In the 19th century, prominent physicians sought to establish the “physical peculiarities” of blacks that could “serve to distinguish him from the white man” (23).
Typically, masses of the overwintering adults are collected in Pacific Coast mountains and are then either distributed in crop areas or kept in captivity for the rest of winter and sold in spring.
Typical answers are: 1/2 pint per 1 small garden or 1/4 acre; or 1 quart per acre; or 30,000 ladybugs per 10 acres -- once again depending upon who you consult, there are 9,000 ladybugs per pint; 135,000 ladybugs per gallon; or 1,500 ladybugs per 1 ounce of weight.
Overall, the prey of ladybugs includes mites (5), spider mites (6), springtails (12), thrips (23), lace bugs (28), chinch bugs (32), leafhoppers (37), perhaps treehoppers (38), psyllids (40), whiteflies (41), aphids (42), gallmaking and/or woolly aphids (43), pine and/or spruce aphids (44), scale insects (46), mealybugs (47), such other ladybugs as the Mexican bean beetle (65) [one of the few plant-eating species of ladybugs], asparagus beetles (70), the Colorado potato beetle (72), perhaps flea beetles (73), the elm leaf beetle (82), weevils (83), perhaps the diamondback moth (105), leafrollers (112), the European corn borer (117), sphinx moths and/or hornworms (130), cutworms and/or related caterpillars (138), the corn earworm (139), the stalk borer (142), and webspinning and/or leafrolling sawflies (157).
Beneficial species of ladybugs have often been intentionally imported into areas plagued by insect pests.
The military covertly tested mustard gas and other chemicals on black soldiers during World War II, and the US Public Health Service, in collaboration with the Tuskegee Institute, studied the progression of untreated syphilis in black men from 1932 to 1972.
two short selections from "A Cyborg Manifesto" by Donna Haraway (link) "There are several consequences to taking seriously the imagery of cyborgs as other than our enemies.
To prevent ladybugs from flying away (as they often do, to burn-off excess winter fat after finally being released from hibernation and captivity), release ladybugs late in the afternoon or, better yet, at sundown: For 5 days keep the ladybugs in a 4' x 6' x 4'-high tightly screened cage in the release area and daily spray the plants inside with 1 pound of "wheast" (a high-protein byproduct of the cheese industry, available as "Formula 57") and 1 pound of sugar in 1 gallon of water (This mixture will also attract native ladybugs and lacewings, but perhaps also ants and, after the cage is removed, wasps and bees -- this extreme method should be tested first.).
This, of course, requires cooperation between neighbors or within garden clubs or other community organizations, whose members should all benefit from decreased pest control expenditures, especially in the long-run.
It is best to keep ladybugs hibernating in their container in the crisper compartment of the refrigerator (not the freezer) until there are enough pests out to keep the ladybugs well fed.Tags: Adult Dating, affair dating, sex dating
