News Update on Pest Control Research: Aug – 2019

Sustainable pest regulation in agricultural landscapes: a review on landscape composition, biodiversity and natural pest control

Agricultural intensification has resulted in a very simplification of agricultural landscapes by the enlargement of agricultural land, enlargement of field size and removal of non-crop surroundings. These changes ar thought of to be a crucial reason for the fast decline in farmland multifariousness, with the remaining multifariousness targeted in field edges and non-crop habitats. The simplification of landscape composition and also the decline of multifariousness could have an effect on the functioning of natural cuss management as a result of non-crop habitats give requisites for a broad spectrum of natural enemies, and also the exchange of natural enemies between crop and non-crop habitats is probably going to be diminished in landscapes dominated by productive cropland.

Agroecosystem Diversity and Pest Control: Data, Tentative Conclusions, and New Research Directions

Recent criticism of the idea that augmented diversity ends up in increased stability has led to widespread skepticism concerning the worth of victimization ecological theory to recommend ways of agricultural diversification to higher management insect pests. a complete of associate degreed fifty} printed studies that examine the result of diversifying an agroecosystem on insect pesterer abundance are summarized; 198 total animal species were examined within these studies: fifty three of those species were found to be less superabundant in the additional wide-ranging system, eighteen were additional superabundant within the wide-ranging system, Sept. 11 showed no distinction, and 2 hundredth showed a variable response.

Plant strategies of manipulating predatorprey interactions through allelochemicals: Prospects for application in pest control

To understand the role of allelochemicals in predator-prey interactions it’s not spare to check the activity responses of predator and prey. One ought to elucidate the origin of the allelochemicals and bear in mind that it should be settled at another organic process level. These aspects area unit reviewed for predator-prey interactions generally and illustrated well for interactions between predatory mites and phytophagic mites. within the latter system there’s activity and chemical proof for the involvement of the host plant in production of volatile allelochemicals upon injury by the herbivores with the consequence of attracting predators. These volatiles not solely influence predator behavior, however additionally prey behavior and even the attractiveness of near  plants to predators. [3]

Establishing next-generation pest control services in rice fields: eco-agriculture

Pesticides are normally utilized in food crop production systems to regulate crop pests and diseases and guarantee most yield with high market price. However, the buildup of those chemical inputs in crop fields will increase risks to diverseness and human health. additionally, individuals are progressively seeking foods during which chemical residues are low or absent which are made in an exceedingly property fashion. quite 1/2 the world’s human population depends on rice as a staple food and chemical pesticides to regulate pests is that the dominant paradigm in rice production.

Abundance and Incidence of Zucchini (Cucurbita pepo L) Flies in the Korhogo Department of Northern Côte d’Ivoire and Pest Control Methods Used by Farmers

To improve the assembly of zucchini in Ivory Coast and notably in to Korhogo Department, a study was applied at the Peleforo Gon Coulibaly University analysis web site and at four farmers’ sites throughout dry and rainy seasons. On every plot, the quantity of healthy and attacked fruits was evaluated, supported a random sample of one hundred fruits. The attacked fruits were transported to the laboratory and incubated to work out the motivating agents. The strategies and pesticides wont to management insect pests by farmers were listed. throughout the season, 86.06% of the fruit was attacked by flies whereas thirteen.94% remained healthy. within the season, for a complete of nine,617 controlled fruits, 7,439 (77.35%) were healthy and twenty two.65% were attacked. Four insects species emerged from troubled fruit. They were Bactrocera cucurbitae, Dacus ciliatus, Dacus bivittatus, happiness to the family of Tephritidae, and Scaeva pyrastri happiness to Syrphidae. the tactic employed by farmers to manage pests wasn’t effective. finally, flies represent the limiting issue of zucchini production throughout the season in to Korhogo Department.
