Trichomes (hairs) are one of the most important morphological parameters of plant resistance to insect. The inheritance of trichomes in soybean leaflet and its resistance to armyworm was studied during 1997 at screencage and laboratory of soybean breeding of the RILET, Malang. Soybean genotypes of PI 229358 and Sodendaizu-N (dense type, tolerance to armyworm), Ichyou (glabrous type, susceptibl ...

The soybean armyworm, Spodoptera litura, is one of the major insect pests of soybean. Pest control of soybean at the present is usually done by spraying insecticides. Due to the environmental problems resulted from excessive use of insecticides, the role of sex pheromonoid as an integral part of the integrated pest management of soybean armyworm was studied. The results showed that sex pheromo ...

To date, chemical control remains the most common way to reduce beet armyworm (Spodoptera exigua) populations. However, this insect has become more tolerant or resistant to many chemical insecticides and the insect larvae usually hide inside hollow, tube-like leaves of host plant so they were difficult to kill by spraying insecticides. The use of viral and bacterial insecticide to solve these ...

Vegetative development in maize can be divided into juvenile and adult phases. Each phase is characterized by distinctive morphology and physiology. Two maize hybrids with resistance to fall armyworm feeding, two susceptible hybrids, and a hybrid with an intermediate level of resistance were evaluated for the timing of juvenile-adult phase transition and duration of transition period. The fall ...
