In tasar silkworm culture the stem-boring jewel beetle Psiloptera fastuosa Fabr. (Buprestidae: Coleoptera) is considered as a major pest of tasar plant (Terminalia arjuna, Combretaceae) cultivation. The grubs of P. fastuosa often damage the Arjuna stem by causing dieback. Tyrophagus putrescentiae Schrank (Acari: Acaridae) infested buprestid eggs up to 15% and caused egg mortality up to 9%. The mite predation on the buprestid beetle is reported for the first time. The mite seeps the newly-laid egg-fluids causing the egg mortality suggesting that tasar plant stem-boring pest (P. fastuosa) can be partially controlled by the mite as a natural enemy.

The fungus gnat is a major pest of chive in China. Its control has been relied heavily on the application of clothianidin. Due to the intensive application, its control efficacy become reduced. The present study was intended to evaluate co-drenching of clothianidin with hexaflumuron on absorption and dissipation of clothianidin in chive plants and soils and determine the effect of such application on control efficacies. Chive production fields in Guangdong and Hubei Provinces were drenched with clothianidin alone and a mixture of clothianidin and hexaflumuron at low application rates. Concentrations of clothianidin in chive plants and soils were analyzed by HPLC. Results showed that co-application had higher control efficacies against the fungus gnat than clothianidin alone. The co-application enhanced clothianidin absorption and dissipation and extended the half-lives of clothianidin in chive. It was likely that hexaflumuron protected chive roots from larva damage, and healthy roots absorbed more clothianidin, resulting in the extension of the half-lives. Additionally, the terminal residues of clothianidin in chive after 14 days of application were lower than the maximum residue limit in chive set by the Codex Alimentarius Commission. This study for the first time documented that co-application of clothianidin and hexaflumuron improved chive plants in absorption and dissipation of clothianidin and enhanced fungus gnat control efficacies.

Population Suppression

Intercropping of aromatic plants provides an environmentally benign route to reducing pest damage in agroecosystems. However, the effect of intercropping on natural enemies, another element which may be vital to the success of an integrated pest management approach, varies in different intercropping systems. Rosemary, Rosmarinus officinalis L. (Lamiaceae), has been reported to be repellent to many insect species. In this study, the impact of sweet pepper/rosemary intercropping on pest population suppression was evaluated under greenhouse conditions and the effect of rosemary intercropping on natural enemy population dynamics was investigated. The results showed that intercropping rosemary with sweet pepper significantly reduced the population densities of three major pest species on sweet pepper, Frankliniella intonsa, Myzus persicae, and Bemisia tabaci, but did not affect the population densities of their natural enemies, the predatory bug, Orius sauteri, or parasitoid, Encarsia formosa. Significant pest population suppression with no adverse effect on released natural enemy populations in the sweet pepper/rosemary intercropping system suggests this could be an approach for integrated pest management of greenhouse-cultivated sweet pepper. Our results highlight the potential of the integration of alternative pest control strategies to optimize sustainable pest control.

Two wood-boring beetles are recorded for the first time in Greece. On late June 2001, the lepturine longicorn beetle Oxymirus cursor (L.) (Coleoptera: Cerambycidae) was found on Mt. Rodopi, and on early August 2012 the lucanid beetle Sinodendron cylindricum (L.) (Coleoptera: Lucanidae) was found on Mt. Falakron, in N. Greece. Images of both species and information on their distribution, ecology and biology, are presented.

Wood-boring bivalves of the families Teredinidae and Pholadidae are reported for the first time in Paraíba State, north-east Brazil. During one year, molluscs were collected from mangrove tree logs and from wood panels, along a salinity gradient. Four teredinid (Neoteredo reynei, Teredo bartschi, Nausitora fusticula, Bankia fimbriatula) and one pholad species (Martesia striata) were found.

Sangicoccus sp. nr. truncatispinus (Reyne) (Eriococcidae: Homoptera) is recorded for the first time as a major pest of coconut palms in the Philippines. It is   also the first record among the coconut growing areas in the world. It sucks the plant sap resulting to chlorosis of leaves. Furthermore, honeydew droplets exuded by the pest accumulated on upper leaf surfaces become substrate for sootymolds.   The severe infestation observed in late 1980’s already spread to 6 out of 8 municipalities of the southern second district of Palawan. Presently, crop losses are estimated to reach 53% of the nut yield. The prevailing easterly and westerly wind directions of 1-5 m/sec coupled with the dense manner of planting enabled first instar nymphs (crawlers) to spread to other palms. The long dry spell also favored the proliferation of Sangicoccus sp.bv.   Controlling the spread and outbreak of this pest seems to be difficult as it thrives on eleven alternate hosts. Ant attendance contributed to dispersal and protection from natural enemies. Moreover, field population of ten predatory species remained minimal. Possible strategies for its control are presented.

A New Species

Spruce bud scale, Physokermes piceae, develops on the genus Picea. Large colonies of this species are constantly present on Picea abies in green areas in the Belgrade territory, causing the drying of needles, branches and whole plants. Therefore, Ph. piceae is a significant spruce pest. Spruce scales attract many entomophagous insects able to reduce pest population. Parasitoid wasps Coccophagus lycimnia (Walk) (Aphelinidae) and Microterys lunatus (Dalm.) (Encyrtidae) were reared. Predators Exochomus quadripustulatus L., Scymnus abietis Paykull (Coccinellidae) and Anthribus nebulosus Forster (Anthribidae) were determined. Both species of ladybird were confirmed as predators of Ph. piceae for the first time in Serbia, while S. abietis is a new species for the fauna of Serbia. The most effective natural enemy of Ph. piceae was A. nebulosus, reducing populations by 68-80%.

The present investigation was carried out to study the “Eco friendly management of yellow stem borer, Scirpophaga incertulas (Walker) on paddy in western plain zone of Uttar Pradesh” in randomized block design with three replications and seven treatments at Crop Research Center, Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. The yellow stem borer, S. incertulas (Walker) was recorded as major pest. The incidence of S. incertulas (Walker) was recorded on the incidence of yellow stem borer Scirpophaga incertulas (Walker) showed that it was recorded on 26th standard week for the first time and continued till second week of November i.e. 46th standard week. The infestation of stem borer recorded as dead heart/ white ear head ranged from 0.85 to 15.25 per cent during the crop season i.e. Kharif 2017 and positive correlated with all the other weather parameters.

Three species of the genus Agrilus are described: A. bellamyi New Species from México, and A. braconoides New Species and A. lucindae New Species from Costa Rica. The male of Agrilus braconicoloratus Hespenheide from México is also described for the first time. These four species are hypothesized to be mimics of wasps in the family Braconidae, some of which are parasitic on wood-boring beetles. The mimicry complex is briefly described and discussed for Costa Rica and Panamá and probably involves both Mullerian and Batesian relationships with other beetles (Cerambycidae, Cleridae, and baridine Curculionidae) and Hymenoptera (Ichneumonidae and Mutillidae), predatory Heteroptera (Reduviidae), Diptera (Tipulidae), and other taxa. Examples are also given for South America and the Old World.

This is the first record of Phenacoccus solenopsis in Brazil, where it was found infesting tomato plants. The species Antonina graminis (Maskell), a common pest of Bermuda grass, and Dysmicoccus brevipes (Cockerell), a major pest of pineapple, also were encountered.
