Dlium Dumbcane (Dieffenbachia seguine)

Single leaf, seated alternately, oval shape, flat edge, blunt base, pointed tip, length 25-40 cm, width 15-20 cm, flattened, single bone in the middle and fiber-pinnate, smooth surface, overall green or spotted white and yellow spread in the middle.

Dumbcane emits a lot of water vapor which causes the air to become moist and diligently spraying phytochemical compounds to suppress bacterial populations and fungal spores as a mechanism for plants to survive and protect themselves from pathogens.

Blanceng grows well in high humidity and low intensity sunlight. The sap contains raphide as a calcium oxalate crystal which has a needle-like shape and is stored in an idioblast. The sap is toxic which causes itching, swelling, necrosis and destruction of blood vessels.

Cotton stainer bugs (Dysdercus)

Cotton stainer bug ( Dysdercus ) is a genus in Pyrrhocoridae, the imago and nymph phases have black and red colors, three pairs of limbs of the same length and differ only in the size of the limbs of each segment, the limbs on the femur are slightly larger than the tarsus and tibia. Dysdercus has a mouth consisting of a rostum and a stylet. The rostume is located on the anterior part of the head, is elongated and segmented as a wrapper for the stylet. This sucker is formed by the food tract and salivary tract. The nymphs undergo several molting processes to become imago. The species in Dysdercus consume plant fluids wherein the nymphs perform in groups, whereas the imago does more individually. They trample the stems of plants regularly and form long rows.
