Trap cropping is a promising, environmentally sound approach to manage pests in agricultural and forest systems through exploiting insect preferences for certain host plants. In a wide range of cropping systems, trap cropping greatly reduces damage, disease and insecticide use on the main crops, and thus increases the yield of the main crop. In a …

Research says compared with maize monocropping, intercropping with legumes, Phaseolus vulgaris L. var. Roscoco can reduce the larval population by enhancing mortality rate. Underlying mechanisms are antixenosis and antibiosis effects along with trichome-based plant defence mechanisms. In the push-pull system, planting Silverleaf desmodium, Desmodium uncinatum as intercrop “push crop” can repel FAW moth because of …

Research Notes
Two potential cover crops such as cowpea and sunnhemp have the potential to reduce the larval population of #fallarmyworm by lengthening the developmental time and increasing larval mortality. The other cover crops such as either corn or sorghum-sudangrass are two more preferred crops for the fall armyworm. Hence there is a potential to design a …

For the successful #fallarmyworm management in maize crop, various intervention approaches should be adopted in integrated ways. Adopting a single pest management approach may not be able to keep the pest below the economic threshold level. Hence the integration of various approaches at a time or on a regular basis is suggested for the successful …

Maintaining crop and non-crop diversity from field to landscape-level are more useful for the natural enemies and improve conservation biological control by increasing their fitness. These measures which are popular in our communities are crop rotation, intercropping, mix-cropping, maintaining diverse field margins with many flowering and non-flowering plants, increasing the forest diversity at a landscape …

Cultural method of pest management integrates a number of local and agro-ecological practices to reduce the pest populations. Manual destruction of egg masses and larval population, fertilizers and irrigation management to make a healthy plant, field sanitation, use of resistant varieties, adjustment in planting time etc. are some examples of cultural practices. In case of …

Habitat manipulation in the form of cover crops, intercrops, maintaining flower strips in the main field increases the activity and ‘fitness’ of pest natural enemies and thereby minimize pest pressure in agriculture (natural enemies hypothesis). In another side, the probability of finding a host in diversified crops is reduced in the diversified field (resource concentration). …

Cultural method of pest control make a less favourable environment to the pest and make a more favourable for their natural enemies. This method is the most widely adopted approaches in integrated pest management. As a part of cultural control, spraying sugar solution (10-20%) increases the population of certain parasitoids such as Campoletis flavicincta (Hymenoptera:Ichneumonidae), …
