If bed bug eggs hatch in a vacant home, how long can the nymphs survive without a meal?
1st stage instar nymphs that have never fed after hatching will survive 6–8 weeks at room temperature. Temperature plays a big factor in the answer. The hotter it is, the quicker they will die.According to the BB Bible, 1st stage instar nymphs that HAVE FED ONCE after hatching can survive up to 275 days at a 50 degree temperature, 114 days at 65 degrees, 29 days at 81 degrees and only 17 days at 99 degrees.Other stages at the same four temperatures (50, 65, 81 and 99 degress Fahrenheit)2nd instar nymphs: 399, 171, 46 and 31 days3rd instar nymphs: 413, 215, 72 and 36 days4th instar nymphs: 433, 235, 74 and 38 days5th instar nymphs: 485, 162, 40 and 33 daysAdult Male: 402, 176, 44 and 29 daysAdult Female: 425, 277, 87 and 32 daysResource for getting rid of bed bugs - Breaking Bed Bugs
How long does it take for the eggs of a parasitic wasp to hatch?
It depends on multiple factors; most prominent of which are: A) The latitude at which you live, more temperate areas will have seasonal cycles and the wasp adults will only emerge when a new generation of Solanaceae feeding moths hatch. So that new hosts are immediately available to the adults wasps. B) The specific species of wasp; certain wasps will have single season lifespan (less prolific parasitoids) and others will have multi lifespan seasons to produce some of the most prolific biological control agents.
How long does it take for convict cichlid eggs to hatch?
Just got home from work and My cichlid finally laid her eggs!:) I have been researching a lot before they begain to breed, however I wanted to make sure I know everything I need to know before they hatch, and how long until the little guys hatch? thanks :)
How long does it take a praying mantis egg sack to hatch?
Depending on the species, the female then lays between 10 to 400 eggs. These are typically deposited in a frothy mass that is produced by glands in the abdomen. This froth then hardens, creating a protective capsule with a further protective coat, and the egg mass is called an ootheca. Depending on the species these can be attached to a flat surface, wrapped around a plant or even deposited in the ground. In spite of the versatility and durability of the eggs, they are often preyed on, especially by several species of parasitic wasps. In a few species, the mother guards the eggs. they take about 5 months to hatch.
Can Black Widow Spiders eggs hatch with out Mateing?
Please contact your state entomologist or a university in your area and have it verified. Make sure you have some way to verify that you discovered this phemonenom. Before you contact them send your self a letter stating you find. Don't open it you may need it later to get full credit for the find. You may have discovered another species that can give virgin birth. Bees do it all the time. Generally they can produce only male off spring without being fertilized.. One species the Cape bee can lay unfertilized eggs and by transferring some of her mitochondria to the egg can produce females that can be grown into queens. Recently a Komodo Dragon laid eggs that hatched into male offspring. It caused quite a stir in the Scientific circles. With these incidents to draw on, I wouldn't be the least bit surprised if your black widow spider did the same thing. I would guess the babies are all males? If not they, like the cape bees have a great survival strategy in place. Look up "Pathenogenetically" and complete you quest.. Keep in mind that a queen bee mates only once, with up to twenty drones and then never again. She decides as she lays eggs for up to the next eight or more years if she will fertilize the egg from the preserved sperm to create workers or with hold it and produce drones. Maybe the Black widow has this same ability.
Is it true that some worker bees are able to lay eggs which hatch as drones if the queen dies?
No, they could not mate with a drone first and lay fertile eggs. Their reproductive organs have never fully developed.This is the abdomen of a queen bee:This is the abdomen of a worker bee:Notice how in the worker bee, the ovaries are shrunk almost to non-existence and the spermatheca (sperm storage organs, where the queen stores the sperm of the 10 - 40 drones she mates with) are so vestigial as to be almost non-existent. On the flip side, the sting sheath and the stinger are huge, and the shape of the digestive tract is very different.These differences take hold during larval development because the worker bee larvae get a drastically different diet, devoid of the “royal jelly” secretions from nurse bees that promote development of functional sex organs, and triggering a completely different epigenetic program then for a queen larva.Laying the unfertilized eggs that turn into drones is a last ditch effort of a hopelessly queenless colony to disperse some of its’ genetic material before dying out. Such “laying workers” usually arise when the hive has lost the queen, failed to raise another one, and now have no female larvae young enough (3.5 - 4.5 days old) to try again. Such a colony is destined to dwindle as the worker bees die off from old age. So, they raise drones that might mate with a virgin queen from a different colony, so that the worker bee’s genes might live on.
How does egg of worker bee evolve to queen bee in a bee hive?
The queen doesn't actually 'evolve' from a worker bee. Bees start out their lives as tiny litle white grubs called larvae. They look and act a like a maggot. After they have eaten enough they pupate, much like a catterpillar turning into a butterfly, and they emerge as adult bees with wings and legs. Queens and worker bees are both female. All female larvae, whether worker or drone hatch out of the egg identical in every respect. At first all larvae are fed a special highly nutirtious food called 'royal jelly' that is produced by the worker bees. After a few days the diet is changed over to a much less nutritious food that is basically just honey. When the hive needs a new queen, the workers select a larva at random and its diet doesn't change. It is fed on nothing but royal jelly until it is ready to pupate into an adult bee. That highly nutririous diet causes it to pupate into a quuen rather than a worker, and it emerges as a fully formed queen bee. Note that at no stage was the new queen a worker bee. Although you could say she existed as a worker larva for a few days. But worker bees don't evolve into queen bees. _____________________ Republican said: "A queen bee egg is specially made when a >>>>>>>>>> male be, a drone, fertilizes it." You know you really couldn't be more wrong even if you tried. Only male bees (drones) are the result of mating and fertilised eggs. Both workers and queens are the reuslt of unfertilised eggs. There is no embryological or genetic difference between a queen egg and a worker egg. After hatching all female larvae, whether worker or drone hatch out of the egg identical in every respect.
Special features about honey bees?
They are cold blooded but, can maintain a hive temperature of over 92 F even in 50 to 60 below zero all winter long by vibrating their bodies to produce heat by friction. They are the only insects that select their queens and raise them for that specific purpose which is laying eggs for the next generation. They lay eggs in the dead of winter and heat and hatch them for the spring honey harvest. By maintaining a constant temperature in the hive they can determine how long it takes for the eggs to hatch and develop into mature bees. They feed their babies and nurture them to adulthood and beyond. They produce honey by changing the molecular structure of the nectar they collect and then dry it to specification and seal it up to preserve it for future use. They can instruct the other bees where the nectar and pollen is located as far as 6 miles from the hive by their "waggle dance" The scout bees locate the sources of honey and worker bees select the nectar and pollen by choosing between samples that the scouts bring back to the hive. Bees also build the structures that hold the honey, the babies and pollen . I could go one for pages about the special features of bees, however, I feel this will suffice for a good start.
