Opuntia ficus-indica, the Indian fig opuntia, fig opuntia, or prickly pear, is a species of cactus that has long been a domesticated crop plant grown in agricultural economies throughout arid and semiarid parts of the world. [3] O. ficus-indica is the most widespread and most commercially important cactus.
The eggs are laid on either the tip of the cactus spine, the cactus leaf, the cladode, or the cactus fruit. [8] Egg sticks that resemble cactus spines develop and hatch in 25–30 days. The gregarious larvae bore into the cactus pad through a single entry hole by chewing through the tough outer cuticle of the cladode. [8]
Opuntia, commonly called the prickly pear cactus, is a genus of flowering plants in the cactus family Cactaceae, many known for their flavorful fruit and showy flowers. [1] Cacti are well-adapted to aridity; however, they are still vulnerable to alterations in precipitation and temperature driven by climate change. [ 2 ]
It is well-adapted to its native desert environment, and the birds can meet their water needs from their diet which consists chiefly of insects, but also of some plant matter. The cactus wren is a poor flier and generally forages for food on the ground. Ornithologists generally recognize seven subspecies, with the exact taxonomy under dispute.
The Cactaceae is a monograph on plants of the cactus family written by the American botanists Nathaniel Lord Britton and Joseph Nelson Rose and published in multiple volumes between 1919 and 1923. It was landmark study that extensively reorganized cactus taxonomy and is still considered a cornerstone of the field. [ 1 ]
Cochineal insects are soft-bodied, flat, oval-shaped scale insects. The females, wingless and about 5 mm (0.20 in) long, cluster on cactus pads. They penetrate the cactus with their beak-like mouthparts and feed on its juices, remaining immobile unless alarmed. After mating, the fertilised female increases in size and gives birth to tiny nymphs ...
The eggs of Chilocorus cacti are about 1 mm (0.04 in) long, oval and grey. The larvae are cylindrical and moult three times, the fourth instar larva being about 6 mm (0.24 in) long; the larvae are black, with a yellowish-brown girdle, and have large black spines on the dorsal surface.
Istocheta aldrichi egg on Popillia japonica (Japanese beetle) Most tachinids are dull colored, resembling house flies Ormia ochracea, notable for its acute directional hearing [10] In many species only one egg is laid on or in any individual host, and accordingly such an egg tends to be large, as is typical for eggs laid in small numbers. They ...
