Management Options for Major Insect Pest associated with Queen Pineapple
Figure 1. H. pseudococcina parasitizing on adult PPMB
1. Parasitoids
Encyrtid Parasitoid, Hambletonia pseudococcina (Compere)
Order: Hymenoptera
Family: Encyrtidae
Description: A very small parasitoid with clubbed-like antennae that can be parasitized up to 8 adult PPMBs
Figure 2. A) Nymphal and (B) adult stages of predatory earwig
2. Predators
- Predatory black earwig, Chelisoches morio
Order: Dermaptera
Family: Chelisochidae
Description: Has four nymphal instars that can reach up to 120 days prior from hatching to mortality and can consume 1-2 adult PPMB and up to 100 individuals of PPMB crawlers per day
Figure 3. Cryptolaemus montrouzieri feeding on adult PPMB
- Predatory coccinellid beetle, Cryptolaemus montrouzieri
Order: Coleoptera
Family: Coccinellidae
Description: A voracious predator with a long history in biological control against mealybugs that could potentially consume up to 20 individuals of PPMB crawlers and 1 PPMB adult per day.
3. Entomopathogenic Fungi (EPF)
EPFs are microorganisms that specifically infect and often kills insects and other arthropods. EPFs are eco-friendly and good substitute for chemicals
Three (3) isolates of EPFs against PPMB:
• Metarrhizium anisopliae (fig.4)
• Lecanicillum lecanii (fig.5)
• Beauveria bassiana (fig.6)
4. Botanical Insecticides
Botanical insecticides are naturally occurring chemicals extracted from plants or minerals to control or minimize insect pest population.
Botanical insecticides against PPMB includes:
• Jatropa curcas (fig.13)
• Murraya koenigii (fig.14)
• Spagneticola trilobata (fig.15)
Plant Parasitic Nematodes Associated with Queen Pineapple
Plant-parasitic nematodes are pests of agricultural crops and cause crop yield reduce when the roots are damaged. Pineapple is extremely sensitive to root feeding nematodes. Four genera of plant parasitic nematodes were found to be associated with Queen pineapple such as Rotylenchulus reniformis, Pratylenchus brachyurus, Xiphinema sp. and Helicotylenchus sp. as soil samples were collected and isolated.

Baybay Delights Vacuum Fried Jackfruit
Why Baybay Delights?
Baybay Delights is the name given to vacuum-fried and dehydrated jackfruit snacks that retain the natural smell, color, and sweetness of a well-chosen jackfruit variety, the EVIARC Sweet of the Department of Agriculture in Eastern Visayas, Philippines.
The Baybay Delights is a dream-come-true for all Baybayanons to have a delicacy they can call their own.
Healthy Delight in Every Bite!
Jackfruit is rich in dietary fiber which makes it a good laxative. also rich in anti-oxidant and vitamin C., it is one of the best fruit for the body
Jackfruit: the Proud Crop of Region 8, Philippines
The Department of Agriculture Field Unit No. 8 (DA-RFU-8) chose jackfruit in 1996 as its banner crop under the High Value Commercial Crop (HVCC) program. Under the Jackfruit Research and Development Program, the varietal collection and selection started. This resulted to the establishment of the Jackfruit Germplasm Collection. Selected varieties were mass produced and introduced to interested farmers under the Plant Now Pay Later (PNPL) Program. Five to six years later, the jackfruit plants under the PNPL program have started fruiting.
