Pheromone‐trap monitoring system for sweet potato weevil (Coleoptera: Apionidae): Effects of pheromone source and purity

, 1992
Studies were conducted to develop a pheromone‐trap monitoring system for the sweet potato weevil, Cylas formicarius (Fabricius), in sweet potato, Ipomoea batatas (L.) Lam., fields in four states: Florida, Louisiana, North Carolina, and Texas. The present

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 ...

A Technique to assess the Longevity of the Pheromone (Ferrolure) used in Trapping the Date Red Palm Weevil Rhynchophorous ferrugineus Oliv.

Journal of Agricultural and Marine Sciences, 1999
The use of the aggregation pheromone, Ferrugineol (4-Methyl-5-Nonanol) has become an important component of the integrated Pest Management strategy currently adopted to trap the red palm weevil Rhynchophorous ferrugineus oliv., a pest which infects date ...

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.

Sex pheromone and visual trap interactions in mate location strategies and aggregation by host-alternating aphids in the field

, 1996
Field observations were made on the responses of males and gynoparae of three host-alternating aphid species, the blackberry-cereal aphid, Sitobion fragariae (Walker), the bird cherry-oat aphid, Rhopalosiphum padi (L.) and the damson-hop aphid, Phouodon ...

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.

EFFECT OF DIFFERENT TRAPS ON CAPTURES OF ADULT CORN ROOTWORM BEETLES (Diabrotica virgifera virgifera LeConte) IN EAST SLAVONIA [PDF]

Poljoprivreda, 2002
In 1995 the corn rootworm (Diabrotica virgifera virgifera LeConte) was detected for the first time in east Slavonia, Croatia. Its expansion to the west part has been very fast and from year to year populations of the pest are higher, especially when corn

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.

Improvement of Ips typographus catches in pheromone trap barriers by altering of sex assigned pheromone blends

Folia Oecologica, 2021
The present study was based on the idea of a pheromone trap barrier with alternating dispensers releasing different pheromone mixtures that affect males and females differently. We tested the possibility of increasing the catch efficacy of pheromone trap
