Species of beetle
Propylea dissecta , is a species of lady beetle native to India, Sri Lanka, Bangladesh and Nepal.[ 1] [ 2]
Description
This robust beetle is about 5 to 6 mm in length. Elytra reddish orange in color with black central line. Adults show polymorphism with several intermediate and pale forms.[ 3]
Biology
Sexual maturity of male and female ladybirds is about 7 and 9 days respectively. Adult males are more willing to mate with females irrespective of age. Mating duration is longest amongst older adults where 30 day-old males and 20 day-old females can be found.[ 4] [ 5] Chemical signals as well as visual and tactile cues initiate male attraction toward females. Mating lasted longest about 275 minutes when it occurred between unmated individuals.[ 6]
It is a voracious predator on several aphids such as Aphis gossypii , Aphis craccivora , Lipaphis erysimi , Uroleucon compositae , Brevicoryne brassicae , Rhopalosiphum maidis and Myzus persicae .[ 7] [ 8] [ 9] [ 10]
