Title:
Golden Apple Snail and thier management
Description:

Golden apple snail (GAS, Pomacea sp.) is native to South America and was introduced to Asia, first in Taiwan in 1979-1980.  GAS was introduced to Cambodia in 1992 by refugees returning from Cambodia-Thailand camps.  In 1995, GAS had been observed being raised and sold in Phnom Penh and presented in at least nine provinces: Kampong Chhnang, Kampong Cham, Siem Reap, Pursat, Kampong Speu, Takeo, Prey Veng and Svay Rieng.  Recently, GASs are spreading in the rice fields in almost all provinces and municipalities in Cambodia.

Although in 1995, the Cambodia-IRRI-Australia Project (CAIP) alerted that GAS would be a new destructive rice pest in Cambodia, but since 1992 until 2009, GAS population in the rice fields has not caused any significant or remarkable rice plant losses.

Since 2010, the situation has been changed with many farmers reported and remarkably observed rice young plants losses due to damage by GAS.  To overcome this problem and after confirmed experimental results on effective Mulucide 6GB, CARDI is publishing a Farmer Notes of golden apple snail and its management with emphasizes on the differences between GAS and Cambodian native snail (Pila sp.), life cycle of GAS, breeding status and management methods in Khmer for extension workers, related stakeholders and especially farmers to combat against GAS.

Title:
Techniques and Tools to Promote Investment in Agriculture
Description:
 Agricultural growth is at least twice as effective in lifting people out of poverty and hunger as growth from other sectors. In fact, many countries that have consistently invested in agriculture have made great strides in halving the proportion of hungry people, the target set by the first Millennium Development Goal.

INFLUENCE OF TEMPERATURE AND HUMIDITY REGIMES ON THE DEVELOPMENTAL STAGES OF GREEN VEGETABLE BUG, NEZARA VIRIDULA (L.) (HEMIPTERA: PENTATOMIDAE) FROM INLAND AND COASTAL POPULATIONS IN AUSTRALIA, by Pol Chanthy , Robert J. Martin , Robin V. Gunning and Nigel R. Andrew. GEN. APPL. ENT. VOL 43, 2015
Description:
Summary
Laboratory studies were conducted to assess impacts of temperature and humidity regimes on the development of Nezara​ viridula (L.) (Hemiptera: Pentatomidae) from inland and coastal populations in NSW, Australia. Four temperature regimes, 25±2ºC, 30±2ºC, 33±2ºC, and 36±2ºC and two humidity regimes, 40±10% and 80±10% RH were applied in the experiment with a constant photoperiod of 14:10 h (L:D). The developmental time of the nymphal stage of N. viridula significantly decreased with increasing temperature. Percentage nymphal survival significantly decreased with increasing temperature or high humidity (80% RH) regimes. Longevity of N. viridula adults declined with increasing temperature or high humidity regimes and femalelongevity was longer than males. High temperatures (30, 33 and 36ºC) or high humidity significantly reduced reproductive performance and capacity of N. viridula compared to low temperature (25ºC) or low humidity (40% RH). However, high humidity significantly increased egg hatchability of N. viridula compared with a low humidity regime. Interactions of temperature and humidity regimes significantly changed incubation period, adult longevity, mating frequency, pre-mating period, egg-mass size and egg hatchability of N. viridula. Interactions of population location (coastal or inland), temperature andhumidity regimes significantly changed incubation period and pre-oviposition period of N. viridula. Temperature and humidity are important environmental factors for the development and reproduction of N. viridula. Higher temperatures shorten the length of nymphal duration, but reduce nymphal survival. The optimum temperature for the development and reproduction of N.viridula was 25ºC with 40 ± 10% RH. No differences in nymphal duration, nymphal survival, adult longevity or reproduction performance between inland and coastal N. viridula populations were found under different climate conditions. We show the importance of assessing all life-stages in the response to varying temperature and humidity regimes, especially in terms of assessing responses to climate change.
