Summary: Vine weevil is a significant economic pest, and the development of effective monitoring systems is crucial. This study found that adult vine weevils prefer dark, tall refuges with entrances around the base. These findings provide important insights for the design of improved monitoring tools.

Summary: This article discusses the importance of the vine weevil pest and the application of biological controls. The authors argue that simply switching from synthetic insecticides to biological controls is a key factor in the continued importance of this pest. Through research on vine weevil biology and ecology, improved integrated pest management programs can be developed.

Summary: This study successfully developed a fast and sensitive detection protocol for Naupactus cervinus and Naupactus xanthographus, achieving 100% accuracy in a panel of 480 test samples. The protocol is based on multiplex TaqMan Real-time polymerase chain reaction and allows for species-specific detection with high sensitivity.

Summary: Since Darwin proposed two opposing hypotheses, preadaptation and competition-relatedness hypotheses, to explain the establishment of species in areas outside their native ranges, many studies have focused on understanding the relative importance of each hypothesis. In this study, we used beetle communities in laurel forests of the Canary Islands to evaluate the support for Darwin's hypotheses within arthropods for the first time. Our results suggest that species preadaptation plays a stronger role than resource competition, and highlight a lack of knowledge regarding whether arthropod species are native or introduced, which we refer to as the Humboldtean shortfall. We suggest that future studies using arthropods should incorporate DNA barcode sequencing to address this issue.

Summary: Hazelnut weevils can cause various types of damage to hazelnuts, including dropped nutlets, belted nuts, and blank nuts. Both the feeding activities of the weevils and the oviposition punctures can lead to embryo abortions. The major damages occur during kernel growth and when the hazelnut shell is almost fully developed.

Summary: The study tested the use of bottle traps baited with apple cider vinegar and other food products to capture exotic and invasive beetles around Malpensa Airport, Italy, with successful results. The apple cider vinegar was particularly effective in attracting the invasive Popillia japonica. Controlling the exposure time of traps can significantly reduce the catch of native species.

Summary: This study analyzes the ladybird beetle fauna of La Palma, one of the western islands of the Canary Islands. The survey recorded 26 species, including 7 new to La Palma and 2 new to the Canary Islands. The study confirms the frequent colonization of exotic ladybird species in the Canary Islands.

Summary: Research on the guava weevil confirmed the bioecology of the insect and found differences in penetration time in different soil types, with most larvae abandoning fruits during the day and most adults emerging in the afternoon. The average time period from larval penetration to adult emergence was approximately nine months.

Summary: This article describes five new species of Anisandrus found in Thailand, and also reports the first record of Anisandrus carinensis in Thailand while removing A. apicalis from the Thai fauna. With the addition of these newly described and recorded species, the diversity of Anisandrus is increased to 40 species, with 11 occurring in Thailand. A synoptic list and key to the Anisandrus species in Thailand are provided.

Summary: New fossil species of the genus Diapus are described in Miocene amber from Ethiopia and Zhangpu, China. The large number of Diapus specimens found in Zhangpu amber supports the paleoenvironmental reconstruction of a megathermal seasonal rainforest. The discovery of these new species suggests that the diversification of the Platypodinae genus Diapus, potentially associated with angiosperms, may have started in the Cretaceous and increased in diversity during the Miocene. These specimens represent the first record of Diapus preserved in amber.

Summary: This article redescribes Otiorhynchus tomentifer and proposes its new placement in the subgenus Pseudocryphiphorus. The previous placement of O. tomentifer in the subgenus Postaremus is rejected. Additionally, comprehensive morphological data on the genitalia of O. tomentifer and the type species of the subgenus Postaremus, O. nodosus, are provided.

Summary: Invasive non-native predators can negatively impact native species, but some native species can survive by using pre-existing antipredator strategies or evolving defenses against invasive predators. The American bullfrog is an intentionally introduced predator that has caused impacts through direct predation on native animals. However, it has been found that the invasive bullfrog attacks and consumes a native bombardier beetle species in Japan, raising questions about the effectiveness of the beetle's defense mechanism. This study investigated the behavioral responses of bullfrog juveniles to the bombardier beetles and found that the bombing defense was crucial for the beetles' successful defense against the invasive bullfrogs.

Summary: This article describes various methods for collecting and preserving bark and ambrosia beetles, including collecting tools, recording data, and step-by-step beetle extraction techniques. It also elaborates on trapping techniques, tools, attractants, and beetle preservation. The key rule for manual collecting is to separate the wood or bark from the beetle gently and systematically, instead of trying to pry the insect out. The main rule for trapping is to use attractants and traps that reflect the ecology of the targeted beetle species.

Summary: The red palm weevil is a notorious pest for palm trees worldwide, and entomopathogenic nematodes are considered the most effective biocontrol agents. The study showed that Steinernema carpocapsae and Heterorhabditis bacteriophora were the most effective nematodes against different developmental stages of the red palm weevil. Larvae were found to be the most susceptible to infection, and S. carpocapsae caused 100% mortality in the 6th instar larvae. These findings suggest that S. carpocapsae and H. bacteriophora could be used for sustainable management of the red palm weevil.
