Pterochloroides persicae population on peach showing symptoms of infection with entomopathogenic fungi.
Source publication
Symptoms of mycosis of Pterochloroides persicae (Cholodkovsky 1899) (Hemiptera, Aphididae) in a peach and almond orchard were recorded in April 2011. The causal agent was morphologically identified. Polymerase chain reaction (PCR) of the internal transcribed spacer region (ITS1 and ITS4) was used for molecular identification and verification of the...

... Holocyclic life cycle of M. persicae was demonstrated in several others studies [4,5,31]. In contrast, on herbaceous plants, only viviparous parthenogenetic females of M. percicae are present throughout the year (anholocyclic life cycle) [33,34]. It is also an heteroecious holocyclic specie [35]. ...
Aphids are among the most obnoxious pests of almond and peach in Tunisia. Accurate control of these insect pests requires the determination of their major species as well as the thorough understanding of the biology and identification of their major natural enemies. The scope of this chapter is to identify the main aphid species infesting almond and peach in Tunisia, to describe their biology, to determine their natural enemies and to study their efficiency as biological agents. A field survey was carried out during 2007–2016 period at Almond and Peach orchards in Tunisia. Results demonstrated the presence of Hyalopterus pruni Geoffroy, Hyalopterus amygdali Blanchard, Brachycaudus amygdalinus Schouteden, Myzus persicae Sulzer, Brachycaudus schzartwi Borner and Pterochloroides persicae Cholodkovsky. Biological study of recorded species demonstrated the presence of holocyclic and anholocyclic life cycle depending on host trees and aphid species. For predators, four families (Coccinellidae, Syrphidae, Chrysopidae, Cecidomyiidae) and one parasitoid and two entomopathogenic fungi species were identified. For control of Pterochloroides persicae, results showed that Pauesia antennata Mukergi was more efficacy than Coccinella algerica Kovar. This parasitoid should be reared and used in future integrated pest management program in almond and peach orchard in Tunisia.

Aphids are among the most obnoxious pests of almond and peach in Tunisia.
Accurate control of these insect pests requires the determination of their major
species as well as the thorough understanding of the biology and identification of
their major natural enemies. The scope of this chapter is to identify the main
aphid species infesting almond and peach in Tunisia, to describe their biology, to
determine their natural enemies and to study their efficiency as biological agents.
For this reason, a field survey was carried out between 2007 – 2016 at Almond
and Peach orchards in the north, middle and south of Tunisia. Our results
demonstrated the presence of Hyalopterus pruni Geoffroy, Hyalopterus
amygdali Blanchard, Brachycaudus amygdalinus Schouteden, Myzus persicae
Sulzer, Brachycaudus schzartwi Borner and Pterochloroides persicae
Cholodkovsky infesting those orchards. Study of biology of recorded aphid
species (reproduction type) demonstrated the presence of two types of cycle life
(holocyclic, anholocyclic) depending of host trees and aphid species. Our
population studies showed the presence of predators belonging to four insect
families of Coccinellidae, Syrphidae, Chrysopidae, Cecidomyiidae and one
parasitoid (Hymenoptera; Braconidae) and two entomopathogenic fungi species.
In order to establish a biological control strategy against Pterochloroides
persicae (Hemiptera; Lachninae), we experimented with the predator Coccinella
algerica Kovar (Coleoptera; Coccinellidae) and the parasitoid (Pauesia
antennata Mukerji (Hymenoptera; Braconidae)). Our results showed that P.
antennata was more efficacy in controlling P. persicae than C. algerica. This
parasitoid should be reared and used in future integrated pest management
program in almond and peach orchard in Tunisia.
