Allantus luctifer (Hymenoptera: Tenthredinidae), a candidate agent for the biological control of Rumex spp.

The dock plant (Rumex spp.) is one of the most problematic pasture weeds worldwide. Allantus luctifer was selected as a potential biological control agent for Rumex spp. Continuous rearing of A. luctifer was carried out from 2005 to 2006, and its general biology is presented in this report. The preliminary host specificity test showed a promising result for using A. luctifer to control Rumex spp.

Mass emergence of a specialist sawfly species on unpalatable herbs under severe feeding pressure by sika deer

In recent years, the increase in sika deer populations has had a significant impact on forest ecosystems. Many studies have reported that this increase has led to the dominance of plants unpalatable to the deer; however, few studies have investigated the effects of this dominance on the specialist sawfly species that feed on the unpalatable plants. We observed the mass emergence of Aglaostigma amoorensis (Hymenoptera: Tenthredinidae), a rare specialist sawfly of the false helleborine Veratrum plants unpalatable to sika deer, in areas under severe feeding pressure by sika deer. An exponential increase in the number of emergent A. amoorensis adults was observed to occur with an increase in Veratrum album patch sizes. In addition, the increase in the A. amoorensis density had a negative effect on reproductive success of V. album. Our findings suggest that the relative abundance of specialist sawfly to the host‐plant abundance has changed for successive years after sika deer irruption.     

Effects of neem oil on feeding behaviour and development of the pear sawfly, Caliroa cerasi

Neem oil deterred feeding by pear sawfly, Caliroa cerasi L., larvae (Hymenoptera: Tenthredinidae), both in choice and in no-choice cherry leaf disk bioassays. Deterrence was greater in the choice tests, with 50% inhibition occurring at 0.49% aqueous neem oil compared with 1.11% in the no-choice tests. Antifeedant activity towards pear sawfly larvae is slightly less than has been observed for Lepidoptera, but is higher than deterrence to other insects such as aphids. Topical application of neem oil to sawfly larvae resulted in reduced feeding, increased mortality, and a trend towards slower development. Most larval mortality after neem treatment resulted from incomplete subsequent moults. The potential utilization of neem insecticides for control of pear sawfly in tree fruit pest management is discussed.
