Stink bugs are among the major pests of soybean [Glycine max (L.) Merrill] worldwide. Piezodorus guildinii [Westwood] (Hemiptera: Pentatomidae) is one of the predominant pest species, causing more severe damage in many regions than other stink bugs. Its attack reduces yield and quality of the beans. Plant resistance is a valuable strategy in integrated pest management that can reduce insect populations below economic injury level. Here, we report the resistance of 17 soybean entries to P. guildinii. PI 229358, PI 274454, L1-1-01, “IAC 19,” PI 171451, PI 227687, “IAC 100,” IAC 78-2318, PI 274453, and IAC 74-2832 caused high nymphal mortality (greater than 90 %), indicating the expression of antibiosis. “IAC 100,” IAC 74-2832, PI 274453, and “IAC 24” also increased the length of the nymphal stage of P. guildinii, showing the same mechanism of resistance. Our findings may be useful for breeding programs that focus on the resistance of soybeans to insects. 相似文献

Harlequin bug (Murgantia histrionica) is an important pest of cole crops in the USA. The adults and nymphs feed on aboveground plant tissues by sucking cell contents and can seriously damage the host. Current insect control measures on cole crops target mainly lepidopteran pests, and the insecticides generally used do not control harlequin bug, so alternative management practices need to be explored. Previous research has established the existence of a male-produced pheromone attractive to both sexes and nymphs of M. histrionica. In this work, two systems of marking bugs were tested to verify if the mark affected fitness traits such as survival and host location. In a second phase, marked individuals were placed on trap host plants baited with synthetic pheromone lures to test whether migration rates were related to M. histrionica density on the trap plants and the presence of the attractants. Neither marking system affected the survival or orientation of the subjects compared to unmarked individuals. The pheromone lures significantly increased the attractiveness of the trap plants, but did not increase the retention time of the plants compared to unbaited plants. Emigration from the trap plants showed a constant rate and seemed unrelated to bug density on the plants. However, a mean peak density of ca. 36 bugs/plant was calculated. Beyond this number, density tended to decrease. These successful marking methods and retention time models support development of M. histrionica management with trap crops, by providing tentative control thresholds and decision rules. 相似文献

From the beginning of this century, tachinid flies have been involved in many operations of applied biological control against different insect pests. A review is done about utilization of Tachinidae all over the world. These parasitoid insects were used by inoculative, augmentative or inundative releases. Most of the operations were accomplished in the nearctic and neotropical regions. Sometimes great successes were obtained especially in North America and in tropical areas. Success or failure of release processes may be explained by different ways shortly analysed. 相似文献

A poorly known chrysomelid beetle, Chrysolina fastuosa (Scopoli) has been found in a strikingly great number on black horehound (Ballota nigra L.), a soft caulescent plant belonging to the Lamiaceae family. B. nigra can be found from April to August commonly on roadsides, along walls or at the border of gardens and orchards in Hungary
and continental Europe. It can be called a minor weed. The glistering tiny adults that feed voraciously on leaves cause apparently
significant damage. The subsequent investigation, which focuses on the number of feeding individuals and the loss of plant
tissue, showed 1–24 beetles on a plant and the consumed leave surface which amounted to 8–94%. The repeated damage assessment,
a week later showed a significantly unimportant increase in the number of individuals but a significant 20–31% increase in
the plant surface loss. According to the literature, Ch. fastuosa has been found in association with other Labiatae plants such as Galeopsis pubescens Besser, Lamium album L. and Urtica dioica L. (Urticaceae). Thus, considering its efficiency mentioned above, it could be used to augment and maintain its populations
as a biological control agent for these weeds. However, taking into consideration the growing importance of the production
of medicinal plants among which Lamiaceae species are numerous, Ch. fastuosa can cause damage that cannot be neglected. 相似文献

Parasitoids’ efficiency in controlling pests depends not only on their ability to parasitize their hosts but also on how much
they are adapted to climatic conditions (notably temperature) of the area where they are planned to be released. In addition,
the optimal conditions for production of parasitoids used for inundative releases like Trichogramma spp. may also vary largely as a function of strains. Using the parasitoid Trichogramma cacoeciae Marchal as biological model, we studied how temperature affects important parasitoid efficiency-related biological traits
under laboratory conditions. Emergence, mortality rates and fecundity of two strains of T. cacoeciae, one originating from France (Alsace) and the other one from Tunisia (Degache), were compared at constant temperatures of
15, 20, 25 and 30°C. The parasitoids of the French strain showed highest fecundity at 25°C with wasps that had been reared
at 20 or 25°C. The Tunisian strain showed the highest fecundity at 25°C, but only when wasps were previously reared at 25
or 30°C. For both strains, the highest mortality occurred among wasps that had laid eggs at 30°C. Emergence rates were relatively
high at all temperatures, although the French strain did better at 15–25°C and the Tunisian one at 20–30°C. Because of the
differences in biological traits of these two T.
cacoeciae strains in relation to the temperature, a judicious choice must be made among the various strains when using this species
in biological control programs. 相似文献

The parasitoids (Hymenoptera, Braconidae, Aphidiinae) of the cowpea aphid, Aphis craccivora Koch, were investigated throughout two far distant provinces, Tehran and Sistan-Baluchestan. Colonies of the cowpea aphid
were collected from different host plants and reared under laboratory conditions until the parasitoids emerged. The aphids
were parasitized by an expected range of parasitoids. The species were Aphidius colemani Viereck, Lysiphlebus fabarum (Marshall), Lysiphlebus confusus Tremblay and Eady, Lysiphlebus testaceipes (Cresson), Binodoxys acalephae (Marshall), Binodoxys angelicae (Haliday), Praon volucre (Haliday) and Ephedrus persicae Froggatt. L. testaceipes is reported here for the first time in Iran. The most common species was L. fabarum followed by B. acalephae and L. confusus. A key is provided for identification and host plant associations are considered. 相似文献

The effect of various constant temperatures on survival, development, and adult longevity of Venturia canescens Gravenhorst (Hymenoptera: Ichneumonidae) parasitizing larvae of Plodia interpunctella Hübner (Lepidoptera: Pyralidae) was studied under laboratory conditions. The following temperatures were tested: 15, 17.5,
20, 22.5, 25, 27.5, 30, and 32.5°C. The percentage of parasitoids that completed development at each temperature as well as
the days needed for the emergence of the parasitoid’s pupa and adult eclosion was measured. Adult longevity was estimated
under the same conditions. Survival of V. canescens was significantly higher at 25 and 27.5°C compared to 17.5, 20, 30, and 32.5°C. No individual of V. canescens managed to complete development at 15°C. Overall, developmental time decreased significantly with increasing temperature
within the range of 17.5–27.5°C. The lowest developmental time was observed at 27.5°C while the highest at 17.5°C. Upper and
lower threshold temperatures for total development were estimated at 36.2 and 13.2°C, respectively. Optimum temperature for
development and thermal constant were 30.6°C and 312.5 degree days, respectively. Adult longevity was also affected by temperature,
as it was significantly reduced at higher temperatures compared to the lower ones. This information would be useful in determining
the potential of using V. canescens as a biological agent in IPM programs, by optimizing mass rearing and release techniques of the parasitoid. 相似文献
