“…This suggests the need for adjustments (e.g., a cumulative level between evaluations as advocated by the IAP). This may explain why the initial focus of this pest within the orchard area is the edge; after that, it subsequently expands to the center (RAMOS et al, 2019), in small areas, where a proportion of the edge is much higher, small increases in the population, concentrated at the edges, compromise expressive volumes of fruits. Anther fact is that the first impulse of mated female fruit flies is to search for oviposition places after they have reached the orchards (KOVALESKI et al, 2000).…”

“…The primary hosts of A. fraterculus belong to the Myrtaceae family (SANTOS et al, 2018;BOLDO et al, 2019) and often grow on the borders of apple or pear orchards, providing an easy route for the pest to infest the crop field. Female flies move into the crop while looking for food and oviposition sites NORA, 2007;RAMOS et al, 2019), and they begin to attack apples soon after thinning (usually performed in November). These attacks continue until harvest (TEIXEIRA et al, 2011).…”

Anastrepha fraterculus the South American fruit fly, is an important insect pest in apple orchards of southern Brazil, especially in small farms, where it often causes total crop loss. Experiments were conducted to evaluate, during four crop seasons (2009/2010, 2010/2011, 2012/2013, and 2013/2014) in organic and conventional apple orchards in southern Brazil, the toxic bait formulation ANAMED™ (oils and waxes 49.0% + M7 attractant 24.2% + spinosad insecticide 0.1%) for its capacity to reduce the South American fruit fly population. ANAMED applications started after apples with an average diameter of 20 mm had been thinned, and they were made every 14 days until harvest. ANAMED was sprayed on non-crop vegetation growing on the edges of the orchards at a rate of 1.0 kg.ha-1. Adult fruit flies were monitored weekly using McPhail traps baited with Torula™ yeast. Injured fruits were evaluated seven days before harvest. ANAMED reduced the adult population of trapped fruit flies captured in all crop seasons and the injured fruit, except for the first year of evaluation (2009/2010). In conclusion, the sequential use of ANAMED toxic bait over time significantly reduced adult populations of A. fraterculus and the percentage of fruits injured by this pest.

“…На відміну від пестицидів, біологічні препарати характеризуються більш уповільненою дією, але й мають метатоксичний ефект і за певних умов можуть спричинити епізоотії у комах. Недоліком є також те, що ефективність біопрепаратів може знижуватись внаслідок несприятливих погодних умов: дощів, які здатні змивати препарат, низької температури, що послаблює активність живлення шкідників, а також ультрафіолетового випромінювання, яке частково інактивує бактерії [2][3][4][5].…”

“…One fundamental component of D. maidis management is its spatial dynamics and investigating it will allow us to identify how infestations begin and to understand colonization patterns, dispersal, and the role of the landscape structure in insect dynamics. [14][15][16] The spatial dynamics of D. maidis can be studied using spatial distribution models and geostatistics. Through geostatistics, we can detect spatial variability and quantify correlations among sampled points based on semivariograms.…”

BACKGROUND Since the last decade, Dalbulus maidis has become the primary pest in cornfields, particularly due to its ability to transmit plant pathogens. Dalbulus maidis is the main vector of the corn stunt spiroplasma and maize bushy stunt phytoplasma. However, there is little information available on this pest. Understanding its spatial dynamics may allow us to determine how its infestations begin and to identify its colonization patterns, dispersal, and the role of landscape structure on D. maidis dynamics. Thus, this study aimed to investigate within‐field spatial distribution and the factors associated with D. maidis abundance in five commercial fields. RESULTS In all fields, higher infestations occurred at the boundaries of the central pivot, showing a clear edge‐biased distribution. Ranges varied from 100.4 to 611.8 m, and our models' overall fit indicated strong to moderate spatial dependency. Additionally, correlation analyses indicated a positive effect of air temperature on the population of D. maidis. Conversely, rainfall negatively affected D. maidis. CONCLUSION This study provides essential guidance for improving D. maidis integrated pest management at regional and local scales. Based on its high dispersal ability, our study suggests the need for a legislative or regulatory method of control for D. maidis, especially in regions where corn has more than one growing season. © 2022 Society of Chemical Industry.
