We further discussed the correlation of spider existence with the crop vegetation structures and architectural features. This will be further discussed in this chapter together with our current results obtained from the botanical garden, dragon fruit, and herbal garden plantations which are suggesting some potential biocontrol agents for agricultural ecosystems belonging to the family groups of Araneidae, Lycosidae, Oxyopidae, Tetragnathidae, Thomisidae, and Salticidae. Since different spider species play different predating roles for a specific pest in its life cycle, it may be reliable to sustain the diversity of spider species within the specific area. These habit diversifications portray them as efficient predators the web weavers skewed towards phytophagous pests mainly from Diptera and Hymenoptera, whereas the non-web weavers foraged for foliage-dwelling pests such as Coleoptera and Homoptera. This is because spiders have the capacity to exist in various conditions, with wide-ranging food webs, and are able to exploit the various stages of their prey life cycles. Current trends in agriculture towards reduced pesticide use and ecological sustainability have led to surge of interest in spiders as potential biological control agents. The giant spider is a delicacy in some parts of South America-though its urticating hairs are carefully singed away before the spider is roasted in banana leaves.Biological control has come a long way towards adapting to the changing needs of agricultural pest suppression. A bite would sting about as much as a wasp’s. It's deadly to small creatures, but the Goliath’s venom is not lethal to humans. Though they don’t spin webs to trap food, Goliaths do use their weaving skills in another way: to line their burrows under the forest floor. ![]() Hatchlings stay close to their mother until they fully mature at two to three years. The hairs connect with the would-be assailant’s eyes and skin, sending it scurrying.įemale Goliaths use those same urticating hairs to cover their large egg sacs, which hold between 50 and 150 eggs. The spider rubs its legs together, launching a shower of miniature missiles into the air. If a predator like a coati gets too close, the Goliath has an unusual weapon: harpoon-shaped hairs (called urticating hairs) tipped with stinging barbs. They rely instead on modified leg hairs, sensitive to vibration, to warn them of danger. Unlike jumping spiders, Goliath birdeaters have bad eyesight. Spiders can’t ingest solid material, so they first liquefy the prey’s insides, then suck it dry. The spider then drags the dying animal back to its burrow and begins the digestion process. When a Goliath pounces on a mouse, for example, its inch-long fangs act like hypodermic needles, pumping neurotoxins into the hapless prey. Goliaths prowl the Amazon in northern South America. Insects make up most of the Goliath diet, but frogs and rodents are on the menu too. “Birdeater” came from an 18th-century engraving that showed another kind of tarantula eating a hummingbird, which gave the entire Theraphosa genus the name birdeater. Goliaths don’t usually eat birds, but they are big enough to be able to-and occasionally they do. Weighing up to six ounces and with a leg span of nearly a foot, this tarantula is the largest arachnid on the planet. The Goliath birdeater is the king of spiders.
