Occurrence ofMycobacterium lepraein Arthropods

The occurrence of phenolic substances in arthropods.

Influence of plant parameters on occurrence and abundance of arthropods in residential turfgrass.

The effect of taxa [common Bermuda grass, Cynodon dactylon (L.); centipedegrass, Eremochloa ophiuroides Munro Hack; St. Augustinegrass, Stenotaphrum secundatum [Walt.] Kuntze; and zoysiagrass, Zoysia spp.], density, height, and weed density on abundance of natural enemies, and their potential prey were evaluated in residential turf. Total predatory Heteroptera were most abundant in St. Augustin...

Invasive arthropods.

Many arthropod species have been transported around the globe and successfully invaded new regions. Invasive arthropods can have severe impacts on animal and human health, agriculture and forestry, and the biodiversity of natural habitats as well as those modified by humans. The economic and environmental effects of invasion can be both direct, through feeding and competition, and indirect, suc...

Cognitive Arthropods

Insects are nature’s engineering marvels. They can perform marvellous feats such as jumping many times their own body length, lifting many times their own body weight, moving around even with multiple missing limbs and doing all this with amazing efficiency. It is little wonder then that roboticists have been attempting to replicate nature’s design feat in robots. The primary thrust in the area...

Geotropic Orientation in Arthropods

The creeping of the beetle Tetraopes tetraopthalmus during negatively geotropic orientation shows the angles of orientation (theta) on a surface inclined at alpha degrees to the horizontal to be proportional to sin alpha. The direction of orientation easily suffers temporary reversal to positive as result of handling. Mechanical stability during upward progression should be just possible when K...
