PCR-Technique Reveal the Potential of Cheiracanthium isiacum as a Phyllocnistis citrella Predator

Abstract

The experiment was conducted in a small greenhouse of citrus plants to know the population dynamic and the relationship between the Eutichurid spider Cheiracanthium isiacum and the occasional pest Phyllocnistis citrella. There was a statistically significant difference within three times in dominance of P. citrella. Results show that it is possible to detect P. citrella DNA in C. isiacum by using PCR technique and confirm the greenhouse experiment that there is a specific relationship between it. Cheiracanthium isiacum may be important in suppressing this pest population below economic threshold
