluation of several naturally occurring substrates. The results indicated that the insect population as determined by the suction traps were low (27.1 ± 3.37 to 53.5 ± 8.47 transect site). The trees maintained the floral prolificacy even though the pollination [%] was low for Jamaica (0.91), Trinidad (0.88), and Tobago (0.11). However, it was improved when the midge pollinator population was increased with augmentation of substrates of cacao pods [5660] and banana pseudo-stem (1885). This resulted in significant increases in new pods which increased from < 10 pods/tree in the untreated areas to 49 to 76 pods/tree with substrate augmentation. It was evident that the discarded cocoa pod after harvest was a suitable feeding substrate and breeding site for the midge. This information is to be used to advance further studies in plant-pheromones which can serve as attractants to increase pollination/fertilization in cocoa.

“…More recently Remane (1958) has briefly alluded to quantitative sampling of Homoptera Auchenorrhyncha by a vacuum-cleaner type of apparatus driven by a 500 cc. petrol motor, and Dietrick, Schlinger & van den Bosch (1960) have described in more detail another petrol-driven model. In essence, the design of their model is similar to that of Johnson, Southwood & Entwistle (1957), but the scale is much larger; e.g., the suction hose has a diameter of three inches instead of one inch.…”

“…In essence, the design of their model is similar to that of Johnson, Southwood & Entwistle (1957), but the scale is much larger; e.g., the suction hose has a diameter of three inches instead of one inch. Dietrick, Schlinger & van den Bosch (1960) did not measure the efficiency of their machine, but by manually clearing the habitat they were able to take what they called " faunistic samples ", gathering " all possible organisms ". Recently Dietrick (1961) has produced a smaller motorised version of his sampler that can be carried strapped on to the operator's back.…”

“…Both the models designed by Johnson, Southwood & Entwistle (1955, 1957 and Kennard & Spencer (1955) depend on a supply of electrical power; this can be supplied either from the mains or from a generator. Power lines, a generator and also the petrol motor used by Remane (1958) and Dietrick, Schlinger & van den Bosch (1960) are all expensive, and in many situations impracticable. We have therefore tried to devise a hand-operated model dependent only on man-power, and therefore of use in any situation.…”
