Rearing of Oleander Hawk Moth

This powerpoint presentation is about the methodology and observation of rearing of Oleander Hawk Moth. The rearing was done in IAAS, Paklihawa Campus

1. Rearing of Oleander Hawk Moth Prepared by Roll no. 19-24 B.Sc.Ag . 6 th Semester IAAS, Paklihawa Campus

2. Why Rear Insects? Rear to learn Rear for fun

3. Selection of Site Location : Narayani Boys Hostel, Paklihawa Campus Host Plant : Chameli ( Tabarnaemontana divarieta )

4. Oleander Hawk Moth

5. Introduction The oleander hawk-moth is a large insect with a wingspan of up to 12 cms . The oleander hawk-moth is named after one of its main food plants, oleander, on which its caterpillars feed. The plants on which the oleander hawk-moth caterpillar feeds contain toxins which may help protect the caterpillar against predators. The oleander hawk-moth’s attractive coloration helps to camouflage it against vegetation.

6. Insect Classification Kingdom : Animalia Phyllum : Arthopoda Class : Insecta Order : Lepidoptera Family : Spingidae Genus : Daphnis Species : D. nerii

7. Insect Capture & Rearing Box Insect was captured at egg stage. The leaves of the plant was plucked along with the egg to facilitate the natural condition. Rearing box was prepared so as to maintain the natural living state for the insect through artificial means.

8. E gg 2073/12/05 Green, oval eggs are laid singly on the upper leaf surface

9. 1 st Instar Larva Yellow colored with black elongated horn on the rear of the body.

10. 3 rd Instar Larva Blue-and-white eyespot near the head Y ellow horn on the rear. White bands along the side of the body. Small white and bluish dots scattered alongside the white bands.

11. 4 th Instar Larva

12. Pre-Fifth Instar As the larva becomes older, gradual browning of skin color distinctly observed.

13. 5 th Instar Larva

14. Initiation of Pupation Just before it pupates, the oleander hawk moth larva becomes browner in color .

15. Pupal Characteristics Pupa of the moth is light brown or pale reddish and has a wax-like appearance. Black spots and a black line are present down the middle. Under natural conditions, pupation occurs on the soil, under moss or dry leaves.

17. Adult Characteristics Head : Greenish head Thorax is green and the collar outlined in grey. There is triangular grey patch on the vertex. Abdomen is Pale greenish with oblique lines at the side, paired dark green lateral blotches on penultimate and a single dorsal blotch on ultimate segment.

19. Life Cycle Overview

20. Observations Changes in morphology of the insects with increase in age and the period of various stages of the insects were observed . Stages of Life Cycle Duration Egg 7 days Larva 14 days Pupa 16 days Adult

21. Result Hence, we were successfully able to rear the Oleander Hawk Moth in duration of 37 days.

22. Precautions Insects should be collected with the feeding materials or leaves or parts of parts where they are found. Feeding material should be changed everyday and the rearing box should be cleaned regularly to avoid various other infection. The environment of the rearing box should be made maintained according to the living conditions of the insect.
