Depending on the moisture content of the food scraps and the ambient humidity of the system, several liters of 'tea' are also produced as liquid effluent. After filtering through cheese cloth and dilution at a 10:1 or 15:1 ratio, this tea may be used as a liquid fertilizer or <span class="blsp-spelling-error" id="SPELLING_ERROR_4">foliar</span> spray. This effluent is also an extremely powerful attractant for adult <span class="blsp-spelling-error" id="SPELLING_ERROR_5">BSF</span> females, and will result in the <span class="blsp-spelling-error" id="SPELLING_ERROR_6">ovipositing</span> of eggs on any surface near the collection receptacle. With this in mind, tea from <span class="blsp-spelling-error" id="SPELLING_ERROR_7">BSF</span> systems may be used to start up additional units, by enticing gravid females to seed new piles of scraps. For every 100 lbs of scraps, roughly 5 lbs of a black, friable residue remain at the bottom of any <span class="blsp-spelling-error" id="SPELLING_ERROR_8">BSF</span> <span class="blsp-spelling-error" id="SPELLING_ERROR_9">bioconversion</span> system. This casting residue, along with undigested food remains and <span class="blsp-spelling-corrected" id="SPELLING_ERROR_10">shredded</span> chitin exoskeletons from <span class="blsp-spelling-error" id="SPELLING_ERROR_11">BSF</span> larvae, creates a mixture that is undergoes further decomposition by beneficial bacteria and fungi. This combo material may be used directly in <span class="blsp-spelling-error" id="SPELLING_ERROR_12">the</span> garden as a nutritious <span class="blsp-spelling-error" id="SPELLING_ERROR_13">soil</span> amendment, or fed to <span class="blsp-spelling-error" id="SPELLING_ERROR_14">redworms</span> for transformation into <span class="blsp-spelling-error" id="SPELLING_ERROR_15">vermiculture</span> castings.</div>Greeniehttp://www.blogger.com/profile/10056235855329962791noreply@blogger.com10tag:blogger.com,1999:blog-6388443284432604414.post-10135812757808774512007-08-06T10:35:00.000-04:002007-08-06T10:39:04.791-04:00BSF as Food for Home-Raised Chickens<div align="justify">Did you know that a healthy hen fed a balanced diet can lay fresh, wholesome eggs for up to 18 years? It is rewarding and a lot of fun to have a small hobby farm in the backyard. A home-made movable coop that confines and shelters your small flock is easy to build and takes up a lot less space than you may realize. Chickens love to scratch the dirt endlessly looking for tasty grubs and other insects. A few handfuls a day of <span class="blsp-spelling-error" id="SPELLING_ERROR_0">BSF</span> pupae scattered throughout the garden will provide hours of enjoyment for your friends and family. There is a multitude of excellent poultry rearing websites online that will give advice on coop construction and care. Please research the topic thoroughly before you begin. Just keep in mind that the structure should be well ventilated, have a built-in shaded area and provide a minimum of 3 square feet of space per bird. A constant supply of fresh water fortified with vitamins and <span class="blsp-spelling-error" id="SPELLING_ERROR_1">probiotics</span>, along with a balanced diet that includes <span class="blsp-spelling-error" id="SPELLING_ERROR_2">BSF</span> will help to product a happy, healthy, egg-laying flock. Please consult your local ordinances as they pertain to residential restrictions on bird rearing and poultry. </div>Greeniehttp://www.blogger.com/profile/10056235855329962791noreply@blogger.com1tag:blogger.com,1999:blog-6388443284432604414.post-10805775811634548962007-07-25T12:51:00.000-04:002007-07-25T12:56:48.922-04:00Not Associated With Disease Transmission<div align="justify">Unlike most other flies, BSF adults do not go into houses, they do not have functional mouth parts, they do not eat, they do not regurgitate on human food, and therefore, they are not associated in any way with the transmission of disease. Adults do not bite, bother or annoy humans. Their activity is limited solely to mating and egg-laying. Note that it is only the females that visit waste, not the males, since males do not lay eggs. When females visit waste to lay eggs, they never actually come into contact with the the waste. They lay their eggs above or to the side, never on, otherwise they run the risk of their eggs being eaten along with the waste. </div>Greeniehttp://www.blogger.com/profile/10056235855329962791noreply@blogger.com7tag:blogger.com,1999:blog-6388443284432604414.post-62697077924232706462007-07-25T12:41:00.000-04:002007-09-25T15:37:21.499-04:00Life Cycle At A Glance<div align="justify">A female produces about 900 eggs in her short life of 5 to 8 days. Housefly adults, <strong>by contrast</strong>, live up to 30 days, and during this long period, they must eat, and in so doing, they are actively engaged in the spread of disease. Their naturally short life span is the reason why they are not vectors of human pathogens. <span class="blsp-spelling-error" id="SPELLING_ERROR_0">BSF</span> eggs are relatively slow in hatching: from 102 to 105 hours. The newly hatched larvae have a light cream color, and crawl onto the waste, where they begin to consume it with amazing speed. Under ideal conditions, it takes about two weeks for the larvae to reach maturity. If the temperature is not right, or if there is not enough food, this period of two weeks may extend to several months. The ability of the <span class="blsp-spelling-error" id="SPELLING_ERROR_1">BSF</span> larva to extend its life cycle under conditions of stress is a very important reason why it may be used for waste disposal processing. <span class="blsp-spelling-error" id="SPELLING_ERROR_2">BSF</span> larvae pass through five stages or <span class="blsp-spelling-error" id="SPELLING_ERROR_3">instars</span>. Upon reaching maturity, they are about 25 mm in length, 6 mm in diameter, and they weigh about 0.2 grams. The dormant puparium is dark brown to charcoal gray in color. These larvae and pupae are extremely tough and robust. They can survive under conditions of extreme oxygen deprivation. </div>Greeniehttp://www.blogger.com/profile/10056235855329962791noreply@blogger.com17tag:blogger.com,1999:blog-6388443284432604414.post-18369099352168640272007-07-20T10:23:00.000-04:002007-07-20T10:28:46.186-04:00Attracting Songbirds<div align="justify">Mature larvae are an ideal food for attracting bluebirds, orioles, cardinals, goldfinches, thrushes, catbirds, woodpeckers, <span class="blsp-spelling-error" id="SPELLING_ERROR_0">nuthatchers</span>, chickadees, and warblers to the back yard garden. The logical and most common means of offering this nutritious food is to use a special bluebird feeder, or similar unit that has been designed to distribute <span class="blsp-spelling-error" id="SPELLING_ERROR_1">mealworms</span> to birds. Look for units that possess a sloped, overhanging lid or roof which will prevent runoff of rain or dew into the feeding area. Drainage holes and critter guards are also beneficial to a functional feeder.</div>Greeniehttp://www.blogger.com/profile/10056235855329962791noreply@blogger.com0tag:blogger.com,1999:blog-6388443284432604414.post-37018037894386435152007-07-19T13:27:00.000-04:002007-07-19T13:54:00.580-04:00Residential Food Waste Diversion<div align="justify">BSF larvae are voracious consumers of food scraps. Decomposition via digestion can be measured in hours, rather than weeks or months. Wastes are reduced by up to 95% of original weight and volume. Despite their insatiable appetite in the larval stage, BSF are a relatively innocuous species of native arthropod - harmless to humans, pets and wildlife. Adult BSF possess no functional mouth parts or stingers, so they are not capable of feeding, biting, or inflicting pain. They are notable at mitigating the presence of the common house fly and other filth bearing flies - a definite plus for back yard composting.</div>Greeniehttp://www.blogger.com/profile/10056235855329962791noreply@blogger.com0tag:blogger.com,1999:blog-6388443284432604414.post-12260450578154885152007-07-19T13:22:00.000-04:002007-07-19T13:24:20.268-04:00Benefits to Vermiculture<div align="justify">One of the drawbacks of raising <strong><span style="color:#990000;">redworms</span></strong> is the speed at which food scraps are processed into castings. Before the worms can begin their feast, it is necessary for the beneficial micro-organisms to begin breaking down the scraps - <span style="color:#990000;"><strong>redworms</strong></span> do not eat fresh foods, only ones that are decomposing. This can take a great deal of time, especially on new setups. The surface to volume ratio is also a factor that affects the rate of digestion. The smaller the particle size, the faster the decomposition. Most organic kitchen waste is not ground up sufficiently to maximize decay, and thus the transformation into casting can be painfully slow. </div><br /><div align="justify">BSF larvae are notably different that <span style="color:#990000;"><strong>redworms</strong></span> because they will actively consume fresh scraps immediately, without the need for pre-decomposition. BSF digestion is focused on the proteins and fats in the waste pile - most of the cellulosic materials do not get eaten by the larvae, though physical chopping into smaller pieces does occur. The remaining cellulose fraction is targeted quickly by fungi and composting bacteria at the lower levels of the pile. The black, friable residue that remains after digestion by the larvae is of ideal consistency, particle size and nutrient balance to be fed directly to an active vermiculture system. The end result of this two-tiered processing is the production of <span style="color:#990000;"><strong>redworm</strong></span> castings at a faster rate than using redworms alone.</div>Greeniehttp://www.blogger.com/profile/10056235855329962791noreply@blogger.com8tag:blogger.com,1999:blog-6388443284432604414.post-38234791482625382692007-07-18T23:00:00.000-04:002007-07-18T23:09:39.002-04:00Welcome!<div align="justify">Thank you for visiting this weblog about the Black Soldier Fly.
