Summary: Nonrandom mating was observed between the South strain (SS) and North strain (NS) of Euschistus heros, with SS individuals showing a preference for mating with their own strain. Pronotum width was found to be positively associated with mating choice, suggesting size-assortative mating in this species. Reciprocal crosses between strains yielded similar reproductive outputs, indicating similar fitness of hybrid pure strains.

Summary: The Neotropical brown stink bug is a major soybean pest in Brazil, controlled mainly by insecticides of the neonicotinoid class. A new ingestion bioassay method using liquid diet encapsulation shows promise for detecting and monitoring resistance of E. heros populations to these insecticides. High variations in susceptibility to insecticides were detected among populations, motivating the development of diagnostic concentrations based on LC99 levels.

Summary: The brown stink bug, Euschistus heros, is a common pest in Brazilian soybean crops, causing significant yield losses. Chemical control is usually used, but biological control with parasitoids Ooencyrtus submetallicus and Telenomus podisi is becoming more popular. This study evaluated the development of the parasitoids at different temperatures and estimated the number of annual generations in seven soybean-producing regions in Brazil. The results showed that the parasitoids have a higher ability to parasitize and develop in stink bug eggs compared to the host.

Summary: Insects, such as the brown marmorated stink bug and its egg parasitoid, use olfaction to interact with their host plants, with findings showing preferences of the stink bug nymphs for apple and peach odors and the parasitoid for specific compound combinations.

Summary: This study evaluated the response of soybean genotypes to different patterns of E. heros infestation. The genotypes 'IAC-100' and 'Conquista' exhibited tolerance to the stink bug, and oxidative enzymes may be associated with the physiological response of the genotypes.

Summary: This study evaluated the biological characteristics of the brown stink bug under constant and fluctuating temperatures for three successive generations. It found that temperature affected the bug's development and reproduction. Increasing temperature reduced the duration of the nymphal stage, but some temperatures prevented adult reproduction. These findings are important for mass-rearing programs and field management of the stink bug.

Summary: This study analyzed the interactions between two parasitoid species in the field and their effects on pest control. It found that T. podisi had a greater ability to discriminate eggs previously parasitized by conspecifics, while the presence of T. basalis reduced emergence rates. Competition changed the emergence pattern of the parasitoid offspring, leading to a decoupling of the host-parasitoid dynamics synchrony and reducing the effectiveness of long-term pest control.

Summary: This study used electropenetrography (EPG) to characterize the stylet penetration behaviors of nymphs of the Neotropical brown stink bug. The findings revealed that the nymphs exploit the xylem vessels and the seed tegument or endosperm. The study identified four phases of behavior: nonfeeding, pathway, salivation, and ingestion. The study also found differences in waveform events and total duration among nymph instars, providing important insights for pest management programs.

Summary: Insect pollination is a vital process for the natural ecosystem and crop reproduction. Bumblebees, especially Bombus terrestris, are widely used pollinators for crops such as tomato. The efficiency of bee pollination is influenced by various factors, including bee species, plant nutrition, and herbivores like Bemisia tabaci. This study found that B. terrestris preferred tomato plants damaged by B. tabaci, and identified specific plant volatiles induced by B. tabaci that significantly attracted B. terrestris.

Summary: The study evaluated the impact of insecticides used on soybean seeds on the population dynamics of Euschistus heros, commonly known as the Neotropical brown stink bug. The results showed that insecticide treatments did not affect the population dynamics of E. heros during the cycles and conditions of the soybean crops studied, with no residual effects observed.

Summary: This study investigated the differences in volatiles released by alligatorweed plants under different treatments. The results showed that alligatorweed plants can be induced to release volatiles by different stages of alligatorweed beetles, and the released volatiles differ quantitatively and qualitatively.

Summary: The study reveals that the parasitoid species Bracon vulgaris can recognize and respond to the volatiles emitted by cotton plants infested by the pest Anthonomus grandis. Certain compounds, such as beta-myrcene and (E)-ocimene, may play a key role in attracting the parasitoid wasps in their host foraging behavior. This highlights the importance of terpenoids in cotton indirect defense and sheds light on the role of minor plant volatiles in insect pest control.

Summary: Research has shown that sustainable agricultural crop protection can be achieved through chemical ecology studies and the use of companion plants. Understanding how herbivore-induced plant volatiles regulate multifaceted defense responses can lead to the development of new crop protection strategies. Studying the interactions between companion plants, herbivores, and natural enemies in the field can enhance knowledge and contribute to the development of more efficient and sustainable pest management strategies.

Summary: Fruit flies deposit a host-marking pheromone after oviposition to minimize overexploitation of hosts. In laboratory experiments, the faeces extract from mated female A. fraterculus was found to reduce fruit infestation by both conspecifics and heterospecifics. The faeces extract from mated female fruit flies contained higher amounts of specific compounds compared to that of mated males.

Summary: This study evaluated the potential of C. cajan plants as trap crops for D. melacanthus. The results showed that D. melacanthus females prefer to oviposit on C. cajan pods and are attracted by volatiles emitted by reproductive C. cajan plants. In addition, the offspring of D. melacanthus cannot survive on C. cajan pods.

Summary: Plants respond to herbivore injury by emitting specific volatiles that attract the enemies of herbivores. This study evaluated whether maize plants can recognize damage from a stink bug and found that while the stink bug does not use plant volatiles as host location cues, feeding by the stink bug activates maize indirect defense, inducing emission of attractant volatiles for the herbivore's enemy.

Summary: The aim of this study was to evaluate the effect of volatile organic compounds (VOCs) emitted by Trichoderma azevedoi CEN1241 in different growth periods on the severity of white mold in common bean. Chemical analysis revealed that T. azevedoi CEN1241 produced 37 VOCs, which were shown to be related to the ability of the biocontrol agent to suppress Sclerotinia sclerotiorum. The results demonstrated that T. azevedoi CEN1241 VOCs reduced the size of S. sclerotiorum lesions in vitro and decreased disease severity in a greenhouse, indicating the potential of volatile compounds as a control strategy for white mold in bean plants.

Summary: This study evaluated the effects of footprints of Tenuisvalvae notata and Cryptolaemus montrouzieri lady beetles on their own and each other's foraging behavior and predatory potential. The results showed that both species can recognize each other's footprints and have different reactions to them. Chemical analysis revealed that the composition of footprint extracts is species- and sex-specific. This is the first report on the effects of footprints on the behavior of these species.
