Despite the defensive behavior, Africanized honey bees produce honey at higher rates than European bees in tropical climates and are commercially valuable.

Ambrosia beetles practice AGRICULTURE — they carry symbiotic fungus in body pouches, plant it in tree galleries, and eat the fungus as their sole food.

Females carry fungal spores in specialized body pouches called MYCANGIA — typically located in the head, prothorax, or near the mandibles.

Beetle agriculture independently evolved approximately 60 million years ago — predating human agriculture by 60 million years.

There are about 3,500 species of ambrosia beetle worldwide — among the few animals known to practice true agriculture.

Xylosandrus crassiusculus is a destructive invasive that kills nursery, orchard, and ornamental trees across the southern US.

Asian needle ant sting is rated 1.7 on the Schmidt Pain Index — comparable to a yellowjacket and significantly more painful than most ant stings.

Unlike most ant stings, Asian needle ant venom has caused documented severe allergic reactions including anaphylaxis in sensitized individuals.

She was first detected in Decatur, Georgia in 1932 in a shipment of cotton — but only exploded in abundance and range in the 2000s.

She displaces native Aphaenogaster ants — disrupting the seed-dispersal ecology of bloodroot, trilliums, and other spring wildflowers.

Range has expanded from Florida to New York since the 2000s — one of the most-monitored invasive ants by USDA APHIS in the 2020s.

The boll weevil crossed from Mexico into Texas in 1892 — and devastated US cotton agriculture for the next 75 years.

Cumulative US economic damage from boll weevil from 1892 through eradication is estimated at $22 billion in 2010 dollars.

Enterprise, Alabama erected a STATUE to the boll weevil in 1919 — for forcing crop diversification that enriched the area.

Boll weevil destruction of cotton accelerated the Great Migration of African Americans from the rural South to northern industrial cities.

The federal Boll Weevil Eradication Program (1978-2010) successfully eliminated the species from the US cotton belt — one of the most successful pest eradications in history.

The jewel wasp delivers a precise sting directly into the cockroach's BRAIN — into the central complex cells that control voluntary movement.

The cockroach retains sensory perception and muscle function — but can no longer initiate movement on her own. She becomes a true 'zombie.'

The wasp grabs the zombified cockroach by the antenna and LEADS her — walking on her own legs — into the wasp's burrow.

The wasp larva eats the still-living, still-helpless cockroach over 8 days — saving vital organs for last so the prey remains fresh.

Ram Gal and Frederic Libersat's neuroanatomical research on the jewel wasp's second sting is a flagship study in modern neuroethology.

European fire ant has been a major invasive in Metro Vancouver since the late 2000s — reshaping local landscaping and outdoor recreation.

Sting is sharp and burning — comparable to the imported red fire ant for pain intensity per sting.

Documented severe allergic reactions including anaphylaxis have occurred in sensitized individuals.

Colonies form massive interconnected supercolonies that exclude virtually all other small soil arthropods from infested ground.

Native to Europe but accidentally introduced to North America in the early 1900s in shipped horticultural plants — populations exploded only in the 2000s.

The Mexican bean beetle is one of the few VEGETARIAN ladybeetles — most Coccinellidae are aphid predators.

Adults and larvae scrape soft tissue from the underside of bean leaves — leaving the characteristic 'skeletonized' lace pattern.

She superficially resembles the beneficial Asian lady beetle and other true ladybugs — making field identification important before taking action.

Major host crops include snap bean, lima bean, kidney bean, mung bean, soybean, and cowpea — major US bean crop pest.
