“…The consumption of P. citri nymphs by third-instar larvae represented 81% of the total observed for the entire larval phase of the predator. These results reiterate the greater voracity of this instar about the others, as usually reported in the scientific literature for larvae of this chrysopid (Fonseca et al, 2015;Cuello et al, 2019) or other species of Chrysopidae (Elango and Sridharan, 2017;Rahman et al, 2017;Farhan et al, 2019;Moreira et al, 2019).…”

“…Recently, C. externa was registered in Brazil for commercialization and control of different pest species (Agrofit, 2022). This predator is known for its voracity against aphids, whiteflies, thrips, psyllids, mites, and mealybugs (Pedro-Neto et al, 2008;Morando et al, 2014;Castro et al, 2016;Gamboa et al, 2016;Cuello et al, 2019;Luna-Espino et al, 2020). The larvae also feed on P. citri (e.g., Carvalho et al, 2008), but in some cases, the prey has negative effects on the biological parameters of the predator (Pedro Neto et al, 2008).…”

This study aimed to determine the consumption of Planococcus citri (Risso, 1813) (Hemiptera: Pseudococcidae) nymphs and the predator:prey ratio required for high predatory efficacy and survival of Chrysoperla externa (Hagen, 1861) (Neuroptera: Chrysopidae) larvae under different densities of prey, reared in rose bushes. Consumption by first-, second-, and third-instar larvae of C. externa was assessed. The predatory efficiency and survival of the predator were calculated for larvae in the second instar under densities of 20, 40, 80, 120, and 160 nymphs of P. citri and predator:prey ratios of 1:5, 1:10, and 1:20. The assessments were performed after 24 and 48 hours of exposure between species. There was increasing consumption throughout the larval development of C. externa. The predator:prey ratios 1:5 and 1:10 were the most efficient for P. citri population reduction, but the 1:5 ratio led to lower survival of larvae than the 1:10 and 1:20 ratios. There was a positive correlation between C. externa larval density and cannibalism (ρ = 0.45) and a negative correlation between predator density and P. citri population density (ρ = -0.81). Third-instar larvae consume more P. citri nymphs than second-instar larvae. Second-instar larvae of this lacewing released at a 1:20 ratio caused total mortality of mealybug nymphs within 48 hours, regardless the density of P. citri, with high larvae survival of C. externa.

“…The quality of the prey species has a direct impact on the growth, development, and reproduction of predatory insects. Preys with high nutritional quality promote a fast development and allow green lacewings to reach their maximum reproductive potential (CUELLO et al, 2019). Regarding the parameters of the adult stage, the results showed that oviposition and post-oviposition periods, longevity, and fecundity of C. everes insects were higher when they were fed on E. kuehniella eggs, when compared to those fed on M. hirsutus.…”

BIOLOGICAL ASPECTS OF Ceraeochrysa everes (NEUROPTERA: CHRYSOPIDAE) FED ON PINK HIBISCUS MEALYBUG

The invasive pink hibiscus mealybug, Maconellicoccus hirsutus (Green) (Hemiptera: Pseudococcidae), is a pest that threatens the production of fruits, vegetable, and ornamental plants in Brazil. It is a phytophagous insect with a wide range of hosts; thus, there is an increasing demand for sustainable environmental-friendly control methods, such as biological control. This study aimed to investigate biological parameters of Ceraeochrysa everes (Neuroptera: Chrysopidae) fed on 2nd instar nymphs of M. hirsutus and eggs of Ephestia (Anagasta) kuehniella (Zeller) (Lepidoptera: Pyralidae). The duration of the immature stages of C. everes was longer when the predator was fed on 2nd instar nymphs of M. hirsutus, compared to the control (E. kuehniella). The survival rate of immature C. everes was 82.5% and 100% when fed on 2nd instar nymphs of M. hirsutus and eggs of E. kuehniella, respectively. The type of food resource offered at the larval stage affected the pre-oviposition, oviposition, and post-oviposition periods and the longevity of C. everes females. Adult females C. everes from immature individuals fed an exclusive diet of E. kuehniella eggs had longer oviposition, fecundity (daily and total), fertility, and post-oviposition periods and longevity. Ceraeochrysa everes has the capacity for predation, development, and reproduction while having 2nd instar nymphs of M. hirsutus as food resource. Therefore, C. everes has a promising potential for controlling M. hirsutus.

“…Despite some inconsistent laboratory vs. field data for SWD predation [ 13 , 14 , 16 , 23 ], other studies have shown that Chrysopids are promising predators to be used in the control of other insect pests: Chrysoperla spp. larvae might be used to control Tuta absoluta (Meyrick) (tomato pinworm) [ 39 ], Frankliniella occidentalis Pergande (western flower thrips) [ 40 ], Melanaphis sacchari (Zehntner) (sugarcane aphid) [ 41 ] or Glycaspis brimblecombei Moore (eucalyptus aphid) [ 42 ]. However, the role of chrysopids remains unclear, as the collected individuals were adults, and not all adults of the family Chrysopidae are predators.…”

DNA screening of Drosophila suzukii predators in berry field orchards shows new predatory taxonomical groups

et al. 2021

View full text Add to dashboard Cite

Drosophila suzukii (spotted wing drosophila, SWD) is a pandemic quarantine pest that attacks mostly red fruits. The high number of life cycles per year, its ability to rapidly invade and spread across new habitats, and highly polyphagous nature, makes this a particularly aggressive invasive species, for which efficient control methods are currently lacking. The use of native natural predators is particularly promising to anchor sustainable and efficient measures to control SWD. While several field studies have suggested the presence of potential predatory species in infested orchards, only a few confirmed the presence of SWD DNA in predators’ gut content. Here, we use a DNA-based approach to identify SWD predators among the arthropod diversity in South Europe, by examining the gut content of potential predator specimens collected in SWD-infested berry fields in North Portugal. These specimens were morphologically identified to the family/order, and their gut content was screened for the presence of SWD DNA using PCR. New SWD predatory taxonomical groups were identified, as Opiliones and Hemerobiidae, in addition to known SWD predators, such as Hemerobiidae, Chrysopidae, Miridae, Carabidae, Formicidae and Araneae. Additionally, the presence of a spider family, Uloboridae, in the orchards was recorded for the first time, posing this family as another SWD-candidate predator. This study sets important bases to further investigate the potential large-scale use of some of these confirmed predator taxa for SWD control in South Europe.
