Project Title :Biology and Control measures of Diacrisia obliqua (Arctiidae-Lepidoptera) - Biology of Diacrisia obliqua.
Personnel : Narasimhanna MN, Kariappa BK
Project Period :1974-1975
Objectives :To study the life cycle of Diacrisia obliqua.
Results/Recommendations :The life cycle of the insect is completed in 48 days with a larval duration of 30 days.
· Egg: A single female moth lays about 1000-1200 eggs on the undersurface of leaf and the eggs are green and lustrous. Incubation period lasts for 4-6 days.
· Larva: The insect takes 7 instars to complete the larval stage and the larval duration is 30 days.
· Pupa: Pupa is formed inside a thin silken cocoon formed by the interwoven shed hairs of the caterpillar. The pupation takes place in the top layer of the soil or on the dried leaf surface. Pupa is dark brown in colour. At the end of 12-14 days moths emerged out.
· Imago: The body is brown in colour except the abdomen, which is brick red in colour. Wings have scattered black spots. Egg laying begins 48 hrs. after emergence.

Personnel :Narasimhanna MN, Kariappa BK
Project Period :1974-1975
Objectives :To study the efficacy of DDVP against the caterpillars of Diacrisia obliqua
Results/Recommendations :

Personnel :Narasimhanna MN, Kariappa BK
Project Period :1974-1976
Results/Recommendations :It is possible to use BHC 50% wp on hopper and adult stages safely as it does not harm silkworm after a week. It is acting both as contact and stomach poison. Though Ekalux and Endrin are found to be effective they can not be used on mulberry as the toxic residues remain on the leaves for a very long time.
Of the many chemical sprayed DDVP of 0.1% concentration can be effectively used against the caterpillars of Diacrisia obliqua and the leaves can be used for feeding silkworms after 5 days of spraying.

Results/Recommendations :It is observed that Rogor is very effective against jassid attack on mulberry. Experiments conducted have also confirmed that leaves sprayed with Rogor can be fed to silkworms after 12 days of spraying without any lethality.
Rogor of concentration 0.1% can be sprayed on the mulberry plants affected with jassids and leaves can be used for rearing silkworms after 15 days of spraying in irrigated condition whenever there is the attack of jassids spraying of Rogor is effective after 25 days of pruning in row system as the jassids are found to live on the nearby weeds and other plantations.

Personnel :Narasimhanna MN, Kariappa BK
Project Period :1975-1977
Objectives :To study in detail the bionomics of grasshopper.
Results/Recommendations :The female grasshopper lays the eggs at a depth of 2-3 cms in the loose soil. The minimum and maximum egg pod laid by a female is 6-18 and the number of eggs in each egg pod is 7-18.

It is yellowish brown in colour and the body weight is 3.04 mg. whereas the body colour of the 6th stage hopper is green and the red marking in the pronotum becomes very clear. The female weighs 118.5 mg whereas male weighs 58.50 mg.
Adult: The adult hopper resembles 6th stage except for the growth. The average body weight of the female is 205 mg. whereas male is 91 mg. The longevity of the adult varies from 1½ month to 2½ months. On the whole, the total life cycle of this grasshopper varies from 5 to 6 months.

Similarly, the progeny production was maximum at 25°C (242) which declined significantly (P<0.05) at other temperatures, being least at 30°C (96.6). No progeny production was observed at temperatures below 15°C and above 30°C.

Project Title :Management of pests of mulberry-Residual toxicity of insecticides against Cryptolaemus montrouzieri/Determination of waiting periods of commonly available insecticides against Cryptolaemus montrouzieri.
Personnel :Ram Kishore, Vinod Kumar, Pradip Kumar
Project Period :1990-1994
Objectives :Residual toxicity of 6 insecticides commonly used for the management of the pests of mulberry was assessed by calculating the median lethal time (LT-50) in days against the adults of Cryptolaemus montrouzieri.
Waiting periods of 12 commonly used insecticides for the management of the pests of mulberry were determined by bioassay method against the adults of Cryptolaemus montrouzieri, an efficient mealy bug predator.
Results/Recommendations :
The results indicate that Dichlorvos 0.2% is non-toxic to Cryptolaemus montrouzieri while the residual toxicity of other insecticides based on LT-50 is as follows:
Endosulfan-0.5%>Quinalphos-0.01%>Fenvalerate-0.01%>BHC-0.5%>Methyl Parathion-0.1%.
The results have, therefore clearly demonstrated that Nuvan (0.2%) can be used as a target-oriented insecticide for the management of the pests of mulberry.

Personnel :Ram Kishore, Manjunath D, Sathyaprasad K , Katiyar RL, Vinod Kumar A
Project Period :1990-1994
Objectives : The incidence of the pests of mulberry was monitored in the mulberry plots of CSR&TI, Mysore.
Results/Recommendations :Survey was undertaken every month in the mulberry garden of Karnataka, Andhra Pradesh and Tamil Nadu to identify a suitable natural enemy for important pest of mulberry which can be used unilaterally (biocontrol) or in combination with other control measures. In predators (Coleoptera) 9 predators (Hymenoptera) and pathogens were recovered.
The incidence of the pests, of mulberry (Sap suckers and leaf eaters) was mentioned in the mulberry plots of CSRTI, Mysore.
· Sap Suckers: Among the sap suckers namely mealy bug, thrips, jassids and scale insect, the average incidence of thrips was highest (42.55%) followed by mealy bug (20.89%) and jassid (20.28%).
· The occurrence was least in respect of scale insect (1.65%). The population of sap suckers did not vary significantly between summer (23.34%) and rainy (24.0%) seasons but it was significantly low during winter (16.68%).
· Leaf eaters: The average incidence of Bihar hairy caterpillar and wingless grasshopper was 10.20 and 2.66% respectively. The incidence of leaf eaters was significantly higher in rainy (7.55%) and winter (11.37%) seasons as compared to summer (0.36%).

Objectives :To study the attraction response of the uzifly, Exorista bombycis towards mulberry leaf (tender, medium & coarse), silkworm larvae and its excreta.
Results/Recommendations :On an average 81.7% silkworm larvae were found infested by uzifly in the presence of mulberry leaf as compared to 10.3% uzi infestation in the absence of mulberry leaf in rearing trays. The results clearly demonstrated that mulberry leaf plays a significant role in orienting uzifly towards silkworm for oviposition.

Objectives :Certain iodine containing liquid formulations like iodophore, tincture of iodine etc. were found effective in trapping the adult uzifly. Because of their unstable nature, highly stable formulation devoid of iodine compound was developed in the form of tablet using indigenously available low cost chemicals.
Results/Recommendations :One tablet is dissolved in one litre of water and the solution taken in light coloured containers is placed near the windows/doors for trapping the adult uziflies. Laboratory tests indicated that 90-100% of the flies released in the room were trapped and killed within 24 hr irrespective of the sex. The large scale field trials were initiated in 11 villages covering 29 silkworm crops (4395 layings). A total of 209 flies were trapped and killed within maximum of 30 flies in a crop.

Objectives :
· To find the biology of Nesolynx thymus on the pupae of Musca domestica.

· To record the parasitization potential of Nesolynx thymus cultured on house fly against uzi pupae.
· To assess the possibilities of mass production of Nesolynx thymus on pupae of Musca domestica.
Results/Recommendations :
· Nesolynx thymus completes its life cycle in 17.48±0.12 days (at 23-26°C) on pupae of the house fly Musca domestica. The parasitoid prefers younger pupae (1-2 days old) of Musca domestica to older ones (3-4 days old) for parasitisation. Nesolynx thymus emerging from the pupae of Musca domestica shows the parasitisation potential against the pupae of Exorista bombycis..

Objectives :To understand the factors influencing the pupation and diapause nature in Diaphania pulverulentalis.
Results/Recommendations :During pupation the final instar larva secretes silken thread and by which it falls down from the plant. Pupation takes place in the superficial layer of the soil under the soil lumps and crevices. It was observed that pupation mainly takes place in moisturized soil rather than dry soil. The distance between the pupation site and main plant was measured as 3-18 cm from the bottom of the plant during the preliminary study conducted in glasshouse.
