摘　　要：Mass production of black soldier fly,Hermetia illucens(L.)(Diptera:Stra-tiomyidae),larvae results in massive heat generation,which impacts facility management,waste conversion,and larval production.We tested daily substrate temperatures with dif-ferent population densities(i.e.,0,500,1000,5000,and 10000 larvae/pan),different pop-ulation sizes(i.e.,166,1000,and 10000 larvae at a fixed feed ratio)and air temperatures(i.e.,20 and 30℃)on various production parameters.Impacts of shifting larvae from 30 to 20℃on either day 9 or 11 were also determined.Larval activity increased substrate tem-peratures significantly(i.e.,at least 10℃above air temperatures).Low air temperature favored growth with the higher population sizes while high temperature favored growth with low population sizes.The greatest average individual larval weights(e.g.,0.126 and 0.124 g)and feed conversion ratios(e.g.,1.92 and 2.08 g/g)were recorded for either 10000 larvae reared at 20℃or 100 larvae reared at 30 C.Shifting temperatures from high(30℃)to low(20℃)in between(~10-d-old larvae)impacted larval production weights(16%increases)and feed conversion ratios(increased 14%).Facilities should consider the impact of larval density,population size,and air temperature during black soldier fly mass production as these factors impact overall larval production.
