First record of the mealybug Phenacoccus madeirensis Green, 1923 (Hemiptera: Coccomorpha: Pseudococcidae) in Algeria

The mealybug Phenacoccus madeirensis Green (Hemiptera: Coccomorpha: Pseudococcidae) is recorded from Algeria for the first time. This pest was first detected in the summer of 2018 in private gardens in Salamandre, on the coastal side of Mostaganem City in north‐western Algeria, feeding on three ornamental plants: Hibiscus rosa‐sinensis L., Hibiscus syriacus L. (Malvaceae) and Cestrum nocturnum L. (Solanaceae). In October 2018, it was also found on Aloysia citriodora Palàu (Verbenaceae) growing near Hibiscus. The first samples collected had been attacked by hymenopteran parasitoids. Surveys of ornamental nurseries and greenhouses growing vegetables in the area indicate that, at present, P. madeirensis seems to be restricted to ornamental plants. More surveys over larger areas are needed to determine its distribution and the likely origin of its introduction to Algeria.     

First record of the Madeira mealybug,Phenacoccus madeirensis Green (Hemiptera: Pseudococcidae), in Jordan

The Madeira mealybug, Phenacoccus madeirensis (Hemiptera: Pseudococcidae), is recorded from Jordan for the first time. Specimens were collected from heavily infested ornamental geranium plants, Pelargonium sp. (Geraniaceae), Chrysanthemum sp. (Asteroideae), Hibiscus rosa‐sinensis L. (Malvaceae), Kalanchoe blossfeldiana Poellnitz (Crassulaceae) and basil, Ocimum basilicum L. (Lamiaceae). In addition, this mealybug was taken from infested leaves of cherry tomato, Solanum lycopersicum L., and sweet pepper, Capsicum annuum L. (Solanaceae). Kalanchoe blossfeldiana is recorded as a new host for P. madeirensis. Slide mounts were prepared, and voucher specimens were preserved at the University of Jordan Insect Museum. An urgent survey should be initiated to determine the current distribution of the pest in Jordan. Inspection of ornamental nurseries should be given priority and plant protection officials should pay particular attention to this serious pest.     

Phenacoccus madeirensis (Hemiptera: Pseudococcidae): a new species of mealybug in Tunisia

In August 2013, Phenacoccus madeirensis Green, 1923 (Hemiptera: Pseudococcidae) was identified for the first time in Tunisia, in the region of Akouda (Sousse, coastal area of Tunisia) on Cestrum nocturnum (Solanaceae) during a survey. The infestation was observed on leaves, shoots and also on the collar. This is the first record of P. madeirensis in Tunisia and the first record of this pest in North Africa. Two other mealybugs Peliococcus cycliger and Planococcus citri were also recorded during this survey. They have previously been reported in Tunisia.     

Icerya purchasi (Homoptera: Margarodidae) on Rosmarinus officinalis (Lamiaceae), a new host plant record for Greece

Since July 2008, Rosmarinus officinalis plants in Greece have been observed to be infested by the cottony cushion scale, Icerya purchasi Maskell. This is the first time that I. purchasi has been found on R. officinalis in Greece. Observations made have shown that this scale insect prefers to initially attack the stems of R. officinalis plants.

Molecular and morphological identification of the mealybug,Phenacoccus solani Ferris (Hemiptera: Pseudococcidae): first report in Egypt

During the summer and autumn of 2016, pumpkins, Cucurbita spp. (Cucurbitaceae), were observed to be infested by mealybug species. Populations were collected on various pumpkin fruits from Rosetta, a port city at the North‐Western Nile River delta, Lower Egypt. This study aimed to identify the principle mealybug species infesting the major pumpkin‐producing regions in Egypt, by molecular and morphological characterization. DNA from 15 specimens and morphological data from 22 specimens were used to confirm the identity of the mealybug species. The species present were identified as Phenacoccus solani Ferris, Phenacoccus solenopsis Tinsley, and Planococcus citri (Risso). This is the first record of Phenacoccus solani Ferris (Hemiptera: Pseudococcidae) in Egypt.     

The pink hibiscus mealybug,Maconellicoccus hirsutus (Green) (Hemiptera: Coccomorpha: Pseudococcidae), a new threat to Israel's agriculture and horticulture

The invasive mealybug Maconellicoccus hirsutus (Green) (Hemiptera: Coccomorpha: Pseudococcidae) is reported in Israel for the first time. This damaging mealybug was detected in two locations in Northern Israel on various ornamental plants. Its principal parasitoids, Anagyrus kamali Moursi and Gyranusoidea indica Shafee (Hymenoptera: Encyrtidae), were both recovered from the collected samples. Maconellicoccus hirsutus is highly polyphagous but particularly thrives on members of the plant families Fabaceae, Malvaceae and Moraceae.     

First record of Aleurocanthus spiniferus (Homoptera: Aleyrodidae) in Apulia,Southern Italy

Temperature-dependent parasitism and development in Aenasius arizonensis Girault (Hymenoptera: Encyrtidae), a solitary endoparasitoid of Phenacoccus solenopsis (Hemiptera: Pseudococcidae)

Ophmella communa (Coleoptera: Chrysomelidae) is a biological control agent of Ambrosia artemisiifolia (Asterales: Asteraceae). To reveal its climate adaptation, the effect of temperature on life traits of Aenasius arizonensis, a parasitoid of Phenacoccus solenopsis was studied. The results showed that both the highest parasitism and emergence rates of A. arizonensis were observed at 31 °C. The parasitism and emergence rates of the parasitoid significantly increased with the increasing temperature from 19 °C to 31 °C, but dropped when the temperature exceeded 31 °C. Female ratio reached a higher value at 19, 22, 31, 34 or 37 °C. The minimum threshold temperatures for female and male parasitoids were 11.5 and 11.2 °C, respectively. The effective accumulative temperatures for the parasitoid to develop from eggs to both female and male adults were 222.2 day-degrees. Since the highest parasitism rate, the highest emergence rate and a higher female ratio were observed at 31 °C, we conclude that the optimum temperature for mass rearing of A. arizonensis is 31 °C in the insectary based on the results of our study.

The cotton mealybug, <Emphasis Type="Italic">Phenacoccus solenopsis</Emphasis> Tinsley (Hemiptera: Pseudococcidae) in Israel: pest status,host plants and natural enemies

In Israel, the cotton mealybug Phenacoccus solenopsis Tinsley, an invasive scale insect, was reported for the first time in the Jordan Valley in 2008 on basil (Ocimum basilicum) and bell pepper (Capsicum annuum). This mealybug is highly polyphagous with economic and environmental impacts. Since then, Ph. solenopsis has spread to almost every region of Israel and developed high populations on several ornamental plants, mainly Hibiscus sp. (Malvaceae) and Lantana sp. (Verbenaceae). It has become a pest in greenhouses, mainly on bell pepper, tomato, and eggplant (Solanaceae) and a serious threat in cotton fields. Fourteen species of insect natural enemies have been found in association with Ph. solenopsis in Israel the common ones were: Aenasius arizonensis (Girault) (Hym. Encyrtidae), Cheilomenes propinqua (Mulsant), Hyperaspis vinciguerrae (Capra); H. polita Weise, Exochomus nigripennis (Erichson), Parascymnus varius Kirsch and Scymnus flagellisiphonatus (Fursch) (Col., Coccinellidae). To date, the population density of Ph. solenopsis in Israel is steeply decreasing in most regions of Israel due to the activity of A. arizonensis. An identification key to distinguish between adult females of the eight species belonging to the genus Phenacoccus in Israel is also provided.     

Demographic parameters and biological features of <Emphasis Type="Italic">Phenacoccus solenopsis</Emphasis> Tinsley (Hemiptera: Pseudococcidae) on four ornamental plants

The development, reproduction and life table parameters of the cotton mealybug, Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) on four ornamental plants (Hibiscus rosa-sinensis L., H. syriacus L. (Malvaceae), Brugmansia aurea Lagerh., Cestrum nocturnum L. (Solanaceae)) were studied at 25 ± 2 °C, 60% ± 10% r.h., and 16 hours daily artificial light. Life table data were analyzed by using an age-stage, two-sex life table. The highest intrinsic rate of increase (0.2911 d^-1), finite rate of increase (1.3380 d^-1), net reproductive rate (258.0 nymphs/female) and gross reproduction rate (342.6 nymphs/female), as well as the shortest mean generation times (19.1 days) were obtained when the mealybug was reared on H. syriacus.

Biological Control of the Hibiscus Mealybug, Maconellicoccus Hirsutus Green (Hemiptera: Pseudococcidae) in the Caribbean

The hibiscus mealybug, Maconellicoccus hirsutus Green, was first reported in the Caribbean in 1994 in Grenada. This was the first record of the insect as a major pest in the New World. By the beginning of 2001, the pest had spread to over 25 territories from Guyana and Venezuela in the South to Bahamas in the North. The pest has also extended its distribution to Central America (Belize) and North America (California, USA). Early attempts to control the pest using pesticides resulted in failure and a classical biological control approach was adopted. Several exotic natural enemies were introduced but control was attributed to Anagyrus kamali Moursi and Cryptolaemus montrouzieri Mulsant. In all countries where biological control was implemented, this resulted in success. This paper reviews the remarkable success story. Information is provided on the distribution and factors leading to rapid spread of the pest, its pest status and resultant economic losses, and implementation of the biological control effort.
