We found this yellow eggs on Mango leaf. It was found with larva of cabbage butterfly. when it was reared under rearing box, we found some parasitoid emerging out from this egg. And next time when we reared the larva of cabbage butterfly solely in a rearing box, we found that egg automatically on the box the next day(sorry for not having that image!!!) and after few days same thing emerged.. How could that be possible??? Please suggest..
These are parasitoids of the caterpillars of cabbage butterfly, please see the following link :

Oh My God... Really amazing.... I got my confusions clear. Many many thanks to Hanna M. Madanat sir and Navaraj Upadhyaya sir..
These are the cocoons of the parasitoids of the catterpillar of the cabbage butterfly, most likely a braconid wasp ( Cotesia glomerata)

Mr. Luis Miguel Constantino truly answered your question, these are the cocoons of the parasitoids of the catterpillar of the cabbage butterfly, most likely a braconid wasp
They are Braconid ectoparasitoids, so eggs you saw most probably are their coccon of pupae, therefore when you put larva of cabbage butterfly you might overlook parasitoid larva living on butterfly larva. This is all.
Dear Krishna
by the time of rearing, I'm sure you have same pictures
Pls. find the attached photo, Egg and adults of Cotesia golmerata from larvae of Pieris brassicae I rear them now
Hoping this will be helpful to your project, good luck

It is evident that what you call eggs were pupae of the parasitoid of the larva. When the larvae of the parasitoid finished their development inside their host they came out of the parasitized larva and pupated next to it. As far as the observation that the same occurred with another larva it is obvious that this larva was also parasitized by the parasitoid and upon completion of the larval development they exited their host and pupated.
Dear John
With the quick answer, I meant eggs parasite
Thanks for the correction
in my research I apply some insect viruses on different insect larvea

john was right with his submission. What you observed was phenomenon called hyper-parasitism. There are several egg and larval parasitoid of the cabbage butterfly.
