One of the pests that attacks oil palm plants is Oryctes rhinoceros Linn, known as a pest that borers oil palm shoots by sucking fluids and making holes in the midribs of leaves, stems and fruit. This horn beetle pest attacks oil palm plants planted in the field until they are 2.5 years old by destroying the growing point, resulting in damage to young leaves. So far, control has been carried out using chemical pesticides. The consequences of excessive use of pesticides can cause environmental problems. To avoid these consequences, natural horn beetle pest control is carried out using pineapple

Annotation:

AbstractNitidulid beetles of the genus Carpophilus are significant pests of a wide variety of fruits and grains and are also vectors of harmful microorganisms. The beetles are difficult to control with conventional insecticides because the beetle damage typically occurs just before harvest, when toxic residues must be avoided. These insects are generally attracted to scents such as from overripe or decomposing fruit. Starting in the 1960's, research was done to develop fermenting fruit and similar materials as trap baits, initially with the intent of achieving beetle control. These studies pro

In temperate climates, there has been an increasing interest by fruit growers to implement the use of high tunnels, using a variety of coverings, to extend the season for fruit production. High tunnels also provide an opportunity to enhance insect pest management, via physical exclusion, and thus support reductions in insecticide use. Due to increasing pest pressure by the Japanese beetle, Popillia japonica Newman, in Midwest U.S. raspberry, a 3-year study (2017–2019) was conducted to evaluate the efficacy of selected high tunnel coverings to suppress adult beetle populations and minimize adul

Usually June/July adult beetle emerge and feed on hosts like neem and Melia rubra which the farmers plant them as wind breaks along the
