Incredible males!

We often wonder whether BSF males 1) have less sperm production due to ageing and non-feeding stage; 2) if sperm production is related to the body size.

While all wonder might be wrong.

An article from University of Tours, France, has drawn us attention.

• The width (size) of the testis decreases over time in virgin black soldier fly males.
• Sperm are present immediately after emergence.
• Sperm counts increase in virgin males, at least until 20 days.
• Sperm counts is correlated with age, but not related to males body size.
• The minimum sperm count is 3125 for 0-day-old male
• The maximum count is 52183 for 20-day-old male

Thinking practically, aging males might have lower sperm quality, impacting offspring development.

Although the research doesn’t provide definitive answers, interestingly, industry data suggests that eggs collected on day 9 (post-emergence) have lower hatchability compared to those collected on day 4.

Let’s stay curious and keep exploring the fascinating world of insect dynamics! ?? #Entomology #ResearchUpdate
