| The antlion resources of Guiyang area was investigated and the dominant species was ascertained this thesis.The biology characteristics and artificial breeding technology of the dominant species were also studied in this thesis.The general reseach results are presented as follows:1.There are Myreleon formicarious Linnaeus,M.bimaculatus Yang,Euroleon coreaus Okamoto and E.polyspilus Gerstacker in Guiyang area,the dominant species is M.formicarious Linnaeus.2.The larva instar of M.formicarious Linnaeus was measured by head capsule width and mandiblulosuctorial length.First-instar's head capsule width range is 0.61～0.74mm,mandiblulosuctorial length range is 0.88～1.26mm;second-instar's head capsule width range is 1.03～1.67mm,mandiblulosuctofial length range is 1.33～2.33mm,third-instar's head capsule width range is 1.50～1.87mm,mandible-ulosuctorial length range is 2.30～2.73mm.3.The development periods of M.formicarious Linnaeus on 3 different feeds were compared.The times from larva to adulte is 116d,almost 4 monthes by feeding termite,feeding fly-larva is 88d,feeding Tenebrio molitor Linnaeus is 91d.Through analysis of variance,there was significant difference between feeding termite group and other groups,and there was no significant difference between feeding fly-larva and feeding tennbrio molitor.4.Lower or too higher temperature can delay development and survival rate in the range 15℃to 31℃.There were significant differences in various temperature. The larva development time is 128d in 15℃,it is more than two times as in 27℃.The development period delay to 75d in 31℃.So the suitable development temperature range of larva of M.formicarious Linnaeus is 23℃to 27℃.The most suitable temperature is 25℃.Under the same feeding condition,the second-and third-instar larva and pupa's survivor have no significant difference in 19℃,23℃and 27℃.5.Too long feeding interval can delay antlion development period.Under conditions of once feeding a day and once feeding every three days,the antlion have short development times and high survivor.Analysis of variance,there were no significant differences in the two feeding frequency.So the feeding frequency of once feeding a day or once feeding every three days is suitable for artificial Feeding.6.The larva of all three instars have higher rate of pit-building and pit diameter in sands(70～40 mesh).Along with increase in age,antlion can be tolerant to larger particles.The rate of constructed pits and pit-diameter have no statistically significant differences in sands(＞70 and＜20 mesh ).Mixed particles can increase the stability of pit,so mixed particles is suitable to artificial feeding.7.The larva of all three instars have higher rate of pit-building and no significant differences in water content(＜3%).The high water content can hinder antlion building-pit.When artificial feeding,the water content of sands should be≤2%.8.The utilization rate of fly larva is higher than Tenebrio molitor Linnaeus,and the highest utilization rate based on once feeding every three days.The food utilization rate of second-instar is higher than third-instar larva.So when artificial feeding,using myiasis as feed with once feeding every three days is the best.9.The suitable building-pit area for second-instar larva is 25 cm~2/per,third-instar larva is 40 cm~2/per.10.Adult can be feeded by non-live food.The compages way of ovarioles is 5+3+2.The female can most oviposit 200 eggs.
