“…The pink hibiscus mealybug, Maconellicoccus hirsutus (Green) (Hemiptera: Pseudococcidae), is a species originally from South Asia that quickly spread throughout the world [1,2] . Worldwide, M. hirsutus has been found attacking more than 350 species, including fruit, vegetables, ornamentals, coffee, and cotton [3,4,5] . The species was first reported in Brazil in 2010 in the State of Roraima, and since then it has spread to other Brazilian states bringing economic losses to the affected regions.…”

“…The species was first reported in Brazil in 2010 in the State of Roraima, and since then it has spread to other Brazilian states bringing economic losses to the affected regions. In 2013, the pest was detected in the cocoa crop in the regions of Bahia and Espírito Santo in the municipality of Linhares -ES [5] . The pink hibiscus mealybug is a polyphagous pest, it can cause severe damage and in high populations, it can lead the plant to death.…”

Maconellicoccus hirsutus (Hemiptera: Pseudococcidae) is a polyphagous pest, attacks several crops of economic importance, including cocoa and coffee. Due to its rapid dissemination, studies are needed to develop management programs to combat this pest, as few studies seek the effectiveness of alternative products such as plant extracts, which can be promising in its control. Therefore, this work aimed to evaluate the efficiency of the aqueous extract of the fruits of chili pepper Capsicum frutescens (Solanaceae) in the management of the pink hibiscus mealybug. The tests were carried out in acclimatized chambers regulated at a temperature of 25 ± 1 ºC, relative humidity of 70 ± 10%, and a 12hour photophase. The treatments consisted of five extract concentrations: 0.0, 2.5, 5.0, 7.5, and 10% (weight/volume). Coffee leaves were submerged in the aqueous solution of pepper extract and mounted in Petri dishes with agar solution to transfer the mealybugs. Each treatment consisted of 10 repetitions with 10 young mealybugs each. The experiment was evaluated 24, 48, and 72 h after the procedure. Data were submitted for analysis of variance and regression test (p≤0.05). Lethal concentration (LC50) was estimated using Probit analysis. The mortality of mealybugs increased with the increase in extract concentrations, with mortalities greater than 70% from the lowest concentration. The data fit the Probit model, with χ² of 1.0478 (p > 0.05) and a curve slope of 1.7799. The LC50 was estimated at 0.96%. Thus, the aqueous extract of Capsicum frutescens fruits is promising for the management of M. hirsutus.

“…In Espírito Santo, its first report occurred in 2012, in the southern region of the state (CULIK et al, 2013). This species is registered as a potential pest for several host plants from 78 botanical families (GARCÍA MORALES et al, 2016;MARTINS et al, 2019), and its feeding habit, which consists of sucking the sap of the plant and injecting a toxic substance, can cause the malformation of the leaves and fruits, as well as withered apical growth, which may directly inhibit the development of some plant species (FORNAZIER et al, 2017;HOLTZ et al, 2019). Considering the damage caused by pest species in crops of economic interest, synthetic chemicals are still the most used control method to combat the main agricultural pests.…”

The pink mealybug, Maconellicoccus hirsutus (Green) (Hemiptera: Pseudococcidae) is a polyphagous pest species that has been reported in about 350 species of host plants worldwide. Usually, the use of synthetic chemicals is still the most used control method for the control of agricultural pests. The objective of this present work was to evaluate the potential of the interaction of oils extracted from the species Ricinus communis L. (castor) and Jatropha curcas L. (jatropha) (Euphorbiaceae) in the form of direct and indirect application on M. hirsutus. The experiments were conducted in air-conditioned chambers at a temperature of 25 ± 1ºC, relative humidity 70% ± 10 and a photophase of 12h. The 3% concentration was used in the tests, with 11 interaction ratios between the oils. Individuals' mortality was assessed at 24, 48 and 72 hours after spraying. The results of the interactions indicated up to 78% mortality of individuals in the ratio 90% castor + 10% jatropha via indirect application, while in the direct application on individuals they presented 53% mortality in the ratio 40% castor + 60% jatropha. The interactions between castor and jatropha oils have demonstrated potential in the management of pink mealybug by direct or indirect application.

“…it is not distributed throughout the national territory and can cause damages in more than 200 species of plants, as registered in other countries. Brazil offers ideal climatic conditions for its development, being its greatest economic impact on fruit growing, mainly in fields of cacao (Theobroma cacao) [1]. While feeding, the mealybugs introduce toxic substances in the plants, causing poor formation of leaves and fruits, apical growth, and may lead to premature senescence of flowers [2].…”

The objective of this study was to evaluate the insecticidal effect of aqueous extract of castor bean (Ricinus communis) cake for the control of Maconellicoccus hirsutus. The toxicity tests were performed in the laboratory. Subsequently lethal concentrations 50 and 90% (LC50and LC90, respectively) were estimated. Tween80® + distilled water was used as surfactants and solvent respectively. The assay was performed in petri dishes containing a Coffea canephora leaf disc. The spraying was carried out in Torre de Potter spray tower. The extract was toxic to mealybug and the mortality data was adapted to the probit model. Estimates of LC50 and LC90 were 5.32% and 29.30%, respectively. It was concluded that the aqueous extract of R. communis cake is promising for the management of M. hirsutus.
