The interactions between the lacewing Ceraeochrysa claveri (Navás) (Neuroptera: Chrysopidae) larva and the coconut mealybug Nipaecoccus nipae (Maskell) (Hemiptera: Pseudococcidae) were recorded. The third-instar lacewing larva constructed a dorsal packet using mealybug wax from both male pupal cases and the bodies of adult females. Surprisingly, live nymphs were also frequently placed into the dorsal packet. Prey mealybugs were discarded and not incorporated into the packet after consumption. When disturbed, adult female mealybugs reflex bled from their dorsal ostioles, contacting the mouthparts of the lacewing. The lacewing quickly retreated to clean the mouthparts on the substrate, providing further evidence that ostiolar fluids act as a defense mechanism for mealybugs. Despite repeatedly contacting the ostiolar fluid, the lacewing pupated and eclosed successfully. Macro video footage of dorsal packet construction and ostiolar reflex bleeding is included. This is the first report of C. claveri preying on N. nipae, the first evidence of C. claveri using mealybug wax to construct the dorsal packet, and the first account of reflex bleeding via the dorsal ostioles to deter predators in N. nipae.

Paratelenomus saccharalis (Dodd) (Hymenoptera: Scelionidae) parasitizing Brachyplatys subaeneus (Westwood) eggs is reported for the first time for Panama. Brachyplatys subaeneus is an invasive species from Asia and is regarded as an important agricultural pest in the Americas.

Korean encyrtids (Hymenoptera: Encyrtidae) associated with scale insects (Hemiptera: Coccomorpha)
(2019)
Scale insects (Hemiptera: Coccomorpha) are sap-sucking plant parasites and economically important pests on agricultural and horticultural crops. Scale insects are often difficult to control since their body is protected by a wax cover. Parasitic wasps that live and develop in scale insects are important natural enemies and effective biological control agents of pest scale insects. Chalcid wasps of the family Encyrtidae (Hymenoptera: Chalcidoidea) comprise the largest group of parasitoids of scale insects, followed by the family Aphelinidae. Here, an updated list of all thirty-six species of encyrtids in twenty-three genera that have been identified or reported from South Korea is provided, along with a dichotomous taxonomic key to separate them.

A remarkable new species of Poecilocloeus (Orthoptera: Acrididae: Proctolabinae) found damaging coffee plantations in the Western Andes of Colombia is described and named P. coffeaphilus n. sp. This new species is part of a distinct and colorful group of Proctolabinae grasshoppers, with most species found at low altitudes in the rainforest of the Amazon basin. In contrast, the new species is found at elevations of 1600 to 1800 m in the canopy of dense cloud forests, in the southwestern part of the department of Antioquia (Western Cordillera, Colombian Andes). Information about the natural history, behavior, natural enemies and control strategies in coffee plantations is given for this new species of masked grasshopper. A key to the Neotropical species of the fruticolus species group is presented.

In recent years, populations of the Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), have increased in rural citrus orchards and urban backyard gardens. In order to fi nd biological control options for D. citri, a search for natural enemies was conducted in the department of Valle del Cauca, Colombia. The collections were carried out in citrus orchards in rural areas and house gardens and street trees in urban areas.
Natural enemies were collected from D. citri found on Citrus spp. and Murraya paniculata (L.) Jack (Rutaceae). A total of 16 species of natural enemies of D. citri distributed in six families in fi ve orders are reported from Colombia.
Herein we provide an updated list of 95 species of arthropod (arachnids and insects) natural enemies of D. citri distributed in nine orders and 23 families recorded worldwide.

The Colombian fluted scale (CFS), Crypticerya multicicatrices Kondo & Unruh (Hemiptera: Monophlebidae) is a polyphagous scale insect which affects about 100 species of plants. Between 2010–2013, the species was reported as an invasive pest on the islands of San Andres and Old Providence, Colombian territory in the Caribbean sea.
Currently, populations of the CFS also have increased in the city of Cali, Valle del Cauca State, mainland Colombia, affecting different host plants, especially leguminous trees such as Caesalpinia peltophoroides Benth., Pithecellobium dulce (Roxb.) Benth., P. saman (Jacq.) Benth. (Fabaceae) and mango, Mangifera indica L. (Anacardiaceae). With the aim of searching for natural enemies to control the CFS, field studies were conducted in the city of Cali between February 2013 and October 2014. As a result of this study, two species of lady beetles were found feeding on CFS, i.e., Anovia punica Gordon and Rodolia cardinalis (Mulsant) (Coleoptera: Coccinellidae). This is the first record of R. cardinalis preying on CFS.

Specimens of Megacopta cribraria (Fabricius) were collected in northern Georgia in late October 2009, where they were invading homes in large numbers. This is the first known occurrence of this species and the family Plataspidae in the New World. Megacopta cribraria was previously known from Asia and Australia. A key is provided to separate Plataspidae from other families of Pentatomoidea in America North of Mexico. A diagnosis and figures are provided to facilitate recognition of M. cribraria. Reported host plants and other aspects of the biology of this species are reviewed. Megacopta cribraria is considered a pest of numerous legumes in Asia, has the potential to provide biological control of kudzu, Pueraria montana var. lobata (Willd.) Ohwi, (Fabaceae) and likely will continue to be a household pest in the vicinity of kudzu fields as well as become a pest of North American legume crops.
