The EFSA Panel on Plant Health performed a pest categorisation of Pseudococcus cryptus Hempel (Hemiptera: Pseudococcidae), the citriculus mealybug, for the EU. P. cryptus originates from Southeast Asia but is now established in East Africa, the Middle East and South America. The pest is not currently known to occur in the EU (there was a record once, in 2006, in a zoo/botanical garden from southern Spain). P. cryptus is not listed in Commission Implementing Regulation (EU) 2019/2072. It is polyphagous, feeding on plants in more than 90 genera in 51 families, and exhibits a preference for citrus (Citrus spp.) and palms (especially Cocos nucifera, Elaeis guineensis and Areca catechu). It is an important pest of citrus in Japan and parts of the Middle East, although in Israel, it is controlled by natural enemies. It is sexually reproductive, has six overlapping generations each year in Israel, and each female lays up to approximately 150 eggs, depending on temperature and host species. The main natural dispersal stage is the first instar, which crawls over the host plant or may be dispersed further by wind and animals. Plants for planting, fruits, vegetables and cut flowers provide potential pathways for entry into the EU. Climatic conditions in EU member states around the Mediterranean Sea where there is host plant availability, especially citrus, are conducive for establishment. The introduction of P. cryptus is expected to have an economic impact in the EU through reduction in yield and quality of important crops (mainly citrus) and damage to various ornamental plants. Phytosanitary measures are available to reduce the likelihood of entry and further spread. P. cryptus meets the criteria that are within the remit of EFSA to assess for this species to be regarded as a potential Union quarantine pest.

Algunas especies de Pseudococcidae y Putoidae (Hemiptera: Coccomorpha), son plagas importantes de las raíces del café en varias partes del mundo, para su manejo el control biológico es una alternativa; por lo tanto, en ocho departamentos cafeteros de Colombia se realizó la búsqueda e identificación de enemigos naturales de cochinillas harinosas de las raíces del café. Se recolectaron y depositaron en alcohol muestras de pseudocóccidos y putoideos de 520 fincas, las cuales se limpiaron y se separaron por color y tamaño. Se encontraron 120 especímenes de enemigos naturales en 44 fincas parasitando cochinillas harinosas de las familias Putoidae y Pseudococcidae. Caldas presentó el mayor porcentaje de fincas con parasitoides con 15,3%, le sigue Antioquia con 14,1%, Cauca con 13,8%, Valle del Cauca con 10,4 %, Tolima con 4,2%, Risaralda con 3,8 % y por último Quindío con 1,2%. Posteriormente, se visitaron nuevamente 20 de los predios donde hubo parasitismo y se recolectaron individuos de cochinillas harinosas, las cuales se transportaron vivas al laboratorio. En las cámaras de cría de las cochinillas harinosas emergieron 28 avispas parasitoides adultas, i.e. Aenasius caeruleus Brues, 1910, Aenasius bolowi Mercet, 1947, Aenasius tachigaliae (Brues, 1922), Aenasius af. mitchellae Noyes and Ren, 1995, Zarhopalus putophilus Bennett, 1957, Hambletonia pseudococcina Compere, 1936, Hambletonia sp., Prochiloneurus af. dactylopii (Howard, 1885), Leptomastix sp., Cicoencyrtus sp. (Hymenoptera: Encyrtidae) y cinco adultos cecidómidos (Diptera: Cecidomyiidae). También se registraron dos especies de coccinélidos (Coleoptera: Coccinellidae) y un hongo antagonístico Trichoderma sp. De estos hallazgos puede concluirse que existen varias especies de enemigos naturales que están ejerciendo control natural en campo sobre las cochinillas harinosas que infestan las raíces del café. Se recomienda explorar una alternativa de control biológico por aumentación.

Mealybug predator, Cryptolaemus montrouzieri Mulsant (Coleoptera: Coccinellidae), is an effective biocontrol agent against various species of mealybugs. This study was aimed to develop a protocol for mass production of C. montrouzieri with the aid of two mealybug host species; Planococcus minor and Pseudococcus viburni, under laboratory conditions. The predator was reared on P. minor and P. viburni, using two substrates; local pumpkin (Cucurbita moschata) and Malaysian pumpkin (Cucurbita maxima). The incubation period of eggs, durations of first instar larvae and pupae of C. montrouzieri were significantly different with two host species (p<0.05). Production of C. montrouzieri was significantly vary (F (1,12) = 75.32, p<0.001) with the two pumpkin varieties. Production of C. montrouzieri was significantly higher with local pumpkins; C. moschata (t(14) = 6.11; p<0.05). The results indicated that, by starting the culture with 20 females and 15 males of C. montrouzieri, an average of 300.3 ± 41.8 and 180.4 ± 36.5 C. montrouzieri adults can be produced using two pumpkin varieties: C. moschata and C. maxima, respectively (surface area 1000 cm 2 ). Production of C. montrouzieri was significantly varied with the number of grooves appear on the surface area (1000 cm 2 ) of the pumpkin variety, C. maxima with the two host P. minor (R 2 = 0.9608, F (1,2) = 49.06, p<0.05) (Y = 7.326*X + 41.02) and P. viburni (R 2 = 0.9470, F (1,2) = 35.76, p<0.05) (Y = 15.14*X -53.22). Cost of production for a single C. montrouzieri, with the host P. minor reared on local pumpkin, C. moschata was found to be the lowest. It can be concluded that the selected mealybug species reared on C. moschata was more suitable for mass rearing the mealybug predator.
