Other claims from this paper (5)

Observation Bark harvesting methods did not change diameter or tree height growth rates.
Observation Wider bark strips reduced bark recovery rate.
Observation Wider bark strips increased rates of insect attack and disease.
Recommendation The authors recommend harvesting bark in strips 2 cm wide and 2 m long with 4 cm spacing.
Recommendation The authors conclude D. brasiliensis has high potential for sustainable management of natural populations.

Comparative Studies On Effects Of Garlic (Allium Sativum) And Ginger (Zingiber Officinale) Extracts On Cowpea Insects Pest Attack.

Umesi Ndubuisi; B Nnah Maxwell 2010

Other claims from this paper (4)

Intervention effect Garlic and ginger extracts decreased leaf damage on cowpea.
Intervention effect Increasing plant extract levels increased the cowpea insect pest population.
Intervention effect Plant extract treatments increased cowpea weight per 100 seeds and grain yield significantly.
Mechanism The authors interpret the rise in pest incidence as showing that the extracts are attractive and antifeedant to insects.

Variation in attack by the mahogany shoot borer, Hypsipyla grandella (Lepidoptera: Pyralidae), in relation to host growth and phenology

A.C. Newton; J.P. Cornelius; J.F. Mesén; et al. Bulletin of Entomological Research 1998. doi:10.1017/s0007485300025931

Other claims from this paper (15)

Observation Cedrela leaf phenology varied over time and at minimum 51% of trees retained leaves in a dry period.
Observation The minimum proportion of foliated Swietenia trees was 87%.
Observation No Swietenia shoot borer attacks occurred before week 50.
Observation Initial Cedrela attacks occurred in week 6.
Observation By week 84, 74% of Cedrela trees had been attacked.
Observation By week 84, 77% of Swietenia trees had been attacked.
Association Attack peaks in both tree species coincided with new shoot production.
Observation Both tree species showed pronounced spatial variation in attack.
Association Cedrela attacks per block were negatively correlated with available calcium at week 12.
Association Cedrela height growth was positively correlated with available phosphate.
Observation Height to first damaging attack varied significantly in both species.
Observation Only 6% of Cedrela remained undamaged to 3 m by the end of observations.
Observation Only 0.4% of Swietenia remained undamaged to 3 m by the end of observations.
Recommendation Shoot borer control should account for seasonal attack and host phenology.
Recommendation Manipulating soil nutrient status may form part of integrated shoot borer management.
