This should be an interesting post for most people. Looking out for artificial lighting for the BSF breeding has long been an effort in this industry, as an efficient light source can eliminate the variability caused by sunlight quality due to weather or seasonal changes, and thus secure a stable black soldier fly egg production. There are couple key studies in this field that I have to acknowledge for developing our final product of a high efficiency LED breeding lamp.
Tomberlin, J. K. and D. C. Sheppard (2002). "Factors influencing mating and oviposition of black soldier flies (Diptera: Stratiomyidae) in a colony." Journal of Entomological Science 37(4): 345-352.
--In this study the researchers mentioned they have tested 40-watt Sylvania Gro Lux light and 430-watt Pro Ultralight Light System, but neither of these lights had triggered mating nor unfertilized eggs were deposited, and by accessing direct sunlight successful mating was observed and fertilized eggs were collected. This suggested that sunlight are different than those two artificial lights and black soldier fly adults need direct sunlight for successful mating as well as for formation of fertilized eggs.
Zhang, J., et al. (2010). "An artificial light source influences mating and oviposition of black soldier flies, Hermetia illucens." Journal of Insect Science 10(202).
--The researchers in this studies tested a few dozen light sources and found quartz iodine lamp is working for the black soldier fly, at 60% efficiency compared to sunlight. The study suggested a wavelength range from 450-700nm is responsible for successful mating of black soldier fly adults. However hatching rate was not investigated in this study.
Oonincx, D., et al. (2016). "Photoreceptor spectral sensitivity of the compound eyes of black soldier fly (Hermetia illucens) informing the design of LED-based illumination to enhance indoor reproduction." Journal of insect physiology 95: 133-139.
--Unlike the previous studies, this one took another approach to find the effective light. The researchers identified three types of photoreceptor cells in the compound eye of BSF, which can be excited by UV, blue color, and green color lights, respectively. A LED made with this color mixture were proven to be able to trigger black soldier fly mating and producing fertilized eggs, though the study did not give out a fertilization rate, but it did indicate the fertilization rate is higher than using fluorescent lamps, which is barely emitting any light at the UV range.
Nakamura, S., et al. (2016). "Small-scale rearing of the black soldier fly, Hermetia illucens (Diptera: Stratiomyidae), in the laboratory: low-cost and year-round rearing." Applied Entomology and Zoology 51(1): 161-166.
--In this study a system composite with two 40-watt fluorescent lamps supplemented with a 20-watt LED with spectrum from 400-800nm triggered mating in small cages (20x23x35cm) and fertilized eggs were obtained. When compared with flies bred under sunlight, the eggs produced under the LED system has lower fertilization rate.
The study from Zhang et al. (2010) had profound influence in the Chinese BSF breeding industry, as most breeding centers I visited had installed some quartz iodine lamps as light supplement. Though I did not see any breeding center had this lamp used as sole lighting source, as the main lighting source is still sunlight. The lights are only turned on when it's cloudy outside, or during the winter as this light emits huge amount of heat and can also be used as heating source. However this lamp has a big disadvantage and that is the energy consumption--as at least 500-watt is needed and usually people will use the 2000-watt version.
The EVO Consortium has long been looking for more efficient lighting sources, and there are indeed many lamps we found that works and we have observed couple key phenomenons:
So how to improve the lighting? Based on our researches there are basically two approaches to find better light sources.
First approach is testing hundreds of lights from the market and find the best one for our BSF. The advantage of this approach is that you can usually find a lamp that's very cheap and working, the quartz iodine lamps for example, usually cost under $10 USD per piece. On the other hand, the disadvantage of this approach is also very obvious, using the iodine lamps as example again, around 80% of the energy were used to generated useless lights which resulted in extremely high operating cost.
The second approach is to find out what lights does black soldier fly need for both mating stimulation and egg fertilization, then assemble the lights accordingly. The challenge of this approach is that we still know very little about how the light impact the black soldier fly physiology process that's responsible for mating success. Right now we only know what the black soldier fly compound eye can see, but potentially there are many more organisms that might be sensitive to the lights too, for example, the ocelli; the pigment cells on the body that make this insect black might be sensitive to the lights too, as we already know about human that even though we cannot see UV with our eyes, the UV helps us to produce substances such as vitamin D that's critical for our health.
Based on all the information obtained, we hypothesize that:
Above are the experience we wanted to share with you of what we know about the artificial light for breeding black soldier fly. With an overall consideration, we decided to use LED technology to assemble the best light possible as of today.

Nice article and very useful!

Send me A lamp Bulb that you believe would cause my Black Soldier Flies to mate Please send a price and availability also include Freight Thank You Larry Hays

The key is the temperature/humidity depending where you live 25 -28C. Then lighting the led full spectrum will work cost $50 Ebay. Oh yeah you get a lot of flys you get a lot of eggs. Third is the smelly substrate attracted. Add the signature scent to the get lot of eggs. Did you to it figured that out the black soldier fly larva pod scent?

Hi, the light (150W) is really good. After few minutes flyies goes wild. I am waiting now for fertilized eggs. Thanks!

Which kind of 150w globe did you use? Does it matter if the room is not very dark? (There is some light from the windows sometimes)?

Hi, I use 150W from Evo. The lengh od the wave is crucial. You can also experiment with bulba for reptils. I observe that day light in summer at 10-14 oclock (I live on Poland) is OK too (flies copulate and lay fertilised eggs) but no as good as Evo light.

You need to check Evo site. The 150 W lamps are good.

What an exquisite article! Your post is very helpful right now. Thank you for sharing this informative one.

I have read your post, it’s very informative and helpful too for readers. Thanks for sharing your knowledgeable content with us. I experienced 12v light bulbs for my home and in result, got appearance, safety and security. I recommend you to experience these <a href=”https://kingsoutdoorlighting.com/collections/outdoor-light-bulbs ”>12v light bulbs</a>.

Regarding what Peter William wrote, are you or anyone else using the 12v led bulbs for their black soldier flies? I looked at the link he posted at the bottom of his comment and saw the different colored MR16 12 V bulbs and was wondering if a lamp with a red, green, and blue bulb in a container for the BSFs would do the trick for helping them reproduce and fertilize the eggs. If so, this would seem to be the cheapest and most energy efficient way to go. Thanks for all who answer this question.

Some 12V LED works for a short period, as they have some unintended UV emitting at the beginning, but soon after this spectrum goes away the light will lost function for BSFL. This is a very common issue to many BSF lighting on the market.

Hi Evo, I am from India. Your product seems promising. How much is the cost for 200watts lamp. What is the minimum quantity order.
1/19/2023 12:54:58 am
Awesome read. very informative. I have tested over 10 types of lamps and each time got different results; none exceeded our expectations. I researched a lot and finally decided to order Evo Lights. Cause my main intention is to use LED lights solely as the light source. I will share the result when I get the lights in use.

I purchased one of your lights but I have flys but no eggs, any suggestions.
