TT No. 134: Parator VI.0 – A diagnostic tool for the identification of parasitoids and predators for bagworms and nettle caterpillars in oil palm

Parasitoids and predators play a major role in regulating pest numbers, especially the bagworms and nettle caterpillars. A field study had revealed the importance of several species of parasitoids in regulating the bagworm numbers at low levels, which in effect is natural control (Basri et al., 1995).

TT No. 133: Bacillus thuringiensis, MPOB SRBT1 for controlling Metisa plana (Lepidoptera:Psychidae)

Bacillus thuringiensis (Bt) is a rod-shaped 1-1.2 microns, gram positive, facultative anaerobic, spore forming bacterium. During sporulation, it produces insecticidal crystal proteins (ICP) or δ-endotoxins or Cry proteins. The primary insecticidal activity of Bt is due to the ICP. The Cry proteins were grouped according to their specific toxicity towards certain insect orders. Main Researcher: … Read more

TT No. 132: Cassia cobanensis as beneficial plant for bagworm control

Bagworm (Metisa plana) is one of the important leaf-eating pests of oil palm in Malaysia. Crop losses, due to the defoliation by a serious bagworm attack is inevitable. A moderate to serious bagworm defoliation may cause between 33%-47% reduction in yield (Wood et al., 1973; Basri, 1993). Main Researcher: Dr Mohd Basri Wahid

TT No. 130: Indirect method for measuring oil palm leaf area index

One of the important parameters in crop growth is leaf area index (LAI). It represents the leafiness of the crop as measured by the ratio of leaf to ground surface area. This index is often used in radiation conversion efficiency models, and in modelling photosynthetic response of the canopy to incident light (Dufrene et al., … Read more
