Abstract


Harlequin Cockroach (Neostylopyga rhombifolia) is one of the household pests which transmit diseases in the environment. The development of resistance due to resistance has encouraged efforts to seek alternative biological control methods. Community – based plant species, Hagonoy Plant (Chromolaena odorata) and Zz Plant  (Zamioculcas zamiifolia) was studied  for  its  insecticidal  activity in Harlequin Cockroach at room temperature.

The study used five treatments which includes T1 – leaf decoction from Hagonoy and Zz Plant; T2 – expressed leaf juice from Hagonoy and Zz Plant; T3 – 20% Hagonoy and 20% Zz Plant leaf extract solution; T4 – 40% Hagonoy and 40% Zz Plant leaf extract solution and T5 – positive control, commercial insecticide (Baygon®).

The  data  gathered  were  tabulated  and  computed  using  Analysis  of  Variance (ANOVA) to determine whether significant differences exist in the length of time the Harlequin cockroaches are killed among the five treatments; and Scheffé's Test to find out where the difference lies and determine which among the five treatments has the greatest insecticidal potential.

The positive control and the 40% Hagonoy and 40% Zz Plant leaf extract solution have comparable effect in terms of the length of time it takes for the sample Harlequin cockroaches to die.  Thus, the application of the positive control, Baygon® and the application of 40% Hagonoy and 40% Zz Plant leaf extract solution are equally efficient in killing Harlequin cockroaches.

Ultimately, a great insecticidal potential of Hagonoy and Zz Plant was found out. For this reason, the researcher recommends the patenting of insecticidal product out of Hagonoy and Zz Plant which is efficient, cheap, economical, organic, and environment and health friendly.
