Nesting biology of Anterhynchium fllavomarginatum Smith(Hymenoptera:Eumenidae)
The nesting biology of Anterhynchium flavomarginatum Smith,a predatory natural enemy in the southern forest region of China,was studied by using the trap nesting method,in order to better protect and utilize the biological control effect of the wasp on agricultural and forestry pests.From April 2021 to December 2022,five typical sample sites were selected in Jiangxi Province to place artificial nests to collect A.flavomarginatum,and the data related to the activity of the female adults of the wasp were observed and recorded in the field.The nest of the wasp was observed through indoor dissection of the nest tube and the data related to the nest structure were measured.The study found that A.flavomarginatum preferred to nest in the nest box with the mouth toward the southeast.The internal structure of the trap-nest consists of Vestibular cell,Brood cell,and Empty space.Relevant parameters of the internal structure of the trap-nest and the nesting behavior of female wasp were also observed and recorded,including the length and inner diameter of the trap-nest,as well as the number and length of Vestibular cell,Brood cell,and Empty space.The nesting behavior mainly includes the daily average number of nesting times,single predation time,mud collection time,time for handling prey,and nesting time.May,July and October were the most active periods for A.flavomarginatum nesting.There was no significant difference in the nesting habits of A.flavomarginatum among different individuals,but there were differences in the development of male and female offspring in different nest structures.Female adults were larger than males and need more food in their larval stage.The wasp may decide the sex distribution of its offspring according to the size of the insect chamber and the amount of food stored.
