Abstract Crematogaster rogenhoferi (Hymenoptera: Formicidae), an omnivorous ant, is one of the dominant predatory natural enemies of a soft scale pest, Parasaissetia nigra Nietner (Homoptera: Coccidae), and can effectively control P. nigra populations in rubber forests. Olfaction plays a vital role in the process of predation. However, the information about the molecular mechanism of olfaction-evoked behaviour in C. rogenhoferi is limited. In this study, we conducted antennal transcriptome analysis to identify candidate olfactory genes. We obtained 53,892 unigenes, 16,185 of which were annotated. Based on annotations, we identified 49 unigenes related to chemoreception, including four odourant-binding proteins, three chemosensory proteins, 37 odourant receptors, two odourant ionotropic receptors and three sensory neuron membrane proteins. This is the first report on the molecular basis of the chemosensory system of C. rogenhoferi. The findings provide a basis for elucidating the molecular mechanisms of the olfactory-related behaviours of C. rogenhoferi, which would facilitate a better application of C. rogenhoferi as a biological control agent.

About 953000 individuals of the cosmopolitan parasitoid,Coccophagus scutellaris(Dalman) (Hymenoptera: Aphelinidae), were released and evaluated during 2009-2010 for the control of the following soft scale insects (Hemiptera: Coccidae) infesting the following economic crops in Egypt:Ceroplastes ruscion citrus in Beni Seuf,Ceroplastes floridensisComstock on citrus in Gharbiya,Coccus hesperidumL. on guava in Giza,Pulvinaria floccifera(Westwood) on mango in Sharqiya,Pulvinaria psidiiMaskell on mango in Ismailia,Saissetia coffeae(Walker) on olive in Marsa Matruh, andSaissetia oleae(Oliver) on olive in the Northern Coast. The population ofC. scutellarisshowed a significant correlation with the build up of the population of the soft scale insects population in all of the release sites studied. The maximum rate of parasitism of the other species of parasitoids associated with soft scale insects at the release sites decreased after the release ofC. scutellaris.

Fungal Entomopathogen

A new species of Lecanicillium was found associated with the soft scale insect Pulvinaria caballeroramosae (Coccidae), an important pest of Ficus soatensis (Moraceae) in Bogotá, Colombia. Lecanicillium sabanense sp. nov. differs from similar Lecanicillium spp. mainly in the size of the conidia, in the vertical arrangement of phialides on the host, and in the tomentose mycelium that sparsely covers the cuticle of the host. Phylogenetic analyses using ITS, SSU, LSU, TEF, RPB1, and RPB2 also confirmed the distinctness of this new species. Fungal epizootics were found on female soft scale insects, which may have implications for biological control in the forestry program of the city. The ecology of the fungus as well as its potential use as a biological control agent are further discussed.
