To overcome the problems in rearing the teak defoliator, Hyblaea puera on artificial diet in a two-piece rearing tube for HpNPV mass multiplication, a new three-piece tube was designed and evaluated. The two-piece tube (Tube A) consists of two parts - a cylindrical main body with one end open (55mm x 23mm) and a perforated cap. The three-piece tube (Tube B) consists of a main body with both ends open (55mm % 23mm), a diet cup (20mm % 22mm) and a perforated cap. Comparative evaluation of two types of tubes (main body of Tube A vs Diet cup of Tube B) was made in terms of their virus capture efficiency during inoculation and also easiness in diet dispensing and general handling. The short length of the diet cup of tube B favored highest virus capturing (added 30%) and efficient diet dispensing. Tube B could be an excellent option for rearing H. puera larvae for NPV mass production and laboratory culture maintenance and also for rearing of other lepidopteran larvae of similar behavior and size.Keywords

The economics of mass production of the nucleopolyhedrovirus of the teak defoliator, Hyblaea puera Cramer (Lepidoptera: Hyblaeidae) (HpNPV) using the laboratory-reared and field-collected (from teak plantations) host larvae was compared. The data were based on 7645 laboratory-reared (LR) larvae and 8925 field-collected (FC) larvae. The virus production was carried out using fifth instar larva inoculated with 1x106 OBs (Viral Occlusion Bodies)/larva. The virus yield/larva in LR and FC larvae was 4.8x108 and 3.6x108 OBs, respectively. The virus productivity ratio in LR and FC larvae was 241 ± 55 and 178 ± 100.85 OBs, respectively. The cost of production of HpNPV per larva was higher in the case of LR (Rs. 0.82/larva) in comparison with FC (Rs.0.72). However, the cost of HpNPV required for spraying in one hectare at the rate of 1.63 x 1011 OBs worked out to be Rs. 279 and Rs. 317 in the case of LR and FC, respectively. A marginal difference in the virus yield was found affecting the cost of the virus produced.Keywords

The nucleopolyhedrovirus of the teak defoliator, Hyblaea puera Cramer (Lepidoptera: Hyblaeidae) (HpNPV) is a potential biocontrol agent of the pest. This paper describes a method to mass multiply HpNPV in situ in the field population of H. puera. The method is based on application of the virus suspension on young teak plantation infested with H. puera. An average yield of 4.8816 x 10& Polyhedral Occlusion Bodies (POBs) per fifth instar larva was obtained with this method. The advantage of this method of HpNPV production is that it is less expensive as it does not depend on host larval culture maintained in the laboratory.Keywords

In the year 1993, a 100 tree plot in a 17 year old teak plantation at Nilambur in Kerala was experimentally protected from Hyblaea puera Cramer, a serious defoliator of teak plantations, using a naturally occurring baculovirus (HpNPV) reported earlier from this pecies. During the year, there were four major peaks of defoliator infestation from March to June. One-time foliar application of a crude preparation of HpNPV at the rate of 1x105 POB/ml of the spray fluid, at the earliest sign of each infestation, gave 70-76 per cent protection of foliage during the first two infestations. A reduced foliage protection of 33-43 per cent obtained during the third and fourth infestations was attributable to occurrence of rain soon after application of the spray. In protected trees, the basal area increment was enhanced by 41 per cent, indicating the efficacy of HpNPV as a biocontrol agent against the teak defoliator.Keywords

The defoliation caused by Hyblaea puera can result in approximately 44% reduction in the annual volume increment of teak, a major timber tree. Several management options used in the past to control the pest were not effective due to high cost and environmental problems. In the present study we have used the vertical transmission characteristics of Hyblaea puera nucleopolyhedrovirus (HpNPV) for cost-effective and environment-friendly control of the most devastating pest. First, a laboratory experiment was conducted to verify the vertical transmission of HpNPV and later field spraying was done to study the effect under natural conditions. Vertical transmission of HpNPV in the laboratory ranged between 13% and 59%. The sublethal transmission caused reduction in pupation, adult emergence, male and female longevity, egg-laying period, fecundity, hatching of F1 eggs, F1 mortality, F1 pupation and F1 fecundity, but had no influence on the F2 survival compared to the control. Spraying of HpNPV in the epicentre population of the pest resulted a viral epizootic at the F2 generation and led to collapse of the host population. Seeding of HpNPV in the epicentre populations of the teak defoliator has been proved to be an economical and environment-friendly method for management of the pest.Keywords

In baculovirus–insect systems, a mixed-mode transmission strategy involving vertical transmission of virus from parent to offspring, and horizontal transmission from infected to susceptible or from the environment is well known. In this study, we examined the role of soil and excreta as alternative routes of horizontal transmission of Hyblaea puera nucleopolyhedrovirus (HpNPV) in the teak defoliator H. puera and how larval crowding influences these processes. The laboratory experiment failed to identify horizontal transmission of the virus from the soil during pupation or eclosion. However, the role of soil as a reservoir cannot be ignored as chances of transport of viral particles from soil to tree bark are expected through termite nests built on teak stems, which needs further examination. On the other hand, the experiments proved excreta as a major route of horizontal transmission and the rate of infectivity during crowding of larvae was significantly higher. Further research on other routes of horizontal transmission and host behaviour influencing the same are discussed here in the context of their role in managing of teak defoliator outbreaksKeywords
