Do So

Abstract Due to its wide host range and low reproductive potential, colonization rates of P. mathias are rather low compared to more specialized rice pests. Those ovipositing adults that do arrive do so after significant numbers of natural enemies have built up; this helps to explain the normally low pest status of P. mathias.

First Time

The notoriously destructive and invasive soft scale, Ceroplastes cirripediformis Comstock (Hemiptera: Coccomorpha: Coccidae), is recorded for the first time from India. The scale is redescribed to facilitate its identification and information on its host range, natural enemies and distribution is provided. An identification key to the Indian species in this genus is given. Management options in the event of an outbreak are discussed briefly. The establishment of this scale insect warrants special attention in India as it is a potentially damaging plant pest and has a broad host range across many plant families.

Chrysanthemum stunt viroid (CSVd), a noncoding RNA, is known to cause chrysanthemum stunt disease, which affects the yield of flowers. To gain insights into CSVd replication, infection, and the reasons for the spreading of CSVd disease in chrysanthemum plants, we prepared linear CSVd RNA and analyzed its ability to cause disease in chrysanthemum plants. We found that linear CSVd replicated as efficiently as CSVd RNA isolated from the infected chrysanthemum plants. Additionally, the linear CSVd RNA was evaluated for its ability to infect other plants as well, which revealed that CSVd has a wide host range for its replication. Importantly, the CSVd isolated from these hosts is infectious to chrysanthemum plants, and thus potentially contributes to the spreading of the disease to chrysanthemum plants.

Considerable Damage

The safflower fly, Acanthiophilus helianthi Rossi, 1794 (Diptera: Tephritidae) is one of the most important pests of safflower in Iran. Losses caused by larval feeding leads to disrupted plant activities, reduction in flower buds, and, ultimately, to decreased quality and quantity of crop. An investigation was made from March 2008 to August 2009 in Gachsaran and Yasooj to record the pest status of safflower and their natural enemies. A total of twenty arthropods were recorded as pests of safflower. Out of 25 farms surveyed, only seven had the incidence of pest attack. Among the pests, Safflower fly and Silver ‐ Y‐ moth were found to cause considerable damage to the safflower plants, while others were not at economic levels. Among the natural enemies, parasitoids like Bracon hebetor, Bracon luteator, Colotrechnus viridis, Antistrophoplex conthurnatus, Microdontomenus annulatus, Ormyrus orientalis, Eurytoma acroptilae, Pronotalia carlinarum, Pteromalus sp. and Isocolus tinctorious were found to be associated with the pests of safflower.

And Control

<i>Echinothrips americanus</i> Morgan, 1913, is one of the pest species that expanded their area of distribution in a relatively short time. Being native to the eastern parts of North America, its first European interception was recorded in 1989. Since then it has invaded greenhouses in most European countries, including Slovakia, where it was first recorded in inspected material at the Botanical garden in Košice. As a polyphagous thrips with a wide host range it may induce damage mainly on ornamentals, although if low in numbers it can be easily overlooked. The species is a suitable example where preventive steps against its spread have not been sufficient enough which, therefore, demands further monitoring. Remarks on morphology, identification, economical importance and control are also given.

Efficacy Assessment

Based on the reconsideration of traditional criteria for assessing the efficacy of natural enemies, the screening of coccinellids for preventative control of aphids was conducted. The result suggests that there is no causation between the female size (weight) and the reproductive potential of the tested species. Considering that size does not matter in preventative releases, it is more cost-effective to produce small lady beetles. Essential and non-essential ecological knowledge for the efficacy assessment is discussed.
