Age-specific life tables of Aonidiellaaurantii (Maskell) (Hemiptera: Diaspididae) and its parasitoid Aphytismelinus DeBach (Hymenoptera: Aphelinidae)

Abstract

Introduction Australia has an important role in citrus (Citrus spp., Rutaceae) production in the world, and this production has increased (FAO, 2017). Many pest species such as Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), Aonidiella aurantii, Sasseita oleae (Gomez-Menor Ortega) (Hemiptera: Coccidae), Toxoptera citricada (Kirkaldy) (Hemiptera: Aphididae), Phyllocnistis citrella Stainton (Lepidoptera: Gracillaridae), et al. were observed in WA (Western Australia) citrus orchards (Sonia, 2006). Growers have followed various methods to avoid damage caused by these pests. Biological control is one of these methods (FAO, 2017; Pekas, 2011a; Uygun and Satar, 2008). There are 32 species in the genus Aonidiella Berlese & Leonardi, which is a genus of scale insects in the family of Diaspididae (Hemiptera), the armoured scale insects (Ben-Dov, 2006). California red scale Aonidiella aurantii (Maskell) occurs on numerous host plants throughout the world. They attack different crops such as fruit trees and ornamental plants all over the world, and cause heavy damage to the plants. Individual species infest leaves, fruits, branches, main stems, trunks, and roots. They are distributed throughout the world except in the cold extremes of the Arctic and Antarctic regions (Miller, 2005). California red scale Aonidiella aurantii is one of the most important pests infesting citrus trees in different parts of the world (

Diaspis echinocacti (Hemiptera: Diaspididae) on cactus pear cladodes: biological aspects at different temperatures

“…The greater survival of D. echinocacti females at 28º C and of males at 25 ºC and 30 ºC indicates that these temperatures are ideal for this insect, as reported for Aonidiella aurantii (Maskell, 1879) (Hemiptera: Diaspididae) between 23 ºC and 27 ºC on butternut squash (Mohammed et al, 2020).…”

“…The highest and lowest total numbers of eggs and eggs/female/day of D. echinocacti at 25 ºC and 33 ºC, respectively, indicate that the latter temperature is inadequate for oviposition of this scale mealybug as reported for Aspidiotus nerii Bouché (Homoptera: Diaspididae) females fed potato with 99.7 and 55.1 eggs per female at 24 ºC and 28 ºC (Gerson and Hazan, 1979) and A. aurantii on butternut squash with 109.7 and 129.4 eggs per female at 23°C and 27°C, respectively (Mohammed et al, 2020). The inverse correlation between the development periods of D. echinocacti females and males with temperature confirms impact of this parameter on males and females of this insect (Li et al, 2017).…”

Current Situation of Tetranychus urticae (Acari: Tetranychidae) in Northern Africa: The Sustainable Control Methods and Priorities for Future Research

“…Similar results were cited in Algeria and Tunisia, which are under the same climatic conditions as Morocco [39]. In Egypt, spider mite was found in fruit trees and ornamental vegetation, causing serious damage, according to the infestation rates on these plants [40,41]. The differences in infestation rates can be attributed to the variation of environmental conditions, planting dates, and age of plantation [42].…”

A Comparative Analysis of Adult Hydronephrosis at a Tertiary Care Hospital: Uncovering Uncommon Etiologies

“…Similarly, the value of retrospective analyses in such settings is exemplified by (5), who investigated stroke admissions in northern Tanzania, providing insights into disease patterns and outcomes. In the realm of hematological disorders, (6)emphasized the importance of age-specific analyses through their evaluation of pancytopenia/bicytopenia in both adult and pediatric patients, using parameters such as hematological markers and bone marrow studies (6). This approach is echoed in the work of Haghpanah et al (2020), who investigated the cost-effectiveness of blood transfusion practices in neonates, a study pivotal for resource optimization in developing countries (7).…”
