Water-soaked lesions on petal and leaf spots were observed on melampodium (
Melampodium paldosum), and inflorescence rot appeared on the smoke tree (
Cotinus coggygria) in Yamagata prefecture, Japan. The pathogenicity of each isolate obtained from diseased plants to host plants was demonstrated by artificial inoculation. These isolates were identified as
Botrytis cinerea on the basis of morphological and cultural characteristics and the sequence of the internal transcribed spacer regions of ribosomal DNA (rDNA-ITS) homology. Because no disease of these plants caused by
B. cinerea has ever been reported in Japan, we propose to name the disease gray mold (“haiiro-kabi-byo” in Japanese) of melampodium and smoke tree.

We examined the effect of exposure of eggs deposited on wheat seedlings to low temperature (4°C) on hatching in the sorghum plant bug,
Stenotus rubrovittatus. The number of newly hatched nymphs depended on the number of days in which the eggs were exposed to the low temperature. When the eggs were maintained at 4°C for 4 days, the number of nymphs decreased by half compared with the case in which the eggs were maintained at 25°C (i.e., control). On the other hand, the number of nymphs in the 2-day exposure group was 87% of that in the control. Furthermore, exposing the eggs to the low temperature did not affect the number of days until hatching. These results suggest that we can store eggs at 4°C within 2 days in order to synchronize the hatching.

The overwintering habit of
Pleuroptya ruralis was investigated in Fukushima Prefecture. Overwintering-generation larvae were found in the whole prefecture from April to May, 2007. The host plants of the larvae were
Boehmeria nivea var.
nipononivea,
B. nivea var.
nivea,
B. silvestrii,
B. spicata and
B. robusta. The overwintering sites of the larvae were under the host plants and cocoons were made from fallen leaves of these plants. The larvae overwintered mainly as 4th instars followed the 5th and 3rd instars.

We investigated daily catch data obtained using a water pan pheromone trap for the diamondback moth (DBM) from 1986 to 2007 in Morioka, Japan. We focus on the following indexes to define their annual change in spring, namely, the date of the first catch (FC), the first day of catching DBM for three or five consecutive days or more (3CD and 5CD) and the first day of double-figure DBM catch or more (DF). Although the FC had no remarkable tendency, there was a significant negative correlation between the other indexes, namely, 3CD, 5CD and DF, and years. It was shown that the recent date of DBM pheromone trap catch in spring was earlier than that twenty years ago.

The inhibitory effects of insecticides on the garden pea leafminer
Chromatomyia horticola (Goureau) on turnip leaves were examined under field conditions. Among of the 15 insecticides tested by spraying them on plants infested with leafminer larvae, tolfenpyrad was highly toxic on larvae of the insect and reduced the number of feeding traces of the larvae on the leaves. Spinosad, emamectin-benzoate, milbemectin, chlorfenapyr and cyromazine were also effective in controling leafminer populations, but their reduction effect on the number of feeding traces was weaker than that of tolfenpyrad. No such effects were observed on the plants sprayed with malathion, phenthoate, permethrin, thiamethoxam and acetamiprid.

Dendrocerus carpenteri (Curtis) (Megaspillidae) and
Asaphes suspensus (Nees) (Pteromalidae) are common aphid hyperparasitoids attacking primary parasitoids of economically important aphid pests. In this study, we investigated the developmental time and morphological characteristics of both species. Under laboratory conditions (20±1°C, 16L-8D), the developmental times of
D. carpenteri and
A. suspensus were 16 and 23 days, respectively. All immature stages could be distinguished between the two species by the shape, color, surface structure and behavior of the organisms.
