| To understand the dominant population composition and dynamics of Sphingidae insects in Luohe,Henan province,the adult population in this area was systematically monitored using a light trap from 2014 to 2023. The results indicated that a total of 17 insect species belonging to four subfamilies,14 genus were captured using light traps in farmland. Among them,eight species belonged to Ambulicinae,including Clanis bilineata tsingtauica Mell, Marumba gaschkewitschii v Bremer et Grey, M. sperchius Menetres,Parum colligata Walker,Smerinthus planus Walker, Callambulyx tatarinovi Bremer et Gery,Oxyambulyx schauffel bergeri Bremer et Grey and O. ochracea Butler. three species were identified in each of the subfamilies of Acherontiinae,Choerocampinae,and Philampelinae,namely Herse convolvuli Linnaeus,Psilogramma menephron Cramer,Dolbina tancrei Staudinger,Theretra japonica Orza,T. clotho Drury,Pergesa elpenor lewisi Butler,Ampelophaga rubiginosa Bremer et Grey,Macroglossum stellatarum Linnaeus and Acosmeryx castanea Rothschild et Jordan. The first and last occurrence days of the overall population in Luohe were in mid-April and early November,respectively,with the trapping peak occurring from early July to early September. H. convolvuli,C.bilineata tsingtauica and T. japonica were considered as dominant species,and their light-trapped regularity of the three were different. The first and last occurrences of H. convolvuli were from middle May to early June and from late September to mid October respectively. The first and last occurrences of T. japonica were from middle April to late May and in September respectively,Compared with the other species,C. bilineata tsingtauica had a later first occurrence and earlier last occurrence,appearing from late May to mid June and from early and mid September,respectively. The peak period of light lure for H. convolvuli was from late July to early September,the peak period of light lure for T. japonica was from late July to mid September,and that for C. bilineata tsingtauica was in mid and late July. Meanwhile,the peak occurrence date of C. bilineata tsingtauica was earlier and more concentrated than that of the other species. |
