Winged female and wingless male. Blastophaga psenes is a wasp species in the genus Blastophaga. It pollinates the common fig Ficus carica and the closely related Ficus palmata. [3] These wasps breed in figs without the need for a colony or nest, and the adults live for only a few days or weeks. [4]
The female is about 22 mm long; the male is smaller and lacks a stinger. [2] Males can be less than half of a female in size if emerging from a smaller or a superparasitized host. [ 3 ] The species undergoes four larval stages, where the initial younger larvae can be seen as external hemolymph-feeders on the paralysed roach's leg, and the last ...
A TWAP strategy is often used to minimize a large order's impact on the market and result in price improvement. [2] High-volume traders use TWAP to execute their orders over a specific time, so they trade to keep the price close to that which reflects the true market price. TWAP orders are a strategy of executing trades evenly over a specified ...
Adult female wasps usually live 2–3 days; there are, on average, 21 days over the course of a year during which it would be possible for make the trip in 1–3 days on air currents. In addition, a female wasp could hitch a ride on an aircraft.

As opposed to meat, lower costs are required to care for and produce insects. [4] Faster growth and reproduction rates. Crickets mature rather quickly and are typically full-grown within 3 weeks to a month, [4] and an individual female can lay from 1,200 to 1,500 eggs in three to four weeks. Cattle, however, become adults at 2 years, and the ...
In Polistes exclamans, equal sex ratio is obtained when only 46.3% of investment is devoted to females as female wasps are 1.16 times larger than male wasps. [16] In a study done by Strassmann, it was found that sexual investment is female biased, especially during years of high predation and when nests are generally less successful. [ 16 ]
