Controlled atmosphere treatment for control of grape mealybug, Pseudococcus maritimus (Ehrhorn) (Hemiptera: Pseudococcidae), on harvested table grapes

  Controlled atmosphere (CA) treatments with ultralow oxygen (ULO) alone and in combinations with 50% carbon dioxide were studied to control grape mealybug, Pseudococcus maritimus (Ehrhorn) on harvested table grapes. Two ultralow oxygen levels, 30 and <0.01 µL L−1, were tested...

Rearing and Release of Aphelinus mali (Hald) (Hymenoptera: Aphelinidae), the Sole Parasitoid of Woolly Apple Eriosoma lanigerum (Hausmann) (Homoptera: Eriosomatidae) on Apple orchards in Ash-Shoubak

  Aphelinus mali (Hald) (Hymenoptera: Aphelinidae) is the sole parasitoid of woolly apple aphid (WAA), Eriosoma lanigerum (Hausmann) (Homoptera: Eriosomatidae). Five ratios of parasitoid to aphid colonies were tested to determine the suitable amount of the parasitoid that gives the highest...

Update on diamondback moth (Plutella xylostella) insecticide resistance and the vegetable brassica insecticide management strategy

The susceptibility of field populations of diamondback moth (DBM), Plutella xylostella, to lambda-cyhalothrin, methamidophos, spinosad and indoxacarb collected from the four major brassica-growing regions has been assessed approximately every 2 years from 1997 to 2008. Recent results indicate that...

Control of passionvine hopper and cicada eggs on kiwifruit canes with bifenthrin and a new superpenetrant adjuvant

A novel option for control of passionvine hopper (PVH, Scolypopa australis) and chorus cicada (Amphipsalta zelandica) on kiwifruit was investigated. This involved applying an insecticide to PVH and cicada egg sites in the dormant kiwifruit canopy, using a new type of adjuvant that allows sprays to...

Nematodes and Their Management

Plant parasitic nematodes are microscopic roundworms which live in the soil and attack the roots of plants. Crop production problems induced by nematodes therefore generally occur as a result of root dysfunction, reducing rooting volume and foraging and utilization efficiency of water and...

Insecticidal Activity of Tagetes erecta Extracts on Spodoptera frugiperda (Lepidoptera: Noctuidae)

The bioinsecticidal activity of organic extracts of Tagetes erecta L. (Asteraceae) was evaluated on neonate larvae of Spodoptera frugiperda J. E. Smith (Lepidoptera: Noctuidae) a major maize pest in the world. The acetone leaf extract (500 ppm) of T. erecta induced an antifeedant effect, causing a...

Insect Management on Organic Farms

Insect management presents a challenge to organic farmers. Insects are highly mobile and well adapted to farm production systems and pest control tactics. On organic farms, where the focus is on managing insects rather than eliminating them, success depends on learning about three kinds of...
