The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

Insect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

Edges as ecological filters: Asymmetrical orientation‐specific arthropod activity across forest boundaries

Insect Science, EarlyView.
Moderate retention forestry creates structurally sharp forest edges that act as ecological filters, shaping orientation‐specific activity of ground‐dwelling arthropods. Using drift‐fence pitfall traps, we show that activity aligned with ecotones is more frequent than activity across forest–clearcut boundaries, particularly among detritivores.

Bounds on Absolute Gypsy Moth (Lymantria dispar dispar) (Lepidoptera: Erebidae) Population Density as Derived from Counts in Single Milk Carton Traps

Insects, 2020
Estimates of absolute pest population density are critical to pest management programs but have been difficult to obtain from capture numbers in pheromone-baited monitoring traps.

Ozone‐driven degradation of sex pheromone in Plutella xylostella: Implications for reproductive communication and mating success

Insect Science, EarlyView.
In this study, we examined whether realistic ozone concentrations can interfere with sexual communication in the insect pest Plutella xylostella, the diamondback moth. Ozone exposure caused a degradation of pheromone components, leading to significant changes in blend composition and component ratios.

Sampling gravid Culex quinquefasciatus (Diptera: Culicidae) in Tanzania with traps baited with synthetic oviposition pheromone and grass infusions

, 2000
The effectiveness of traps baited with (5R,6S)-6-acetoxy-5-hexadecanolide (the synthetic oviposition pheromone) and grass infusions in sampling a population of gravid Culex quinquefasciatus Say was conducted in Muheza, Northeast Tanzania.

Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived bacterial semiochemicals

Insect Science, EarlyView.
Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived airborne semiochemicals. Egg‐borne bacterial symbionts, and Serratia marcescens in particular, produce odorants which attract gravid female flies and elicit oviposition.

Mothbox and Mothbot: Automated light trap and data processing system for scalable insect monitoring

Methods in Ecology and Evolution, EarlyView.
Abstract Insects represent the most diverse group of organisms on Earth and comprise the majority of known species; yet they are seldom accounted for in large‐scale biodiversity monitoring systems and conservation planning. We have developed the Mothbox—an open source automated light trap that makes insect monitoring accessible to non‐specialists and ...

Attraction of Phoracantha mastersi (Coloeptera: Cerambycidae) to copulation‐associated olfactory stimuli

Agricultural and Forest Entomology, EarlyView.
Damage caused by Phoracantha mastersi larvae are the primary cause of forest decline in Australia's subalpine forests. Behaviour of male adult beetles was tested in response to a suite of commercial semiochemicals and conspecifics engaged in active copulation within a Y‐maze.
