Phyllocnistis citrella Stainton, commonly known as the citrus leafminer, threatens global citrus production. This study focuses on elucidating the population dynamics and spatial distribution of P. citrella in lemon orchards located in Northern Portugal. From May to December, using delta traps with sexual pheromones, the levels of the adult population were monitored, and aggregation indices were calculated. Five distinct density peaks are observed, with the highest recorded in late July to early August. Spatial distribution consistently indicated an aggregated pattern. However, temporal variation in distribution was observed on specific dates. According to our results, it is suggested deploying two or three traps per hectare during peak density periods. This study significantly advances our understanding of P. citrella dynamics, emphasizing the need to consider spatial and temporal patterns for effective pest management. The outcomes underscore the importance of further exploration into factors influencing distribution patterns to refine control strategies. These insights are crucial for devising targeted and efficient measures to mitigate the impact of P. citrella on citrus orchards globally.

“…Half-monthly data on acalypha shrubs were utilized for discussing the population abundance of F. virgata by calculating the average total population per branch, either increasing or decreasing (±) the standard error, which was applied to evaluate the population estimations. A direct inspection for mealybugs was performed at the same time as the aforementioned inspections (Bakry and Arbab, 2020;.…”

“…Many researchers have concluded that hemipteran pests have a high aggregated distribution behavior. Example: Chauliops fallax (Hemiptera: Malcidae) on soybean (Bala and Kumar, 2018), Waxiella mimosae on sunt trees (Bakry, 2018), Parlatoria oleae on mango trees (Bakry, 2020), Aulacaspis tubercularis (Hemiptera: Diaspididae) on mango trees (Bakry and Abdel-Baky, 2020), Icerya seychellarum on guava trees (Bakry and Arbab, 2020), Schizaphis graminum (Hemiptera: Aphididae) (Bakry and Shakal, 2020), and Phenacoccus solenopsis on okra plants . The data presented in Table (4) and Figure (5) showed the toxicity activity of some insecticides against F. virgate after 72 hrs of treatment.…”

“…Even though ensuring accuracy and precision in sampling is crucial for effective mealybugs research and decision-making in management. Bakry, and Arbab (2020) conducted a review on the fundamental models that establish the relationship between the variance (Ơ2) and the arithmetic mean (µ) of mealybug counts in a population. These models are as follows: (a) the positive binomial model, which is applicable when the variance is significantly lower than the mean (Ơ2 < µ), (b) the Poisson series, which serves as the basic framework when the variance is almost equal to the mean (Ơ2 = µ), and (b) the negative binomial, which is the most flexible equation among various possibilities and is applicable when the variance is significantly larger than the mean (Ơ2 > µ) (He et al 2022).…”

The present experiment was implemented in the garden of the El-Mattana Agricultural Research Station, Luxor area, Egypt (2021/2022 and 2022/2023) to study the population seasonal and spatial distribution of the mealybug, F. virgata concerning some weather parameters and its control. During each year of the study, F. virgata was discovered on acalypha shrubs from the period on October 1 st to January 15 th , after which the insect infestation disappeared until July 15, and then the insect began to appear again from August 1 st to September 15 th (the end of taking readings for each year). It had two peaks of activity annually, which were observed on November 1 st and September 15 th . Multiple linear regression mathematical model mentioned that the combined effect of all weather parameters, namely maximum and minimum temperature, relative humidity, sunny shine, and solar radiation, reached 84.21% in 2021/2022 and 83.99% in 2022/2023 on the variation in mealybug numbers. The gathered data were examined by analyzing patterns of distribution, revealing that all dispersal metrics for the different stages of F. virgata displayed a significant tendency towards clustering throughout the two years. After 72 hours of testing the effectiveness of the insecticides, the activities of the studied pesticides varied, as it was found that Imidacloprid was found to be the most effective insecticide than the other tested pesticides for both F. virgata third instar nymphs and adult females. However, the Bioranza pesticide was less effective.
